The LF10 pressure switches are used to regulate the tank pressure between two preset values on 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.

The rugged LF17 pressure switch is designed for the demanding requirements of larger, heavy duty commercial air compressors (up to 250psi). The sturdy painted steel case and cover resist the harsh conditions encounted in industrial applications. This style is available with an unloader valve to prevent the compressor from starting under load.
