Central dust disposal system reduces costs and risks

As soon as several filter plants and/or mobile vacuum cleaners are in use, the question arises as to whether a central dust extraction system makes sense?

Where several filter plants are used, instead of the dust collecting bin beneath the filter, a pneumatic conveyor is connected which conveys the dust to a central plant. This is certainly recommendable where toxic dust is involved, which has to be disposed of with minimum or no contamination. The enclosed system then runs into a contamination-free discharge system, which is housed in addition in a container under negative pressure (glovebox).

Instead of individual mobile vacuum cleaners, a network system with a central vacuum cleaning system is used. This can take the form of a branched system of vacuum cleaners over several levels, where air sockets can be fitted for the suction hoses wherever needed. Given the required negative pressure, which can often be 500 mbar, Herding often uses round filters with side channel compressors.

Herding also supplies systems where both filter plants and vacuum cleaners are connected to the central vacuum cleaner filter plant at the same time. In this case the plant was designed for an air rate of 2500 m³/h.
A central dust disposal system can also be installed retroactively as part of modernization work.
