VOIGT - Canal Air Filters are used as suction filters for fans, compressors and vacuum pumps.

According to the operational area, the stream favourable designed canal air filter is available in three various designs. Should be sucked in external air the canal air filter is one-sided equipped with a weather protection made of lamellas and on the other side with an outlet flange. Should be sucked in circulating air, a simple screen grid, instead of the weather protection, is sufficient. By fitting into a canal, without straight air inlet, the canal air filter is double-sided equipped with a flange. For all flanged connections it can be chosen between weld-on flanges according to DIN 2576 or ANSI and flat flanges according to DIN 24154.

All metal parts of the filters are optionally made of stainless steel 304 resp. 316 or steel RSt 37-2.

According to the application, pocket filters, frame filters, compact filters or suspended matter filters are optionally set in into the integral taking up frames of the canal air filter.

The quantity and the design of the filter inserts are determined according to the technical data of the system.

In cases with extended air volumes it is from time to time necessary to use several filters, next to each other and on top of each other, as a filter bank.

By means of an appropriate revision opening the filters can be easily replaced by the maintenance staff.

A device, inter-balanced to the type of filters, guarantees for the absolute tightness of the system.

If required it is also possible to fit in filter inserts with different filter classes one behind the other to get a graduated coarse and fine filtration. Therefore, for each individual filtration stage, it is built-in an own revision opening into the canal air filter.
