Air injection vacuum blowers

The RB-DV series consists of 3 lobe rotary blowers used as exhausters which makes it possible to reach a high compression ratio by means of a patented atmospheric air injection device ROBUSCHI that reduces overheating of the gas and the power absorbed by the blower. The main characteristics of these blowers are as follows:
- Maximum vacuum 93% – 28’’Hg on a dead head;
- Nominal capacity from 840 to 10,500 m3/h – from 494 CFM to 6200 CFM;
- Suction pressure up to 100 mbar absolute / -900 mbar;
- Gases and vapours can be handled;
- No sliding parts, therefore no wear;
- Safe operation and minimum maintenance;
