This Lochinvar component is an Air Pressure Switch, a critical part of many HVAC systems. It functions by detecting changes in air pressure within a system and responding accordingly to maintain optimal operation. The switch operates within a specific pressure range, which is calibrated to the needs of the particular system it is installed in. When the air pressure falls below or rises above this set range, the switch activates to either turn off or turn on the system. This ensures that the system does not operate under potentially damaging conditions. The Lochinvar Air Pressure Switch is designed for durability and reliability, with a robust construction that can withstand the rigors of constant use.
