High efficiency

Highly efficient side channel blowers with low energy consumption across the range and IE3 motors as standard

Low noise levels

Effective blade design of the DB series leads to low noise levels and a safer, quieter working environment on the production floor

Clean and oil-free

Due to the non-contact and oil free working principle, the DB series side channel blowers have clean exhaust air without oil and dust contamination

Reliable and long-lasting

Housed in a fully enclosed aluminum unit with PTO thermal protection on the motor and long-life bearings

Minimal maintenance needed

Modular design, non-contacting parts, no oil and nearly maintenance free

Technical Specifications

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.

DBS series - Single stage and single impeller

Ideal for applications requiring flow rates up to 1000 m³/h, for low vacuum levels up to -350 mbar.

DBD series – Double stage and single impeller

Ideal for applications that need limited flow demand with vacuum levels up to -450 mbar that requires limited flow demand.

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 -300 mbar.

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.
