On-demand filter cleaning thanks to pressure differential measurement
Particularly efficient within 3.5 sec. per filter, with the force of 330g
Patented rotary valve for optimal use of PE bags AND fleece filter bags
Plastic accessories, floor nozzle 30 (BG Bau recommended)
with basic equipment for connection to the power tool. For the toughest continuous use, for direct extraction of hazardous fine dusts during drilling, milling, grinding and sawing work, concrete, plaster, stone, cement, wood, paints, varnishes (hazardous dusts, dust class "M"). A highly intelligent electronic system measures the negative pressure before and after the filter (pressure difference measurement "DDM").
As soon as the vacuum falls below the factory-set value, the impulse filter cleaning system switches on automatically and cleans both filters in succession within 3.5 seconds, without interrupting work. Even the most difficult fine and problematic dusts - such as gypsum - are easily removed from the filters. Advantage: cleaning as required with a constant high air flow, optimum force effect on the filter, significantly reduced system costs due to longer filter service life, saves time and costs.
