Atlas Copco has introduced the DB series vacuum pumps with side channel blowers. Based on an efficient operating principle, the vacuum is created by the kinetic energy of the rotating impeller. The impellers are connected to the motor shaft and enable suction of the pumped medium, which is accelerated in the side channel. Suitable for rough processes, side channel blowers are designed for applications where high flow rates are required. The company says this makes the dry rough vacuum of the DB models suitable for rough industrial processes—such as drying, pneumatic conveying or suction processes. 

The vacuum pumps have a modular design for high efficiency, reliable performance and quiet operation, according to the company. Due to the dry, non-contact pumping principle, the exhaust air of the DB vacuum pumps cannot be contaminated; the vacuum is free of oil and dust, without any emissions or impurities.
