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

Wide range of pumps available

With more than 80 models in single-stage, double-stage, single and twin impellers to choose from, we have the suitable blower available for your application

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

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
