Benefits

High vacuum and high pumping speed

RB-AV blowers operate as vacuum boosters with a primary vacuum pump, reaching vacuum down to approximately 0.001 mbar(a) and pumping speeds from approximately 200 to 30,000 m³/h.

Reliable wear-free operation

Two synchronized rotors operate without contact and with very small clearances, so the compression chamber has no sliding parts. This reduces wear and provides stable, reliable operation.

High energy efficiency

The optimized rotor profile and precise synchronization through high-quality gears provide high efficiency and minimal energy losses during operation.

Robust construction and long service life

The cast-iron housing and ductile-iron rotors provide high mechanical strength. Robust shafts and bearings ensure long service life in demanding vacuum applications.

Simple maintenance

A design without internal wear parts and inspection windows for checking the oil enable quick diagnostics and simple servicing with minimal maintenance costs.

Advanced sealing and protection system

A dual sealing system with FKM rings, labyrinth seals and optional water cooling provides reliable protection, safe operation and suitability for gases and vapors.
