High Vacuum Rotary Lobe Blowers RB-AV

A new range of high vacuum rotary lobe blowers, RB-AV series, are two-lobed vacuum blowers used to increase the capacity of primary vacuum pumps, operating at their minimum suction pressure (as a booster), along with a primary vacuum system (VP). It fits pressure levels lower than 33 mbar(a). These boosters are a type of positive displacement blower widely recognized for their efficiency in vacuum pump applications.

  • Vacuum up to 0.001 mbar(a)
  • Capacity from 200 to 30,000 m³/h

These boosters are usually used alongside primary vacuum systems like liquid ring, screw, vane, piston, or claw vacuum pumps. Most often, they are installed vertically above the primary pump, ensuring a space-efficient installation. As a trusted root blower manufacturer, we ensure precision and reliability in every RB-AV unit.

Ultra-Precise Rotors

Dual rotors with micron-level clearances ensure efficient gas sealing without contact, reducing wear and boosting reliability. This advanced rotary lobe blower design guarantees superior performance.

Robust Construction

Labyrinth seals and FKM O-rings keep the chamber clean and oil-free. Advanced rotor grinding guarantees dimensional accuracy and long-lasting performance, making it a preferred choice for positive displacement pump systems.

Enhanced Safety

Dual FKM shaft seals with integrated lubrication, optional water cooling, and a hardened sleeve provide maximum protection during operation.

Material Excellence

Cast iron casing and nodular iron rotors deliver strength and durability. Optional nickel alloy coatings and multiple sealing systems ensure corrosion resistance and adaptability for aggressive environments.
