Exclusive Media Design Provides Cleaner Air and Longer Service Life
More Media Surface Area“5700” filter media contains substantially more glass fibers per square foot than standard filters. More fibers provide greater surface area to catch large quantities of dirt particles. These fibers also significantly reduce the initial resistance.
Progressive Density Media ConstructionThis unique construction enables “5700” filters to hold more dirt throughout the entire depth of the media. The fibers on the air-entering side are interlaced with a more open pattern, which becomes progressively tighter towards the air-leaving side.
When the media is clean, dirt particles penetrate deeper before being trapped. As the back of the media loads, particles are caught progressively closer to the air-entering surface. This exclusive media design eliminates face loading and increases both arrestance (air cleaning capability) and dust-holding capacity (service life).
The glass fibers are heavily coated with AAF Flanders’ exclusive Viscosine adhesive. The wicking action of the highly viscous adhesive enables it to cling to the fibers and thoroughly saturate each dirt particle. This means accumulated dirt will not break away and blow downstream.Viscosine adhesive maintains its dirt-trapping characteristic over the life of the filter. It is also non-toxic, flame-retardant, odorless, and completely safe to handle.
High Compression Strength
“5700” filter media is treated with AAF Flanders’ specially formulated thermoset resin, which forms a strong bond at each point where fibers intersect, resisting compression in the air stream. As the dirt load builds and resistance increases, the media maintains its thickness without collapsing or face-loading.
