Lochinvar & A.O. Smith 100111630 1.00" Air Pressure Switch

The Lochinvar & A.O. Smith 100111630 1.00" Air Pressure Switch is a necessary component of HVAC systems. It adjusts pressure within the combustion chamber to achieve the requirements of its safety and effectiveness during combustion. The diaphragm of this pressure switch changes according to the pressure of the air. The safety circuit stops the system's operation when the pressure goes below the given level to prevent conditions such as incomplete combustion or formation of carbon monoxide. The diaphragm of this air pressure switch changes with variations in air pressure.
