Precisionaire 425t Panel User Manual

425T Panel  
4-Ply Polyester Panel Filter  
For use as a pre-filter  
The 425T panels are manufactured from  
two distinct 100% resin bonded polyester  
media layers with a wire support frame  
sealed between the two layers. This  
provides a self-supportive, self-sealing  
panel filter which significantly decreases  
air bypass when installed in the entire fil-  
ter track.  
The first layer is a 1.5” polyester media  
which uses 45 denier polyester fibers  
with an open weave on the entry side, 15  
denier fibers with slightly tighter weave in  
the middle, and 6 denier fibers with an  
even tighter weave on the downstream  
side. This triple denier entry media com-  
bination provides three stages of filtration against particulate. The downstream side of  
the media is treated with a special non-migrating tackifier which significantly increases  
the filter’s efficiency. The second media layer is made from 6 denier polyester fibers  
heavily needled to a dense 1/4” depth. This adds a final layer of defense against  
small particulate.  
The progressive density media structure is what makes the 325T panel so effective.  
The particles are “funneled” out of the airstream. Large particles are captured on the  
outer layer and finer particles are captured in the second and third layers.
