(03-051) WFD - Wall Flex Duo - Weld Fume, Dusts & Gases - Self Cleaning filters - 1000 to 2600 CFM - PES **
The Wall Flex Duo is an ideal solution for SINGLE or DUAL workstations that require “capture at source” and/or ambient collection as well as filtration of airborne contaminants such as welding fumes, grinding dust, etc. This solution comes pre-engineered and ready to use. The two (2) "self-supporting” extraction arms offer at source capture of contaminants. The adjustable inlets capture fugitive emissions in an ambient/general ventilation fashion. Exhaust air can be optionally distributed through “Push-Pull” high velocity jets that project the air over 50’ & de-stratify the air in the upper echelons of the facility. This allows for best dilution of fugitive emissions (fumes not captured at source). In all cases, the contaminated air is filtered and returned to the facility. The Wall Flex Duo comes typically equipped with the following components:
  • Direct mount fan (1.5 HP, 115/1/60) Optional: 3, 5, 7.5, & 10 HP
  • High efficiency “Nano-fiber” cartridge filter
  • Filter cleaning system
  • Cam-lock dust tray
  • Dual blowback dampers
  • Two (2) Extraction arms, up to 43’ in length
  • 1.1 KW (1.5 HP)/115V/1/60Hz fan
  • Pre-wired switch
  • Motor overload
  • Cord and plug

Construction:

The filter box is made of powder coated 12-14-16 gauge sheet steel sheet. It comes complete with integrated wall bracket, extraction arm brackets, and all necessary installation components. Please note: Ducted systems will require duct and sheet metal components to be supplied by others.
Please note: extraction arms longer than 11' are required to be mounted to a column or wall and not to the underside of the filter unit. Additional sheet metal fittings and/or hoses and/or hose clamps may be required.
