General: Flanders Precisionaire Heavy Duty Fiberglass Filters are designed for use in any application where disposable panel filters are recommended. They can be relied upon for superior performance since they are specifically designed for heavy workloads. A wide range of standard face sizes is available, plus nearly any “special” size.

 

Construction: Flanders Precisionaire Heavy Duty Fiberglass Filters are designed with a one-piece moisture-resistant chipboard frame enclosing media. Standard frames are nominal 1 inch thick (3/4 inch actual) and nominal 2 inches thick (1-5/8 inches actual). The fiberglass media filter consists of continuous filament fibers bonded together with thermo-setting resin. Support grilles of perforated corrosion resistant steel or expanded metal are provided on both sides of the filter. The media pads and support grilles are continuously glued to the inside perimeter of the frame, resulting in exceptional strength and rigidity. This design virtually eliminates the possibility of media sag within the frame.

 

Flanders Precisionaire Part Number is 10255D.
