Oneida Dust Deputy DIY Deluxe Cyclone Separator is a universal attachment designed for wet/dry vacuums that uses centrifugal force to cyclonically separate and remove 99% of dust particulates before they reach the filter. This efficient method helps increase filter life and maintain suction capacity. The DIY version can be adapted for use with any make, size, or model of wet/dry vacuum. It is injection molded from a translucent anti-static resin and features tapered inlet and outlet ports for secure fittings with various hose sizes. The integral bottom flange bolts to the dust receptacle of your choice. It has a 2" inlet/outlet size. Please note that the vacuum, hoses, and dust buckets are sold separately. Model Number: AXD001004
