Furnas Brand Description

The 69M pressure switch is used to regulate tank pressure between two preset values on small (up to 175 psi) electrically driven air compressors.   Unloader valve to prevent compressors from starting under load and auto-off disconnect lever for manual cut off are optional.  A four port manifold which provides easy relief valve and gauge mounting is also available.

The rugged 69H pressure switch is designed for the demanding requirements of large, heavy duty commercial compressors (up to 250 psi).  Sturdy painted steel case and cover resists the harsh conditions encountered in industrial applications.  An unloader valve is also available on the 69H provided by Spec Tech.
