Technical Specs


WAMAIR Vacuum is a polygonal Dust Collector range which comes in mild steel, or 304 / 316 stainless steel. Filter elements are inserted horizontally or vertically. A compressed air pulse-jet cleaning system is integrated into the access door.
The WAMAIR Vacuum dust collector range includes a food-grade version whose parts in contact with the dust are certified ac­cording to the European regulation. Its design prevents accumulation of residue and makes it easy to clean. In this case, the dust collector is provided with a compliance certificate to the Food Contact Materials Regulation EC 1935/2004.
In case of potentially flammable or explosive materials, a version suitable for use in potentially explosive atmospheres certified according to the ATEX directive can be provided.
Its compact design makes this type of dust collector suitable for applications where limited space is an issue, maintaining efficiency in continuous operation.
Insertable Polygonal Dust Collectors for Negative Pressure Applications


WAMAIR Vacuum separates dust particles carried in suspension by an air current using pocket-type filter elements. The dusty air current passes through the filter media, which holds back the dust particles, allowing the clean air to flow through.
WAMAIR Vacuum is designed for pneumatic conveying systems in negative pressure conditions (up to -0.6 bar) meant to safeguard the vacuum pump. However, it can also be used for silo venting.
