The new Atlas Copco DB series side channel blowers

Introducing the Atlas Copco DB series Side Channel Blowers - a tested and reliable technology for rough vacuum levels suitable for industrial applications. The DB series are available in single and double-stage variants. Clean and dry, the DB series do not require oil to operate. This ensures a clean operation, free of emissions and no contamination to the process. They are designed to be robust, clean, compact, and silent suited for rough industrial applications with high efficiency. The modular construction of DB side channel blowers ensures efficient performance with minimal energy consumption.

Available in multiple variants suitable for a wide range of industrial applications

DBS series - Single stage and single impeller

DBS series - Single stage and single impeller

Ideal for applications requiring flow rates up to 1000 m³/h, for low vacuum levels up to 750 mbar.

DBD series – Double stage and single impeller

DBD series – Double stage and single impeller

Ideal for applications that need limited flow demand with vacuum levels up to 550 mbar that requires limited flow demand.

DBSt - Twin impellers and single stage

DBSt - Twin impellers and single stage

The twin impellers working in parallel allows for large quantities of suction air up to 1980 m³/h with discrete vacuum levels up to 700 mbar.

DBDt - Twin impellers and double stage

DBDt - Twin impellers and double stage

Double stage and twin impellers allow to manage high flow rates and higher vacuum levels. They are the most complex models suitable for large air flows and high vacuum levels.

Dry Claw Vacuum Pumps

The simplicity, robustness, efficiency and contaminant handling capability of the DZS design pumps make them the smart choice for your application. Built to your exact standards and quality, the new dry claw pump provides you with a trouble-free and cost-effective solution.

Mechanical Booster Pumps

Based on the simple Roots principle, our mechanical booster pumps remain the favorite pumps for applications where high pumping speeds are required for pressures in the region of 0.01 to 50 mbar. This pump must always be backed by another pump, which can deliver against a high-pressure differential to atmospheric pressure.

Dry Scroll Vacuum Pumps

The DSS vacuum pump is ideal for vacuum generation across the rough vacuum pressure range. Moreover, it is a welcome fit to any production floor due to its simple and elegant design.

Dry Screw Vacuum Pumps

At Atlas Copco Vacuum, delivering value to our customers and clean technology for the planet drives our innovation. We invest in technology like our range of dry screw vacuum pumps that deliver benefits like higher productivity, minimized energy consumption, operator-friendly control, easy maintenance, and lower operation costs.
