Continuous Duty Industrial Vacuum Cleaner for Fine Combustible Dusts

Item #: MDL850

The VAC-U-MAX MDL850 is designed to reduce operator exposure to fine powders and to improve material handling of dusty debris. The new continuous-duty industrial vacuums are equipped with a continuous bagging system that eliminates dumping of a drum or rigid collection container. The closed bags prevent fugitive dust clouds and avoid a potential cause of back injuries. The unique filter cleaning system eliminates the need for compressed air and solenoid controls, allowing the filters to collect the finest powders anywhere in the plant. The vacuums are also equipped with a 50 sq. ft. PTFE-coated primary filter, a standard HEPA secondary filter and easy-rolling 6”-diameter wheels. The new family of VAC-U-MAX vacuums is available in 2.5HP, 5HP and 8.5HP models. The vacuums are suitable for unclassified and Class II, Div 2 rated environments.

Standard Equipment


  • Power requirements: 480V/3-ph/60Hz, 30Amp service
  • Direct-drive vacuum producer with 8.5HP (6.4 kw) continuous-duty motor with nation-wide warranty service at over 5,000 locations.
