The DHS 3000 VSD+ dry-screw vacuum pump was designed specifically for massive-flow industrial applications. A dry technology, it is well-suited for paper processing, conveying technologies and pick-and-place applications in the food industry, as well as a central vacuum system. Powered by a highly efficient IE4 motor with a patented asymmetrical rotor design, users benefit from energy savings of up to 50% compared to competitive products. The low-maintenance, compact vacuum pump has a low noise level and also runs vibration-free. An integrated intelligent control system with frequency converter automatically adjusts the speed of the DHS 3000 VSD+ to the requirements, ensuring that the exact vacuum level required is delivered in each process section. This results in significantly lower energy consumption and reduced wear on all moving components. Overall, this also extends the maintenance intervals and service life of the vacuum pump. A wear-free gearbox ensures optimum power transmission from the motor to the screw. The oil-free technology and simple, robust design also contribute to low maintenance costs. Other features of the pump include: paper filters that protect against dust and particles; a compact footprint; adaptation of flow to read demand; and a full-service preventative maintenance plan. — Atlas Copco, Stockholm, Sweden www.atlascopcogroup.com
