Pneumatic 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
