Vaccum Pumps

One would need the vacuum pump to remove the air as well as water vapour trapped in the air-conditioning system after every repair job. Air and water vapour not only taking up unnecessary space, they are harmful also to the compressor. Normally, water will boil at room temperature of 25 degreeC when the vacuum pump reduces the system pressure to 25 mm of Hg. The vacuum pump should be left long enough (15 to 30 minutes) to remove all possible traces of moisture.

Vacuum pump should be capable of pulling at pressures twice the boiling point of the water or around 1 atmospheric or 760 mm or 29” Hg pressure.
