If you’re into 4WDing, the need to lower your tyre pressure to gain that extra bit of traction is a neces-sity, and the need to

reinflate them is just as important. If you’re without an air compressor, you’ll either be tempted to drive off-road with high pressures, spinning wheels and destroying tracks in the

process, or you’ll lower your tyres for the day’s 4WDing, then be tempted to drive home without reinflating them.

In years gone by, you had very few options when it came to buying an air compressor. These days, with free trade deals between other countries, we have seen the air compressor market grow to a point that it seems

every man and his dog has their own brand of compressor.

We came to the conclusion we needed to track down all the players in the market, and offer them the opportunity to put their products head to head in a battle to see which compressor would reign supreme. With 24 compres-sors sent in, it was always going to be a mammoth effort splitting

the field to show who has the best quality, reliability and value for money. It’s taken more than a month of organisation and rigorous testing, but here it is – our 100% no-bull, mega air compressor comparo!

The first test involved inflating a flat tyre from 0psi up to 40psi, just as if the tyre had gone down overnight at camp. This was done using a 285/75/16 Cooper STT tyre that we had mounted on a LandCruiser steel rim, which we modified with two values – one for inflating and one for the installation of a tyre pressure gauge. By installing a gauge to the opposite side of the rim, we were able to get accurate pressure readings on the fly, without having to stop the compressor and use a tyre gauge.

To ensure the tests are as close to a real-life scenario as we could get it, we mounted the wheel and tyre on the front of our 100 Series LandCruiser, which is kitted out with a steel bullbar, winch and side rails. Doing this ensured the full weight of the ’Cruiser was on the tyre during inflation, thus putting the compressor under the most strain that it would ever face in a real-world situation.

Before we inflated the tyres, we checked the starting temperature of each compres-sor’s cylinder head, then remeasured this temperature at the same position once it had finished inflating the tyre. Measuring the before-and-after temperatures proved to be a good indication of how the compressor handled the job. Many times during testing, we noted that a struggling compressor registered higher cylinder head temperature readings. The ambient tempera-ture was also monitored during testing, and ranged between 16°C and 18°C. Tests were conducted outdoors with a consistent breeze that meant all temperature variables were covered.

We’ve listed the results for this test below, and there’s a full rundown on each compressor’s performance on the product spotlight page later in the comparo. If a compressor did fail at any point of the tests, it wasn’t allowed to continue through to the next test.

TESTINGWhen it comes time to purchase a 12V portable air compressor, there are a few things that will help you make a decision. Things such as pricing come first and foremost, as there is little need to go out and spend $1000 or more if you’re only going to use the compressor a couple of times a year to inflate your tyres. Then you will need to consider if the compressor will inflate the tyres at a speed that you will be happy with. If it takes an hour or more every time you come off the beach, you’re more likely to drive home with tyres that are under-inflated.

Our first test involved inflating a completely flat tyre to find out which compressor will do the job quickly and efficiently. Then, we recorded the time taken to reinflate from sand pressures to road pressures to give you an idea of how long you will have to wait when coming off the beach. Finally, we carried out an endurance test to truly punish the compressors, and see if they will last pumping up yours and your mate’s tyres – be-cause we’ve all got a mate too cheap to go out and buy his own compressor! This test will give you a good idea of reliability and speed. But enough talking, let’s get stuck into it shall we?

SplITTING THE FIElD

Our compressors range greatly in price, so the only fair way to test

them is to break them into categories. The first is the sub-$250

range – a portion of the market that many new 4WDers find

themselves buying into, as well as those that venture off-road less

frequently. This is without a doubt the hardest segment of the

market to excel in, because a lower purchase price does not excuse

poor performance.The $251–$500 section of the compressors are well-represented,

with plenty of offerings for those happy to spend a little extra in

order to ensure their unit works whenever it’s needed. Here,

performance is crucial, because when you’re paying extra, you

expect results.If you rely on your air compressor regularly, then the $501–$1000

category is what will interest you. These compressors cost more

because they’re supposedly a cut above the rest, and able to inflate

tyres whenever and wherever they’re required. It’s not fair to

compare the cheaper compressors to these, because they’re

entirely different segments of the market.And then there’s the big-daddy category – the ‘I spent five times

this amount on my first 4WD but absolutely, positively must have a

compressor that could inflate the Hindenburg’ category. We’ve only

got one player in this section, and it’s a fire-breathing monster that

looks impressive even in the cardboard box. On price alone, this

category is a different playing field to the rest of the compressors,

but is the performance out of this world?

