The filter media consists of 100% high bulk poly- ester fibers that are thermo-bonded with a fire retar- dant res” Support grilles of 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 excep- tional strength and rigidity. This design virtually eliminates the possibility of media sag within the frame.

Precision Pak

Models PAPxxxSxxxx

High efficiency bag filter for use as a prefilter in downdraft booths and prep stations.

The Precision Pak ASHRAE bag use a fully syn- thetic media that provides an efficiency rating of 45- 55%. The pockets are hand sewn or ultrasonically sealed and fastened to an all aluminum frame. They are designed for specific booths and prep sta- tions that can accommodate their special size and performance properties. UL 900 Class 2 Listed.

Precision Pak bags have a large amount of media surface area. This decreases the pressure drop and increases the capacity. These bags hold sub- stantial amounts of dirt removed from the airstream. Use of these bags will ensure a clean environment throughout the intake stack and prolonged life of the ceiling diffusion media.

Bag filters are sized nominally in their length and width. If the booth track measures 19.5” x 19.5”, then the correct bag listed is 20” x 20”. Bag filters also have a special depth. The depth describes the length of the pockets. This is an exact size and is usually an even number. There are many other sizes available, and custom sizes can be made to order. There are also other efficiencies ranging from 45% through 95%. For additional sizes, UL Ratings or efficiencies, please contact customer service.
