Description of Vacuum pump DSZH WK-115N (1 st., 42 l/min, 4.2 kg)

Vacuum pump DSZH WK-115N is designed for evacuation of the refrigeration system circuit in order to remove air and water vapor from it. The presence of water vapor in the refrigeration system adversely affects its operation, so the depth of technical vacuum is an important advantage of the DSZH WK-115N pump.

The best purchase in my life, I will definitely buy it again.

Bought to service 2 split systems. Vacuumed continuously for 30 minutes at an air temperature of 27-30 degrees - I thought that it would burn out from overheating (the hand does not tolerate such a temperature even for a second), but survived. After the "break-in" (the first evacuation), the sound of operation became quieter. The oil in the attached bottle is approximately 60% - filling up to the middle line of the viewing window and 40% for topping up, but when it will be necessary for my…

Pros
  • Quiet (purrs pleasantly), cools quickly, does not stink.
Cons
  • No delivery. The description of the characteristics regarding the presence of a check valve on different sites is conflicting.