TEST 2 INFlATION FROM 16–40pSI

TEST 3 ENDURANCE

This test entails the most common use of compressors: the inflation of a tyre from 16 to 40psi, and how long you will have to wait for each tyre to inflate from sand pressures to road pressure. During the test, we recorded the speed and temperature fluctuation of each compressor.

DUTY CYClESYou may have come across the term ‘duty cycle’ when talking about air compressors. The duty cycle is how long the compressor can operate for without being damaged, or without tripping the thermal cut-out switch (if one is fitted).

Most manufacturers will state how long and at what pressure the compressors can operate comfortably. There are few compa-nies that will offer a 100% duty cycle, meaning their compressor is able to operate continually without stopping, and if you are able to find one, there’s a good chance that it will be at the top of the pricing category.

This test is a replication of inflating all four tyres on your 4WD, plus all four tyres on your mate’s vehicle. This test was done on the same 285/75R16 (33x11.5x16) Cooper STT tyres, the same 100 Series LandCruiser that was used in tests one and two.

To keep the power up to the compressors, the vehicle’s engine was kept running at all times. We didn’t test current draw because it’s common sense to have your engine idling while you air up, and even the biggest compressor won’t draw more than an alternator can put out.

All eight tyres were inflated without turning off the compres-sor between each one, as this is how the average 4WDer uses their compressor. While inflating

one tyre from 16 to 40psi, the opposite tyre was deflated back down to 16psi using a tyre deflator. The time taken to inflate the first four tyres was recorded, followed by each individual tyre from there on. This way we could monitor if any compressors slowed significantly as they warmed up. Any compressors that fell short of completing the task will be explained in the product spotlight pages.

The Bushranger Power Air is definitely not for those that intend to be deflating and inflating their tyres on a regular basis. Due to the plastic housing, this compressor was difficult to get an accurate temperature reading, so we tested right over the housing and recorded what we found.

Note that this temperature is naturally going to be different than the cylinder head temperature, so you can’t fairly compare operating temperatures to the other compressors. We found this compressor to be a little on the slow side; that said, it kept pumping for a solid 1.5 hours without stopping. It got the job done and never stopped, which is as much as you can hope for from a sub-$100 unit.

The Bushranger RV Air is a pre-production prototype we managed to get our hands on. The tidy unit is aimed at the 4WDer with limited room in the vehicle, so they have made it small and compact.

Bushranger has opted to supply this compressor without a bag to help keep the overall size down, and although it is physically small, it has outperformed its more expensive cousin the Pro Air compressor in every test. Being manufactured by ViAir and registering a cylinder head temperature of just 62°C, this compressor should stand the test of time.

Here’s another compressor aimed at those on a tight budget. Similar in speed to the Dr Air 75LPM, the KCI unit was able to inflate four tyres from 16–40psi in just over 18 minutes. This isn’t fast compared to some, but it’ll perform the job without an issue.

This unit is very close in looks to the Max Air compressor, but when it comes down to it, the speed just wasn’t there. With a temperature reading of 137°C at the head unit and 102°C at the hose connection, you will need to let this compressor cool right down before handling.

It was unfortunate that the MCC 90LPM failed to inflate all four tyres from 16–40psi; something that you’d expect from your compressor after a big day on the tracks. Although the compressor was still usable once it had cooled down, it couldn’t inflate four tyres without tripping the thermal cut-out. Due to the time taken for the thermal cut-out switch to reset during testing, we had no option but to stop the test there and then.

The Dr Air Pro Flow 75LPM is a compressor aimed at the budget end of the market. This means it’s not a speed machine, but still does a reasonable job of inflating tyres. While taking nearly 20 minutes to inflate all four tyres may be acceptable to most, it’ll make you think twice about having to inflate your mate’s tyres as well. With a reading of 111°C at the cylinder head, this compressor managed to keep the temperature of the airline down to a mere 23°C. Nevertheless, it’s good to see the rubber insulation over the hose to compressor connection reducing the heat when it was time to disconnect it.

