This high-quality low pressure switch is a critical safety component designed for HVAC and refrigeration systems. Functioning as an air proving and pressure monitoring device, it is engineered to protect the compressor by cutting out when refrigerant pressure drops to 25 PSI, preventing damage caused by leaks, restricted flow, or coil freeze-ups. The auto-reset feature ensures the system resumes operation automatically once safe pressure levels are restored, minimizing downtime and the need for manual intervention. Ideal for maintaining the efficiency and longevity of central air conditioning units and heat pumps, this durable pressure sensor is a reliable choice for professional HVAC repairs and routine maintenance.
Type: Air Pressure Switch
Size: Small
Application: Used in residential and commercial central air conditioning systems, heat pumps, and refrigeration equipment to monitor low-side refrigerant pressure and provide automated compressor protection.
