Lennox 34M76 SPST Pressure Switch 0.86" WC

The Lennox 34M76 Pressure Switch is an essential part of HVAC systems. This SPST switch works with a pressure setting of 0.86 inches WC to turn on/off electrical circuits depending on the pressure readings. It also makes it possible for applications involving HVAC systems, for instance, gas furnaces and air handlers not to have hazardous situations since gas flow is regulated to cease whenever pressures are below set values. The advantages of using the include increased safety due to accurate pressure monitoring, increased system efficiency due to proper airflow regulation, and decreased equipment damage due to pressure changes.
