A new range of high vacuum rotary lobe blowers, RB-AV series, are a 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 level lower than 33 mbar(a).
- 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.
