Marvair 70050 Pressure Switch 320788-703 018 orifice for Natural GasThe Marvair 70050 Pressure Switch is a critical safety component designed for precise refrigerant monitoring in Marvair ComPac wall mount air conditioners and heat pumps. This low pressure switch (LPS) is engineered to prevent compressor damage by breaking the electrical circuit when system pressure falls below safe operating thresholds. With a factory set open pressure of 35 PSI and a close pressure of 60 PSI, it ensures the system does not operate
