AIRFIX A

Tables with types and technical information: page 4.7.

Flamco offers you a wide choice in the field of expansion vessels for potable water installationsThe use of Airfix expansion vessels offers the user a number of important

advantages. Airfix A and Airfix D expansion vessels are ‘through-flow’ vessels,

meaning that they are specially constructed so that they regularly ‘rinse’ themselves

with fresh mains water. In this way, still, stagnant water, which is associated with

the formation of detrimental bacteria, is eliminated from the equation. As a result,

the quality of the potable water is preserved. As the interior of the vessel is

coated there is no chance of the water coming into contact with untreated steel

even in the event of damage to the internal diaphragm. Therefore, should the

diaphragm become damaged the water will remain uncontaminated. By using the

Airfix A and D expansion vessels, you can also limit water wastage.

The Airfix A expansion vessel is supplied with a synthetic flow divider, suitable for T-pieces for pipes of max. 3/4 (22 mm).

This flow divider is placed in the standard T-piece (which is not included in the tank supply).

The Airfix A expansion vessel and T-piece assembly must be fitted in the cold-water installation of the boiler and through-flow is established.

USER ADVANTAGES AIRFIX A AND AIRFIX Du Very easy to fit.

u Covered inside and out with an anti-corrosion coating, both in the water half and

the nitrogen half.

u Neither the diaphragm nor the coating give off any dye, smell or taste to the water;

both have been approved by CE and the DVGW (in Germany).

u Can be used with any storage water heater.

u Can also be used in pressure boosting systems.

u Fitted with a butyl rubber membrane.

Flamco offers you a wide choice in the field of expansion vessels for potable water installationsWithout an expansion vessel for sanitary appliances, the safety-valve (inlet combination)

will leak water every time water is heated causing water wastage on each occasion.

This significantly heightens the chance of lasting leakage as a result of pollution or

calcium deposits building up in the area of the valve seat. This kind of serious water

loss can now be stemmed by using an Airfix A or Airfix D expansion vessel.

AIRFIX D

All Airfix A and Airfix D vessels are white in colour.

Both butyl rubber diaphragm and vessel coating are internationally approved for use in combination with drinking water, meeting the CE standards (2002/16/EC).

Airfix D vessels use a special T-piece (supplied) which aids through-flow with its internal divider to ensure full through-flow in the vessel.

An AirfixControl is fitted between the vessel and T-piece, enabling the Airfix vessel to be de-pressurized for maintenance work without the need for the installation to be put out of commission.

The vessel pre-pressure must be 0.2 bar lower than the pressure behind the pressure-reducing valve in the cold water pipe in order to guarantee a proper flow.

Internal coating prevents corrosion, even in case of a faulty membrane.

A reliable clamp construction which damages neither the vessel nor the diaphragm while allowing conservation of the entire vessel surface, something which is unthinkable in welded vessels without flanges.

Airfix A or D with Prescor B boiler valve

Directions on how to fit the Airfix

pressure expansion vessel

Airfix A or Airfix D expansion vessels should always be

used with a Prescor B boiler valve. The vessel must be

mounted in the cold-water pipe, between the Prescor

valve and boiler.

Airfix D-E

Pressure expansion tanks with exchangeable diaphragms, suitable for

use in hot-water, pressure boosting and water-management systems.

The Airfix D-E is a solid, stable tank which is

easy to fit.

It is a ‘through-flow’ tank with two flange connections which has an

exchangeable butyl diaphragm. The high-quality material of which the

diaphragm is constructed is your guarantee of low permeability

(which means that your gas will not leak away) and if used correctly,

renders permeability negligible. Airfix D-E tanks are fitted standard with

an electronic diaphragm-rupture sensor and an internally-coated steel

through-flow flange.

USER ADVANTAGES AIRFIX D-Eu Very easy to fit.

u Covered inside and out with an anti-corrosion coating, both in the water

half and the nitrogen half.

u Neither the diaphragm nor the coating give off any dye, smell or taste to

the water; both have been approved by CE and the DVGW (in Germany).

u Can be used with any storage water heater.

u Can also be used in pressure boosting systems.

Ensure that the double system connection is directly connected with the

main flow in the potable water installation.

Logical Airfix technology offers the user significant advantages

The Airfix D-E expansion tank can be used in pressure boosting systems,

on either the intake or compression sides of the pumps. These installations

are intended to prevent excessively low feeding pressure and help prevent

excessive pressure changes at low flow speeds. At the same time, they

reduce the number of times the pressure-water assembly needs to be

switched. The Airfix D-E expansion tank offers the precise solution for this.

AIRFIX D-E AIRFIX D-E-B AIRFIX D-E-L

Inspection port (from 600 litres above and below).

Pressure gauge with self-sealing valve case and an Rp 3/8 DIN 2999-1 connection to the tank itself.

Diaphragm-rupture sensor, basic appliance, display with red LED indicating diaphragm rupture.

Maximum permissible gas prepressure on delivery: 6 bars.Maximum working pressures 10 and 16 bar.

Airfix D-E tanks are coated green.

u Diaphragm-rupture sensor including signal cable.

Airfix D-E-B

For pressure boosting, potable household,

processing or fire-extinguishing installations.

Single steel threaded connection (without

through-flow function) and without electronic

membrane-rupture sensor. All materials used

in this tank are potable water quality.

Airfix D-E-L

Double system connection with

through-flow function. For use in hot-

water, pressure boosting and water-

management systems.

Airfix D-E

Double system connection –

the link with the connection pipe.

The Airfix D-E diaphragm expansion

tank has a gas space between the

tank wall and the exterior of the

membrane, and a water space within

the diaphragm. The configuration of

the gas space depends on the opera-

ting characteristics and the required

pressure. A pressure boost in the

water space will compress the gas

volume and fill the diaphragm, while

a reduction in pressure will lead to

draining of water. Should the pressure

in the gas space reach the set water

pressure in the installation, water will

be drained from the connection pipe.

In all operating conditions, water flows

through the tank with a very low loss

of pressure.

See the pressure loss diagrams that

are available as PDF files on the CD.