The MCC 72LPM is a great choice if you intend to only inflate your own tyres, because it failed to complete the inflation of all eight tyres. The compressor hit the safety cut-off on the fifth and sixth tyre, resetting within 30 seconds each time. It tripped again on the seventh tyre and failed to reset after 10 minutes, so it was pulled from testing.

That said, after letting the compressor cool for an hour, it was able to be used again. This would easily be avoided by making your mate buy his own compressor!

The MCC 150LPM performed well in most tests, being right up there with much more expensive units. Its only issue was that it tripped the thermal cut-out when inflating the seventh tyre during the endurance test.

The thing to keep in mind is that tripping the thermal cut-out doesn’t mean that the compressor in no good, as this is a safety item that ensures that the compressor doesn’t self-destruct. Simply let the compressor cool down after four tyres and you’d side-step the issue.

The Piranha Max Volume is one of three compressors that looked almost identical to the TJM and Dr Air 75L compressors, with all three showing similar scores to each other. It performed well, taking out the third place in its category, right between its look-a-like brothers.

Once again we saw readings over 100°C at the head, with a maximum reading of 114°C. This compressor proves you don’t necessarily need to spend big dollars on a compressor to reliably inflate tyres on your 4WD.

The Tigerz 11 is another one of three compressors that share similar looks and performance with the Dr Air 150L and Terrain Tamer TTAC3. If nothing else, it proves that this design definitely works! This compressor managed to keep its cool, only reaching 75°C at the cylinder head and 44°C at the air line.

The bright-yellow casings on the TJM Portable helps this compressor visually stand out from the pack. Sharing the same basic design as the Max Volume and Dr Air75L, it has proven that in the lower pricing bracket, this configuration performs well.

The bag obviously isn’t made specifically for this compressor as you’re required to take off the air filter when storing the unit, which can be a little annoying. All in all, with a five-year warranty and impressive performance to boot, it deserves serious respect.

The Bushranger Auto Max has been around for a while now, and as with all the Bushranger compressors, the build quality is right up there. This unit has a built-in pressure switch that allows you to install it to a vehicle and join it to an air tank with ease.

One downside is that to inflate the tyres, you need to hold the inflation trigger. After a while, it gets tiring and it could do with a catch to hold the trigger. When it came to heat, this was in the higher end of the spectrum, reaching 106°C at the cylinder head.

The ARB CKMP12 is a well-presented compressor kit coming in a sturdy plastic carry box. The compressor itself is one of the smallest compressors supplied, but holds its own in the speed department. This compressor proved size can be deceiving!

The only issue was during the endurance test, with the compressor blowing a small hole in the hose right near the fitting on the eighth tyre. This was due to the high volume of air being pumped, causing the head to heat up to a staggering 177°C. This compressor recorded the highest temperature readings out of all of the compressors.

The Bushranger Black Max is a solid performer that proved it could hold its own with the bigger units. The thing that stands out with this Bushranger compressor is its excellent build quality, topped off with a good coiled hose and carry bag.

The hose comes with an inline pressure gauge that has a built-in deflator close to the valve chuck, perfect for dumping the air if you overinflate a tyre when talking to your mates. Although it was slightly slower than the Auto Max, this unit was able to keep the temperature down to 88°C.

The Bushranger Max Air II seems to have had its fair share of look-a-like compressors over the years, but don’t be fooled, they are quite different internally. This is basically the same compressor as its brother Auto Max, just without the pressure switch fitted.

This did mean that the compressor was a little slower, due to the pressure switch giving the Auto Max a small boost when first connecting to the valve. The build quality was right up there with the best that we tested.

The Bushranger Pro Air is a compact unit compared to the other compressors from Bushranger. Compared to other compressors from the same camp, it doesn’t scream the same quality when you touch and feel, but it isn’t a beauty contest and looks aren’t everything.

It’s worth noting that generally the slower the compressor pumped, the lower the temperature readings were. This compressor recorded a temperature reading of 62°C at the cylinder head.

