Amplify the dust extraction capacity of your dust collector with the POWERTEC 75043 Fleece Bag for VacMaster VK811PH and VK1011SIWTH, 3 PK. These premium, high-efficiency bags have the unique capability to continuously self-clean, and thus ensure a nonstop peak performance that actually increases with use and lasts until the bag is virtually full. The micro fibers of the bag’s 5-ply fleece pick up a wide variety of particles that paper bags just don’t capture, from large-sized debris to fine particles; this insures that sawdust, other micro-dust, allergens, cement and drywall dust, small particulate matter and other unwanted pollutants get sucked out of your environment and into these rugged, secure bags. And because fleece acts as a potent filtering layer, there is less stress put on both the filter and the motor of your dust collector itself, thus preserving and protecting your whole dust collection system - and you won’t need to clean your filter nearly as often. These superior bags are both tear and clog resistant for maximum durability and utility. Lastly, a well-designed port-flap delivers a tight, secure closure that effectively prevents dust/debris from leaking into your shop environment during waste disposal. Cleaner, fresher air and tidier workroom surfaces are a cinch to achieve with these high-performing vacuum bags. This innovative accessory will be a strong link in your dust collection system. Available in a handy 3PK.
