K-Trac
Modular Filter Framing System
See model number development method on next page.
Important Features
• Provides substantial savings in field assembly
• Filters are tightly sealed to eliminate air bypass
• Filters can be replaced quickly and easily
• Modules are factory-engineered with built-in stiff-
ening
• Construction is corrosion-resistant aluminum
General
K-Trac Filter Framing Modules are used for
ASHRAE rated filters 2” to 36” in depth. K-Trac
Modules are complete factory-designed units which
replace multiple field-erected holding frames. They
also provide inherent structural strength and leak-
proof assembly that is sometimes lacking in frame-
type installations.
K-Trac framing members are factory-cut to length,
pre-drilled and gasketed for easy and quick assem-
bly. Simple tools and light labor are all that are
required. Filters are easily inserted or removed and
require no clips or fasteners. Filters are angled into
the upper track, then set into the lower track.
Versatility
K-Trac Filter Framing Modules are available in
sizes up to a nominal 12 ft. high and 14 ft. wide for
upstream or downstream service. Modules may be
joined for larger banks. The 2” prefilter track
accepts disposable or pleated prefilters for single-
stage applications.
The primary filter track accommodates Precision
Pak bag filters, Superflow V, or Rigid-Air filters, or
other filters having nominal 1” thick headers.
Construction
K-Trac framing members are constructed of Type
6063-T5 mill-finish extruded aluminum. Clear
anodizing is available as an option. Prefilter and
primary filter tracks are factory-gasketed at the top
and bottom with polypropylene pile air seals.
Side-to-side gasketing is furnished on the filter
headers with every change. Side gaskets are com-
pressed by a positive-sealing spring-loaded com-
pression bar actuated by a sealing lever. The com-
pression bar is retracted when loading or unloading
filter elements.
Modules 8 ft. wide include one vertical support for
the upstream side. Wider modules are furnished
with vertical supports on the upstream and down-
stream sides. Sealing levers are located on the left
side of each horizontal row when facing in the
direction of air flow unless specified otherwise.