The Super Max is the big brother to the Max Air compressor. This unit reached 122°C at the head, but with the aid of two cooling pipes running along the side of the compressor, it managed to keep the airline connection down to 55°C. compressor comes with a braided airline, which reduces the chance of kinking and provides extra strength.

We like the plastic insulation over the hose fitting to compressor connection seen on all the Bushranger compressors from the Black Max and up, this allows you to disconnect the hose without burning your hand on a hot connection.

The Volcano is a unit we haven’t had the chance to test before. Being one of Opposite Lock’s newest goodies in the line-up, it proved itself to perform extremely well. This compressor comes mounted in a sturdy plastic toolbox and supplied with a quality rubber hose.

The Volcano came in second place in its pricing bracket and fourth overall, meaning it’s a compressor that demands attention. It registered 102°C at the cylinder head.

Just like its little brother, the Dr Air Pro Flow 150LPM has a rubber coating over the hose connection that protects your hands from the heat of the compressor when disconnecting the hose. The speeds were just outstanding; it was first in most speed tests in its pricing category, only being beaten in the 0-40psi test. It proved to have an excellent pumping capacity at higher pressures where others started to drop off. It’s also surprising that although most of the faster compressors gave high temperature readings, this unit produced a reading of 54°C at the cylinder head.

The TTAC2 suffered a failure on the first test, blowing a hole in the hose near the compressor. We thought maybe we had a faulty unit and requested a second unit to retest, but the same issue arose! This was unfortunate, because the compressor has tested well in the past.

With a hole in the hose, however, we couldn’t continue with the testing. We contacted Terrain Tamer and explained the issue. Terrain Tamer was surprised and instantly decided to pull this compressor off the shelves and make some improvements, and told us it will not release the compressor back to the market until it passes Terrain Tamer’s own testing.

The Terrain Tamer TTAC3 is very similar in both looks and perfor-mance to the Dr Air compressor. It is supplied in a large bag that easily accommodates the compressor and hose. Even with a head temperature of 108°C, the airline connection was still cool enough to handle, only getting up to 50°C. Throughout the testing, it did well across the board and is definitely a strong performer.

What else can you say about the ARB Twin but ‘wow’? This kit is all assembled in a purpose-built case similar to the pelican cases used to transport expensive camera gear. Inside is the new twin-motor compres-sor with a cooling fan fitted. The addition of a remote-mounted air tank and cooling fan kept this compressor cooler than its smaller brother, but at 134°C it was still right up there in the temperature department.

This is one of the best built compressors we have seen in years, and the only thing that may stop people from buying it would be the price tag. All that said, if money weren’t an issue, this would be an outright contender!

The Opposite Lock Twin Tongue has been around for years and still performs well. Although a little expensive, the quality is right up there. The downside to this is there are a few compressors that pump as quickly, if not quicker, for less money.

This is where you need to look at your intended use. If you plan to use it regularly, it will be a compressor that will last for years. The Twin Tongue gave a temperature reading of 108°C at the head unit. Be aware that you don’t burn your hand, for the pipe between the heads may look like a handle, but it isn’t!

What a monster of a compressor! We asked all companies for portable units for this test, and Jedair sent us this beast of a compressor. The company stated that it is designed to be hard mounted, but can make a portable kit if required. This was borderline in the test due to its price and size, but we decided to give it a go, even though it weighs in at 33kg.

Smashing the speed barrier in tyre inflation, this compressor would give most workshop units a run for their money! This unit ran hot, producing 137°C at the head unit, meaning that it’s definitely worth keeping your hands clear and allowing a cooling period before handling. Being rather expensive, it isn’t a compressor for most, but if space and money don’t hold you back, this would be the one to look at.

The Piranha Red was formally known as the Big Red, but is now being distributed by Piranha and has had a name change to suit. It comes in a strong plastic toolbox that will put up with a lot of punishment, but proved a bit of a struggle when we tried to pack the hose away after use.

This is from the same manufacturer as the Twin Tongue compressor, and shares its same reliability. The downfall is its speed compared to price. While it wasn’t one of the hottest compressors we tested, it still gets warm enough to burn your hands on if you aren’t careful.

