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
- Gases and vapours can be handled
- No sliding parts, therefore no wear
- Safe operation and minimum maintenance
- No oil mist
RB-DV series blowers are selected by applications requiring vacuum levels greater than 50% or 15” Hg (for applications requiring vacuum 0-50% / 0-15’’Hg see ROBUSCHI RBS P.D. Blowers). RB-DV series blowers are used in the following applications:
- vacuum trucks handling wet and/or dry waste (Industry, Municipalities etc...)
- Pneumatic conveying (Ash transport, Chemicals, Pharmaceuticals industry etc...)
- Central vacuum systems (Packaging, Vacuum cleaning etc...)
- Deareation plants (Plastic extrusion, Brick production, etc...)
RB-DV in the ATEX version available on request.
