HS-D central vacuum cleaner from Hellmich

With regard to design, the HS-D model is not comparable with portable industrial vacuum cleaners, as it is permanently installed at a central point and connected with a system of pipes. The pipes have a nominal diameter and can be routed within a radius of 250 m. Suction connections are installed wherever needed, although only two extraction points can be operated simultaneously. Depending on requirements, different nozzles can be connected to guarantee optimum cleaning.

The dust is collected centrally at the installation point of the cleaner. Two different systems are available. With the tipping bucket variation, the dust is collected in a bucket and taken by a forklift for disposal. In the version without a bucket, the dust is transported, for example, directly on a belt conveyor or with a pneumatic conveying system.

In a number of branches, the collected dust can be recycled back into the production process or material stream.
