Rotary Lobe Blowers

From vacuum to pressure-vacuum operation, from stationary to mobile units, and for handling gases and vapours – Robuschi manufactures a comprehensive range of rotary lobe blowers.
Over 70 years of experience and know-how combined with the most advanced technological innovations goes into the development of every product.

Robuschi offers a number of pressure-vacuum operation rotary lobe blowers with capacities up to 25,000 m3/h. This range includes the innovative RBS series. These positive displacement low pressure 3 lobe rotary blowers feature 3 special profile lobes. Combined with the patented LOW PULSE system they reduce the residual pressure pulsation of the conveyed gas below 2% of the operating pressure.

The vacuum operation range of rotary lobe blowers from Robuschi have capacities up to 10,500 m3/h and includes stationary and mobile units. For mobile applications Robuschi presents the TRB-DV series rotary lobe vacuum blowers. These compact units have been developed for vacuum truck handling wet and/or dry waste and are equipped with a noise enclosure.

For high vacuum blower requirements the RBS-AV series from Robuschi provide the solution. These high vacuum rotary lobe blowers have suction capacities from 300 to 9,400 m3/h and suction pressure from 0.001 to 20 mbar (abs.). They are used as a booster to increase the capacity of a primary vacuum pump when operating at their minimum suction pressure.

From lifting, transportation, fixing, packing, melting, degasing, welding, extraction, vacuum-filtration, distillation and drying – the applications and industries where the Robuschi range of rotary lobe blowers can be found is extensive.
