Vacuum pumps

They generate vacuum, suck off air from surfaces, and convey light bulk material. Rising demands for smart interaction with control systems, precise and service-friendly controllers, and system efficiency have all led to the increasing use of speed-controlled vacuum pumps.

Vacuum pumps are often only equipped with a frequency inverter during their final installation. In order to simplify matters and achieve better performance, more and more vacuum pump manufacturers are offering their own modules with integrated inverters.

Typical applications

Packaging industry
Food industry
Plastics industry
Electronics and semiconductor manufacturing

Powerful and compact

The i550 protec with 22 kW (30 hp) IP66/NEMA 4X drives this vacuum pump. Thanks to the compact size and light weight 10.1 kg (22.2 lbs), the protec can be easily installed on a mounting frame or decentralized on the wall. The i550 protec is a very attractive solution in this cost-sensitive market segment.
