DESCRIPTION
LF10 Air Pressure Switches (25-175 PSI)
The LF10 pressure switches are used to regulate the tank pressure between two preset values on small (up to 175psi) electrically driven air compressors.
They are available with an unloader valve, which prevents compressors from starting under load, and an auto-off disconnect lever for manual cut off the compressor.
A four port manifold style is available which provides a means for easy mounting of valves and gauges.
