The W1868 Cyclone Dust Collector provides the efficiency of a 2-stage cyclone system with the portability of a single-stage dust collector. Featuring an impressive 1023 CFM and up to 10.9" of static pressure, creating a vortex of incoming air that extracts heavy wood chips and large dust particles into a plastic-bag-lined 20-gallon steel drum. The remaining fine dust travels past the 13" aluminum impeller, is caught by a canister filter and then deposited in a separate plastic collection bag. The spun-bond polyester filter catches 99.9% of particles to 1 micron in size and is pleated to provide maximum surface area for efficient air flow. A turn of the filter cleaning handle rotates the paddle brushes, knocking caked-on dust off of the pleats to keep your CFM as high as possible. The collection drum features a quick-release handle that makes it easy to roll it out for sawdust disposal. Features include high surface area pleated filters with paddles to mechanically knock off dust cake, remotely controlled magnetic switches, easy lid lifting levers for emptying collection drums, and a compact design for moving around the shop.
