What is Air Filter Regulator ?
A device that used primarily for regulate pressure and
filtering the air for stable source of air to process control
equipment such as current to pneumatic (I/P) transducers
and control valve positioners.

Why is it important to regulate Pressure?
• Pressure is one of the most important aspects of ANY piping system.
•If pressure is too low, the system is powerless.
•And if it is too high, overpressure affects filters, tools, sprayheads, instruments any vital tool in a liquid piping system.

Uses of a Pressure Regulator:
1. As a control element- to ensure that downstream pressure does not exceed a
set point.
2. As a safety device- to protect equipment from harmful overpressure.
3. Regulate to the correct pressure range - so that a flow system or piece of equipment can
operate safely and effectively.

Simple definition:
• A pressure regulator is a normally-open valve
that takes a high inlet pressure and converts it to a
lower, pre-set downstream pressure.

What a Pressure Regulator
WON’T Do:(common misconceptions)
1. It can’t convert a low inlet pressure to a
higher downstream pressure – it won’t
function like a pump.
2. It won’t control backpressure.

Rotation of the pressure
setting knob compresses
the range
spring against the
diaphragm plate, opening
the main supply
valve.

As the outlet pressure
increases, it flows through
the aspirator
and acts on the lower side
of the diaphragm causing
it to move upward until it
balances the force of the
range spring.
This
balanced condition
maintains constant output
pressure with
changes in supply pressure
and output load.

If the output pressure
rises above the set pressure, the
relief valve opens and
bleeds the excess pressure to
atmosphere.

Conclusion The air filter regulator is a very important device in
process system to regulate the pressure and to filter the air.
Without this device, the over-pressure can occur and causing a damage to other device.
The wet and dirty air can cause corrosion and clogingto other equipments.
