Construction

Filter frames are constructed from two pieces of die-cut, moisture-resistant carrier board. Components “t le- scope” into one another and provide double-wall construction and a p eci- sion fit. The frame includes diagonal and horizontal supp rt members bonded to the media on the air enter- ing and leaving sides for unsurpassed frame strength. Locking corners and positive media-to-frame seal reduces the possibility of air bypa .

The filter media is a high-loft, rein- forced, non-woven cotton/synthetic blend. It is ontinuously laminated to an expanded metal grid on the air leaving side to provide pleat stability throughout the life of the filters and prevent media flutter while in opera- tion.

Flanders’ unique v-pleat wedge pleat allows for total media usage and pro- vides maximum air flow and dust hold- ing capacity.

Principles of Operation

Flanders’ v-pleat design insures that the greatest media area is exposed to the air flow to promote uniform dust loading. Competitive filters cannot m int in this rigid shape and tend to flatten out, using only a por- tion of the media. This v-pleat design cre tes n air exit area (B) equal to the air entering area (A), which minimizes end losses and reduces pressure drop.

Radial wedge pleats have unequal air exit (D) and air entering (C) areas, which cause higher resistance and uneven use of media.
