Ensure your HVAC system operates safely with this high-quality low-pressure cutout switch. Designed specifically for air conditioning and heat pump units, this air pressure switch acts as a critical safety monitor for your refrigerant lines. It is engineered to open the electrical circuit when system pressure falls to 50 PSIG, protecting the compressor from potential damage caused by low refrigerant levels or cooling coil freeze-ups. This essential air-proving component helps extend the lifespan of your cooling system by preventing operation under hazardous low-pressure conditions. Whether you are performing routine maintenance or a critical repair, this durable pressure switch provides reliable performance and precise control for residential and light commercial HVAC applications.
