Daikin-Mcquay 71896001 Differential Pressure Switch 0-150 PSI

The  Differential Pressure Switch 0150, commonly known as Daikin-Mcquay component number 71896001, is an essential safety device for safeguarding HVAC equipment. In particular, it keeps track of the variations in air pressure between coils or air filters in Daikin-Mcquay HVAC systems. Significant airflow restriction from a clogged filter or filthy coil can lower efficiency and perhaps cause equipment damage. By automatically shutting off the system whenever the pressure differential rises over a safe threshold, this switch serves as a safety measure. This ensures peak performance and prolongs the life of your HVAC system by preventing equipment overheating, strain, and potential breakdowns. Additionally, by stopping unclean air from entering the system, it can aid in maintaining high indoor air quality.
