Dust extraction for spinning area and collection chamber

Exhaust air from the spinning area is fed into the filter plant of FAS via pipes. A so-called pre-separator for heavy particles is located before the entrance to the expansion chamber. Separated material is transported out of the filter through rotary valves and screw conveyors. Trapezoidal filter racks are installed above the expansion chamber to hold insulating wool mats. A suction flow is fed through these mats via a clean gas duct and a fan so that suspended particles are trapped in the insulating wool mats. The mats are replaced depending on their contamination level.
