The DusTek Spot Filter is specifically designed to be installed at a conveyor transfer point, with the option to link standardized extractor units together for maximum flexibility of both filtration surface and exhaust flow. If required, the extractor units can be supplied with or without a filter housing that is accessible for maintenance from the side of the transfer box. Extractor units which conform to ATEX 114 (Directive 2014/34EU) for use in zone 22 are also available.

Avoidance of dust

Transfer points in conveyor belt systems are often characterized by the formation of enormous dust clouds, exacerbated by the dust created in the transfer box. This happens because the bulk goods that flow through the transfer box push along the air in the transfer point, while the descending bulk goods simultaneously suck in more air through the available openings: these are significant cubic metres of air, which most transfer points are not designed to deal with.
Result? The air velocity at the transfer point increases enormously, collecting fine particles from the material flow and blowing them out in the form of dust through all available openings. If you want to avoid dust, then it’s important to reduce the velocity of the air to below the critical velocity level by extracting some of the air from the transfer box.
