Dust extractor NQS500

NQS500 is attached to a sharpening machine while the wheel is running and takes away the grinding dust before it reaches the room. Its motor is quiet, which is the point in a sharpening room that is often next to a changing room or a rental counter and is manned for the whole session; suction is selectable at a high or a low level.

The intake works as a cyclone, so the dust is spread through the filter instead of loading one spot of it, and the motor sits behind two separate filters. AVK lists the unit for its skate sharpening machines generally, not for one model.
