Benefits
Oil-free operation without contamination
The blower operates without oil mist in the process air, making it suitable for applications where process cleanliness matters. The system requires no service liquid or water cooling.
High vacuum up to 93%
The RB-DV series reaches vacuum up to approximately 93% (28'' Hg) at closed suction. Its high compression ratio supports efficient vacuum conveying and other industrial processes.
Patented air-injection system
A patented atmospheric-air injection system reduces gas overheating and energy consumption, ensuring stable operation even at high vacuum levels.
Minimal maintenance
Because the blower has no sliding parts, wear is minimal. The simple construction enables reliable operation, fewer service interventions and lower operating costs.
Suitable for many industries
RB-DV is used for vacuum conveying, packaging, paper production, contaminant removal, industrial cleaning and many other industrial processes.
Bulk-material handling
IndustryVacuum conveying of powders, granules and other bulk materials in process industries, such as sugar, flour and plastic granules.
Paper and packaging industry
IndustryVacuum systems for paper conveying, pulp drying and stable paper-web guiding in production.
Food industry
IndustryVacuum for food packaging, PET-packaging production and product handling on automated production lines.
Industrial cleaning
IndustryPowerful vacuum systems for removing dust, waste and other contaminants in industrial processes.
Energy and environmental technology
IndustryGas extraction, such as methane extraction from mines or soil, and vacuum applications in energy and environmental processes.
