Pulse-Bac model 550 is a HEPA vacuum with a filter fractional efficiency rating of 99.97% @ .3 micron at a CFM flow rate up to 140 (CFM revision June 2016) . The 550 model comes standard with Pulse-Bac® Automatic Pulse-Clean Technology, complying with the 2017 OSHA regulations that require a “back flush filter cleaning cycle” when using vacuums with materials that contain Silica, our Cyclonic Debris Management System, tank inspection windows, HEPA filters and a 15’ x 1 ½” crush proof self locking vacuum hose. An optional automatic tool start and three caster dolly is also available.
The 550 can be used for general cleanup, vacuuming carpets and hard surfaces or capturing dust and debris generated by hand held power tools and surface preparation equipment. Our revolutionary design in vacuum filtration automatically flushes the filters clear while you work, using only ambient air and vacuum. This patented technology stops the filters from facing with dust or debris and clogging during operation. Maintain peak performance with NO BLOWERS, SHAKERS, COMPRESSORS or BUTTONS to push. Just turn it on and go to work, Pulse-Bac® technology does the rest.
