Description
The A.J. Antunes 8221210041 Air Pressure Switch is an essential element of HVAC systems, which is intended for measuring air pressure, varying from 0.05 to 1” WC. It comes with a 1/4” barb fitting, and it can be easily connected to a number of HVAC equipment and accessories such as furnaces, air handlers and ventilation systems. This switch works based on change in pressure; if the pressure is not as set, then the switch turns on or off a circuit. This functionality also helps in maintaining the right pressure for proper air circulation and protects equipment from pressure changes and for maintaining the right HVAC.
