The LF10 pressure switch is used to regulate the tank pressure between two preset values on small (up to 175psi) electrically driven air compressors. It is 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. |
