1/2HP 7CFM Refrigerant Vacuum Pump 1/4 Air inlet Refrigeration All Copper Motor

  

Oil mist trap: five layers of filtration, effectively preventing splashing of oil smoke and lower noise. All-copper motor: real material can be seen. Vacuum gauge: intuitive and convenient High-definition vacuum gauge, shockproof and durable.

Name:DC brushless lithium battery vacuum pump. When starting vacuuming, the pressure is relatively high, the air outlet is large.

The vacuum pump has a large exhaust volume. So there will be oil mist overflowing with gas. This is a common feature of rotary vane vacuum pumps. Oil mist appears at first which is a normal phenomenon.

When the vacuum drops to a very low value, the exhausting volume is small and there will be no oil mist. Therefore, the vacuum pump should regularly inspect the oil level to avoid running out of oil.
