The Fairchild 3400 Pneumatic Lever Operated Regulator is the combination of a Fairchild 1000 High Flow Pressure Regulator and a hand held operated lever mechanism with 120 degree maximum travel.
The Fairchild 3400 Lever Operated Regulator is designed to allow rapid changes in pressure settings at control stations and test panels. This high quality unit, capable of handling high flows and exhausts combines positive control with good sensitivity.
The Fairchild 3400 is recommended for use in systems requiring the execution of linear pressure features such as the control of a throttle in an engine or engine room. The regulator is the logical choice for rapid, “hands on” control in a variety of applications, including construction machinery, industrial and oil rig equipment, and cylinder operation.
