Amana-Goodman B1370133 SPST Pressure Switch -0.35" Water Column

The Amana-Goodman B1370133 Pressure Switch is an essential part of Heating, Ventilation, and Air Conditioning systems, and particularly for Goodman and Amana brands. It is a single pole single throw pressure switch, that controls the circuit by the change in air pressure. This particular part is designed to react to small changes in negative air pressure, namely at -0.35 inches of water column -0.35” WC. In HVAC systems, this negative pressure is normally applied to check proper air flow.
