Pneumatic Pressure Regulators
A pressure regulator reduces an unregulated high input pressure to a regulated lower output pressure. Its primary function is to maintain the regulated output pressure under flowing and non-flowing conditions.
Fairchild manufactures a complete line of precision pneumatic regulators including positive pressure, back pressure and vacuum models. Quality engineering and manufacturing excellence assures that our pressure regulators meet all the requirements of a precision device.
Our large selection of pressure ranges and flow capacities lets you select the models that meet your needs for instrument or general industrial control applications.

Pneumatic Volume Boosters
A pneumatic air volume booster reproduce a low flow control signal with a higher regulated flow output pressure. It uses an unregulated input pressure to maintain a regulated output pressure under flowing and non-flowing conditions.
Fairchild volume boosters meet all the requirements of a precision device including:
- Accuracy
- Sensitivity
- Fast response
- Stability
- Drift-free settings
- Low output droop
- Supply pressure immunity
- High forward and exhaust flow capacity
The regulated output of a pneumatic air volume booster can be any of the following:
- A direct reproduction of the pneumatic control signal
- A multiple of the pneumatic control signal
- A fraction of the pneumatic control signal
Our large selection of pressure ranges and flow capacities let you select the models that meet your needs for instrument or general industrial control applications.
