The PM1900 Dust Collector features the exclusive TurboCone™ which improves chip separation to prevent clogging of the filter, and increases packing efficiency of the collector bag. The canister filter offers superior filtering surface area over standard bags, and captures 98% of 2-micron particles. A digital timer can be set for up to 99 minutes, and an infrared sensor allows remote control operation. The all-metal duct improves rigidity and air flow. The clear collector bags are large capacity, which means less down-time changing them. Four swivel casters and conveniently located handles allow for easy mobility.
