Vacuum pump range expanded

Side channel blowers are used in applications where high air flow rates are required. Cologne-based company Atlas Copco Vacuum Technique has now expanded its vacuum pump portfolio to include DB series side channel blowers.

This solution makes the DB models’ dry rough vacuum suitable for tough industrial processes – for example in drying, pneumatic conveying, suction processes or waste water treatment. According to Atlas Copco, the modular design ensures high efficiency, reliable performance and quiet operation.

The vacuum is created by the kinetic energy of the rotating impeller. These are attached to the motor shaft and facilitate suction of the medium being pumped, which is compressed in the side channel. The dry, non-contact pumping principle prevents the DB vacuum pumps’ exhaust air from becoming contaminated. Atlas Copco states that the vacuum is completely free of oil and dust, without any emissions or impurities. The models meet the cURus standards and are equipped with eco-design IE3 motors as standard.

Depending on the performance requirements at hand, the company offers the DB series in single-stage and two-stage versions, with customers able to choose between one impeller or double impellers. The variant with one impeller releases the pumped medium after one rotation, whereas it enters a second stage after one rotation in the two-stage design. The double impellers also increase the blower’s output. The two-stage design with double impellers can handle large air flows and achieves a higher vacuum level.

Atlas Copco can take care of maintenance planning and regular upkeep if needed as part of its Preventive Care Plan, which is tailored to the exact requirements of each pump. Regular maintenance is designed to help reduce operating costs, improve productivity and minimise downtime.