FINAL RESULTSNow the testing’s done, let’s sift through the data to come up with some hard facts and figures. In the course of preparing these results, we found that certain compressors didn’t just beat their rivals, some gave others an absolute hiding. For instance, there may have been 30 seconds difference between first and second place, but four minutes between second and third.

To simplify the scoring process and provide for the fairest scores possible, we adjusted the final placings depending on how quick each compressor finished the task, compared to how long the slowest compressor out of the entire 24 took. That gave us a percentage figure – the lower the percentage, the better the compressor. We then rounded those figures up or down to the nearest whole percentage, and gave each compressor both a category placing and an overall placing depending on that figure.

Simple, eh? Trust us, the numbers have been well and truly crunched...

This month’s major feature put 24 compressors head-to-head in a range of torture tests, conducted over five weeks and countless man-hours. Unfortunately an error in the design of the article meant that final results tables were printed incorrectly. This doesn’t in any way effect the overall scoring or final placing of any compressor; each unit was assigned the correct amount of points in the final tally, and the correct prices are displayed against each compressor’s individual specifications. Below is the correct table of results for all compressors. We’re sorry for any confusion that this has caused.

Before the final figures were tallied, we added in a final column – warranty. These ranged from one to five years: those offering a one-year warranty were awarded 50 points, two-year warranty 40 points, three-year warranty 30 points, four-year warranty 20 points, and

five-year warranty 10 points. Any compressor that failed to

inflate four tyres was given a DNF and not allowed to proceed with testing. However, those compres-sors that couldn’t make it through inflating the full eight tyres weren’t punished as harshly. The fact is

that should someone want to use your compressor to inflate their tyres after you’re done, all these compressors would need is a 15-minute cool-down and they’d be fine. In this case, any DNF on the eight-tyre test simply scored them 150 points.

COMMON AIR COMpRESSOR FAIlURES

MOTOR BRUSHES: These are a part that simply by design will wear out with excessive use.REED vALvES: These are designed to flex and with a lot of use can break at the flex point.AIRLINES: Some compressors came with hoses made of a poor-quality airline material. Once the heat from the compressor filters through to the hose, it can cause it to melt and fail. The quality of the hose clamps can also be a fail point, and if crimped clamps are used, they are difficult to repair in the bush.ELECTRIC MOTORS: The motors can suffer from dirt and water ingress. If either of these get into the workings of the unit, they can cause the motor to burn out, rendering the compressor useless.PISTON SEALS: The seals are often a form of nylon or Teflon. Neither of these are normally lubricated, and if contami-nates get past the air filter. they will cause premature wear. This will result in the compressor slowing in its inflation rate, and ultimately failing altogether.

COMPRESSOR BREAKDOWN

REED vAlvESThe reed valve is a one-way valve resembling a small metal tag. It acts to allow air to travel only in one direction into the cylinder, then once compressed, into the hose. Normally made from a thin piece of spring steel, these can fatigue over time and break. Depending on the manufacturer, these can be sold as a spare part.

CYlINDER HEADWhile some compressors look the same, the internals are often manufactured from varying quality materials. These two cylinder heads show the difference in wear after the endurance test.

MOTORThe motors on all compressors tested are series-wound 12V electric units. These are made up of a set of brushes that are seated on the armature. The armature spins when power is applied through the brushes, which creates an electromagnetic force that turns the crank.

Some of these motors have built-in thermal cut-outs near the brushes that cut power when the temperature rises to a pre-set level. The most common point of failure on this style of motor is the brushes. They wear in a similar manner to your brake pads, with some manufacturers offering these as a replacement part.

pISTONThe piston’s job is to seal the cylinder and compress the air charge with each upward stroke of the crankshaft. However, not all pistons are the same; these two pistons have been through the

same test and one is definitely showing signs of distress. Taking a close look at the cylinder walls, you can see that there is a lot of scoring, and this was proven to be a failure point of some compressors.

COOlINGExcess heat will destroy an air compressor in seconds. The cooler a compressor stays, the longer it will last. All the compressors tested rely on air to cool them, but this is achieved in different ways. Some just rely on the ambient air to flow over the motor and cylinder head, while others have cooling fins giving them a larger surface area to help disperse the heat and keep the head cool. Some bigger units have built-in cooling fans fitted.

