KKM
Washable Permanent Filters
Galvanized Model # 50055 and Aluminum Model # 51255
Flanders Model KKM is a heavy duty, washable, aluminum media, all metal filter.
KKM is suitable for all residential and commercial applications.
The KKM offers large filtering area, high dust holding capacity, uniform loading
and low resistance to air flow. It is recommended that the filter media be coated
with dust adhesive for optimum performance.
Construction
The KKM filter has a rugged galvanized steel frame that encloses the bonded
expanded aluminum mesh media. The corners are mitered and the frame is
secured with pop rivet(s). The KKM has drain holes in three corners.
The bonded aluminum media is slit and expanded to several different size open-
ings. This design allows contaminants to be trapped throughout the entire filter
depth and not just at the surface. The media is retained within the frame by
expanded galvanized steel.
An all-aluminum version of the KKM is also offered, which has an aluminum frame
and is constructed with expanded aluminum retainers.
The standard offering of KKM filters includes six of the most popular face sizes in
1” and 2” depths. Special face sizes and 1/2” depth filters are also available. For
ease of installation, all filters are undercut slightly on length, width and depth.
Filter Coating and Cleaning
The KKM performs best as an impingement type filter. Optimum performance
requires use of a dust adhesive on the media. Flanders offers Kwik Kut Filter
Spray and Filter Boost.
Wash with a mild detergent and rinse to remove collected dust.
