Description
The Lochinvar & A.O. Smith 100233301 -1.25″ WC Normally Open Air Pressure Switch is an instrument used to regulate the flow of air relative to changes in air pressure. This is done through its ability to detect changes in pressure of the air around it and, in response, switching the circuit as required. This is normally an open switch that is made to close the circuit in response to changes in negative air pressure, and opens in response to a preset level of pressure. Advantages of this pressure switch include increased efficiency of the system, increased safety, and accurate control of airflow in different applications such as heating, ventilation, and air conditioning, ventilation systems.
