American Air Filter 220-600-051
Designed for general air filtration applications with light to medium dust loading conditions, StrataDensity
disposable panel filters are engineered for sturdy, economical performance and ease of use. Available in a
wide range of sizes and two thickness configurations, StrataDensity filters are used in all types of HVAC
systems to protect the coils from dirt. They are also used as prefilters to extend the life of higher efficiency
INDUSTRY'S LEADING COMMERCIAL DISPOSABLE PANEL FILTERS
StrataDensity filters are constructed with AAF manufactured premium grade fiberglass media. More fibers
ensure StrataDensity filters have higher arrestance and clean air better than competitive filters.
High Dust Holding Capacity
The media is coated with a light adhesive to increase the amount of dirt the filters canhold. Higher dust
holding capacity means longer service life and lower operating costs

STURDY CONSTRUCTION, LONGER FILTER LIFE
Compression Resistant, Double-Skinned Media
The double-skinned media design eliminates the need for scrim or metal retainers by building the strength
requirements into the fiberglass. Through the use of computer automation, the fibers can now be spun in a
pattern that actually duplicates the holding strength of scrim type retainers. The double-skinned fiberglass
retainer also provides a better adhesive bond to the frame because it is spun into the media. This new
technology has produced a superior product without additional cost.
Compression resistant glass fibers decrease media pad deterioration allowing a normal rise in resistance as
the filter collects dirt particles. A slower rise in resistance extends the life of the filter.
A continuous adhesive bond between the media pad and chipboard frame maximizes construction strength
to reduce handling damage and permit longer storage life.
DESIGNED FOR EASY HANDLING AND DISPOSAL
The chipboard filter frame, free of sharp edges, makes the panel easy to install and remove. After removal,
the filter can be safely folded for compact disposal.
