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