Poly Shield XI 3-Ply Panel Filter

poly shield XI panel filter

Panel Specifications Panel shall be a distinct 3-ply design comprised of polyester fibers. The air leaving side shall be purple in color and contain a non-migratory, non-drying, Dustlok composite adhesive coating all downstream fibers.

An internal 9-gauge support grid with up to two cross wires seals the panel in place, preventing fluttering and dirt bypass. Media shall contain Spor-Ax antimicrobial which effectively controls microbial growth on the filter, media.

One panel delivers 3-stages of filtration. First stage designed for depth-loading; second stage captures particulate and keeps it from filtering through the media; third stage, Dustlok composite adhesive, absorbs particles and continuously renews its effectiveness.

Media shall be MERV 11 in accordance with ASHRAE 52.2-2012.