AIR FIlTERSA poor-quality air filter could allow dirt and contaminants to penetrate into the seals of the piston, causing excessive scoring on the bore, or hold the reed valves open causing the compressor to lose efficiency.

HOSE CONNECTIONSIf there is one thing to take away from this testing, it’s the safety issue regarding the heat output of compressors. These hose connection points are often

quick-fit couplings made out of steel that can reach over 100°C, and easily hot enough to inflict a third-degree burn. This is most dangerous when you go to disconnect the hose from the air compressor after use.

Some compressors are great at cooling the air before it gets to this point, and others have insulated connectors. On the other hand, we saw plenty of unpro-tected connections that will require you to wear a pair of rigger’s gloves or allow a cooling period before handling.

HEATThe heat in an air compressor actually comes from the air itself being compressed. By compressing the air, friction heat is generated; the higher the pressure, the higher the heat will be.

We’ve proved that without good-quality cooling capabilities, these compressors can get to staggering temperatures. You should always take care when handling any compressor during and after use, and be sure to always supervise children whenever they are near the compressor. We all know little fingers like to touch the exact things they’re told not to!

THE WINNERS!

So what do all the figures boil down to? As we mentioned at the beginning of this article, the sub-$250 category is without a doubt the hardest to win. Just because a compressor is cheap, this doesn’t give it an excuse to perform poorly – it still has a job to do.

The MCC90LPM unfortunately failed to finish the four-tyre inflation test, so it was excluded from a final placing. The 70LPM and 150LPM units worked satisfactorily, however.

As always, Bushranger put on a strong performance. Its Power Air compressor has been around for years, and may be slow but proved once again it will pump all day long – fantastic considering the sub-$100 price tag. The TigerzII was the real surprise of this category. For a relatively new compressor, it matched performance with units well into the next price bracket.

But the quiet achiever of the class was the TJM Portable compres-sor. It never took first place in any of the tests, but consistently strong performances tipped it over the line. Congratulations to TJM for taking first place in this class!

If the lower price bracket was a hard battle, then the $251–$500 class was a full-blown war. A leaking air hose hurt ARB’s chances, especially frustrating because it performed so well up until that point. Bushranger had five entries into this class, with the Auto Max and Super Max scoring consistently well to take out equal third. Terrain Tamer’s TTAC2 suffered from a poor-quality airline, but we’re glad to hear that Terrain Tamer has pulled the model from sale as a result of this test and is in the process of upgrading it, and should be applauded for standing by the quality of its products enough to do so.

Opposite Lock’s 1Air turned out to be a strong performer, nearly taking out both class and overall bragging rights, but was just pipped at the post.

The three compressors in the $501–$1000 category were neck-and-neck throughout the testing. Piranha’s only entry into this price bracket – the Red – didn’t set the world on fire, but did chug away like a trooper.

It’s worth keeping in mind, however, that it is considerably cheaper than the other two in this category. The Opposite Lock Twin Tongue has always been a solid performer, and it didn’t disappoint this time, but it was beaten in the end by ARB’s new twin compressor. It hammered its way through every test, only really incurring points on cost and a shorter warranty than others.

Of course, the Oasis scorched through every single test, and if we hadn’t taken purchase price into account, then it would have walked away with the overall gong, but you didn’t need to read this test to know that!

And then we come to our champ – both of the $251-$500 category, and first place overall. The Dr Air Pro Flow 150LPM is a sensational piece of equipment that consistently placed at the top of its field in all disciplines, only being bettered in the initial 0–40psi test. A five-year warranty and sub-$300 purchase price mean that when the dust settled and we tallied the figures, it was the clear winner. Congratulations to Haigh Australia and to the Dr Air Pro Flow 150LPM for taking overall honours!

One thing’s clear after looking at all these compressors: as 4WDers, we’re spoiled for choice. The trick is to buy the best compressor you can afford, and then to allow sufficient cooling time to prolong its service life. Follow those two tips and just about any compressor you buy will give you years of faithful service!
