Bad Dust Bag Makes Sandblasting “Mess-Free”
You can sandblast an old tractor, pickup or car without making a mess using a “Bad Dust®” containment bag that completely encloses the workspace inside a bag.
  “It’s a very mobile unit can be set up outdoors or inside buildings,” says Roxanne Winslow, owner of the company.
  Instead of framework, the bags hold their shape with a low-pressure positive airflow - just a 1/3 hp blower is enough to maintain a 10 by 25-ft. automotive bag, for example. Exterior loops accommodate ground anchors or ceiling suspension to keep bags securely in place.
  “The product has been in use and gone through research and development for over 15 years. It’s very professionally made in the U.S. by a company that manufactures for the military,” Winslow says.
  Made of durable ballistic nylon fabric, Positive Containment Systems, LLC, can customize the bags to whatever dimensions are needed to fit a job, and zippers make the units modular to add on sections if more work space is needed at a later date.
  “For one customer in the marine industry, we made two separate 65-ft. long bags that were able to zip together to make a 130-ft. long bag for a much larger project,” Winslow says.
  Bags are easy to store in a stuff sack to be reused over and over. Clients appreciate that they can order a bag customized for their project and that zippers and buckles are interchangeable for future expansion, Winslow notes.
  Prices vary according to size. For example, a 10 by 10 by 25-ft. automotive bag sells for $3,500.
  Winslow points out that in addition to being convenient, the bags help customers meet regulations for controlling air-borne pollutants from various media blasting and other restoration activities. She adds that while painting can be done in them, they are not designed to be spray paint booths and the fabric shouldn’t be coated with paint.
  Bags and curtains of all sizes can be purchased through the Positive Containment System website.
