The VAC-U-MAX Model 860/02 industrial vacuum uses a VAC-U-MAX air-powered vacuum cover with manual pulse-jet filter cleaning and non-stick filtration to capture particles as small as 0.5 microns. The portable frame includes a collection hopper with an automatic discharge valve and polybag loading accessory. When the vacuum is turned off, the collected powder automatically discharges into an off-the-shelf static-conductive polybag.
