Description
The Daikin-McQuay 071896001 Differential Pressure Switch is an essential part of HVAC systems that measures pressure differentials in the range of 0-150 PSI. This part works by measuring the pressure differential between two points in a system and it then can switch on/off other equipment for example fans, pumps, and ventilation systems depending on set points. Its main uses include the control of airflow in air handling units, checking on filter status, and protection from overheating in heating systems. The advantages of this differential pressure switch are numerous it improves energy efficiency because, through demand-controlled ventilation, it allows the fan to work with real-time air demand, and not at full capacity.
