Description
The Lochinvar & A.O. Smith 100208391 Air Pressure Switch is a crucial accessory for HVAC systems, especially boilers and furnaces. The presence of this plate ensures the safety of a unit, it prevents the unit from operating when the air pressure is either low or non-existent. The switch works based on pressure inside the combustion chamber of the engine in question. In the event of a pressure dropping below the established level the switch blocks the ignition circuit hence stopping the unit from starting. Using this switch can assist in ensuring that your HVAC system runs safely and efficiently hence fulfilling its purpose effectively.
