Prillwitz manufactures three kind of dust collectors: the HDFA Filter, that accurately separates grain from impurities - such as dust and glume - due to its cyclonical device; the HDFQ Filter, that economizes on space and reduces costs; and the small HDFT Filter, particularly suitable for pneumatic conveyors and silos because they are designed to handle reduced volumes of air.

The former filter is ideal anytime an accurate separation of dust needs to be performed.

The ¨auto-cleaning¨ system has enabled to notably reduce filters´ size, consequently improving its performance.

Dust control units are manufactured with either one or two air inlets. They can also have a cone unloader, a flat discharge bottom, and a bridle that allows the filter to be mounted on bins.

Vacuum system functions up to -0,3 bar, by overpressure up to +0.02 bar.
