FOR CONVEYING AIR
Proven 2-lobe or 3-lobe blower technology for plant engineering for forced conveyance at extreme negative pressure up to 80% vacuum. Oil-free and extremely robust. Belt or direct drive version. For stationary and vehicle application.
DESIGN
● Housing with additional third socket on suction side for pre-inlet cooling
● series GM . . . Sm with lube oil supply by splash lubrication. 6 sizes, intake volume flow 60 up to 16.000 m³/h
● for an absolute pressure at inlet of approx. 200 mbar against atmosphere.
● series GM . . . Lm with central oil circulating lubrication. 3 sizes, intake volume flow 16.000 up to 50.000 m³/h for an absolute pressure at inlet of approx. 400 mbar against atmosphere
SHAFT SEALINGS
The conveying chamber is sealed by means of an oil slinger in combination with 4 piston ring labyrinth seals with a central vent chamber.
The drive shaft is sealed by double radial seal rings with grease barrier.
DIRECTION OF FLOW
Vertical, from top to bottom.
DRIVE
Direct coupling with motor or via spur gear resp. narrow v-belt drive up to size 19 for all loads.
