The Cantek UFO102B 3HP Dust Collector is ideal for the small shop looking to collect wood dust or for the larger shop to provide additional dust collection beyond the capacity of their central system.  The upper and lower bags are made of cotton and help filter the collected air before it is recycled into the shop and also collects the dust for disposal.  The base is mounted on casters so it can be taken to where it is needed in the shop.
