Vacuum Blowers with pre-inlet cooling
Aerzen Positive Displacement Blowers

For pre-inlet cooling, the housing is equipped with an additional third socket on the suction side. The lube oil supply is effected by splash oil lubrication. The conveying chamber is vacuum-sealed tightly by a sealing system. The driving shaft is sealed with double radial seal rings with grease barrier. Direction of the flow is vertical from top to bottom. Drive can be effected via a direct coupling or via a narrow V-belt (at limited differential pressure).

Design with special materials (GGG 40 / GGG 40.3) is possible.
