This 5HP Industrial Dust Collector with 12" balanced impelleris designedfor any dust collection task - day in and day out. The dust and shavings are sucked through the impeller fan blade and then the waste falls into the lower bag, the air being exhausted through the top filter bag, collecting some of the fine dust on the way. This type of extraction shifts huge volumes of air at low pressure and they are very efficient at removing bulk waste such from Planers, Thicknessers& Wood Lathes etc.It comes with two top filter canvas bags and two lower dust collection canvas bags. The built-in mobile base can move the machine anywhere in the workshop. This Industrial Dust Collector can easily handle three simultaneously running woodworking machines in a large-sized shop. The fine filtration efficiency can be improved somewhat by fitting a optional filter cartridge instead of the bag.
