The W1685 is a powerful, yet portable dust collector with large collection capacity for a 1-1/2 HP model. This dust collector has air suction capacity of 1280 CFM and has a max static pressure of 10.1 inches. Static pressure is produced by the 12" balanced steel, radial fin impeller to move the wood chips into the collector. It's perfect for collecting wood, dust, and chips from sanders, router tables, jobsite table saws, benchtop jointers and planers, and other woodworking machines. The upper 2.5-micron bag (D4572) and lower plastic bags (D4573-5pk) can be purchased separately for any collectors that do not include them. The complete and easy-to-read W1685 manual was written by our U.S.-based Technical Documentation Department and is packed with useful information.
