A.J. Antunes 8023202113 Air Switch Set W/90' Tube At 0.30" WC

The A.J. Antunes 8023202113 Air Switch Set is an essential part of HVAC systems, which is used for measuring and regulating air flow. It has a 90’ tube and works at a pressure setting of 0.30”WC. They function by sensing changes of pressure in the HVAC ductwork, then when pressure hits the particular level necessary, the switch controls other parts such as fans or dampers. This level of control guarantees proper flow management of the air and increases the efficiency of the systems used as well as energy use. Advantages include better response of the HVAC system, stability of temperature, and possibly, lower energy use.
