Vacuum Blowers
Aerzen Positive Displacement Blowers

Housing flanges with O-ring-seals, vacuum-tight. Lube oil supply is effected by splash lubrication. Shaft seals by combined oil slinger-piston ring labyrinth seals. The driving shaft is sealed by double radial seal rings with grease barrier. Direction of flow vertical from top to bottom or horizontal clockwise (when looking on the driving shaft.) The direction of flow depends on the size.

Designed with special materials (GGG 40 / GGG 40.3), Rotary pistons/housing parts (GS-C25, CrNi-cast steel 1.4313/1.4407) is possible.
