Automatic Power-off: The VEVOR refrigerant recovery tank is equipped with a floating switch. The initial setting is to automatically power off and suspend when 80% of the capacity in the tank is recovered. You can also set it by yourself to effectively control the recovery capacity. The entire recovery process does not need to be watched.

Strong Compatibility: The built-in 1/4" SAE interface valve can be adapted to fit most hose sizes, thanks to the inclusion of 2 1/4" SAE to 1/2" ACME brass adapters. Perfect for use with old household air conditioners, the tight connection at the interface minimizes the risk of leakage.

Explosion-proof & Non-leakage: Featuring an integral forming brass Y-valve with strong sealing capabilities, it can efficiently recover and discharge both liquid and steam. And, with the included pressure relief valve, you never have to worry about high pressure. If the tank's working pressure is exceeded, the valve will automatically relieve pressure for a safer user experience.

Cover Your Needs: With a 30 lb capacity, it's perfect for household vehicles. And, it's designed to handle a wide range of refrigerants including R134A, R-22, R-12, R410A, R404A, R502, R1234YF, and R32. Get the versatility you need.
