Downflo Workstation Booth Packs
Sophisticated FLUENT®* airflow modeling software revealed that DWS booth packs are designed for adequate and consistent capture velocities at the booth opening and throughout the booth; a reflection of Donaldson Torit’s commitment to technical research and development.
  • No system imbalance
  • No air turbulence
  • No hot spots
  • No uncomfortable draft inside the booth that can upset working conditions


  • 8 standard model sizes
  • Customized sizes available
  • Many options and accesories
FIlter Media Pleats
The innovation of shorter and stiffer filter pleats helps minimize dust entrapment and simplify filter cleaning. By reducing the height of the filter pleats from the standard 2 inches to 1.5 inches, the pleat wall is less likely to collapse or bend, which can encapsulate dust and prevent its expulsion.

*The Minimum Efficiency Reporting Value (MERV) of this filter cartridge has been determined through independent laboratory testing using ASHRAE 52.2 (2007) test standards. The MERV rating was determined at a face velocity of 118 feet per minute and loading up to four inches water gauge. Actual efficiency of any filter cartridge will vary according to the specific application parameters. Dust concentration, airflow, particle characteristics, and pulse cleaning methods all affect filtration efficiency.

***Sound measurements were taken in a hemianachoic chamber and under free-field conditions and do not reflect the influences of actual operating environments. Standard sound pressure levels were taken at an operator position of 1.5m high and 1m from each of the four sides of the cabinet.​
