It is suitable for commercial and residential applications, including refrigeration equipment maintenance, HVAC repair, resin degassing, and other vacuum applications. Equipped with a 1/4" SAE inlet fitting, it can meet your vacuuming needs in various scenarios—its versatility makes it ideal for industries such as HVAC, automotive, laboratory, and packaging
• SAFE OPERATION: The vacuum pump HVAC employs advanced noise reduction technology, minimizing operating noise to 65 dB or less, creating a comfortable working environment. The oil cap features a built-in cotton filter that separates oil mist from exhaust gas, reducing environmental pollution and eliminating the risk of oil splashing. Its excellent starting torque design ensures easy starting and high efficiency, allowing for perfect operation even at lower ambient temperatures and voltages
• LEAK CHECK METHODS: Methods for checking vacuum pump for ac system leaks: 1) Connect the air conditioning vacuum pumps inlet to a vacuum gauge. 2) Tighten all inlets, start the machine, and check for oil mist after a few minutes. If there is no oil mist, the air vacuum pump is in good condition. If smoke continues to come out, the A/C vacuum pump is leaking. Note: A refrigerant pressure gauge cannot detect vacuum levels. Please repeatedly check that the external connections are tightened
