MicroGlass Air Cleaner

MicroGlass Air Cleaner

The new M72 from Air Quality Engineering Inc. is an in-duct media air cleaning system. It features the MicroGlass Extended Service Filters for long filter life and high efficiencies to effectively remove smoke, mist, dust and other  airborne contaminants at a rate of up to 6000 cubic feet of air per minute. Multiple units can be used for additional capacity.

  • Extended service life due to large filter media surface area of 400 sq. ft. total.
  • Low filter pressure drop for reduced energy consumption and cost.
  • Air flow capacity up to 6000 cubic feet per minute.
  • High contaminant-holding capacity that results in low maintenance (fewer change-outs) and disposal costs.
  • Increased efficiency during service life (no particle migration or fiber breakoff).
  • Higher recommended final pressure drop (longer filter life) than conventional bag filter systems.
  • Stacking capacity up to 36,000 CFM with optional hardware.
