Multi-Cell HT for High Temperature Applications
Multi-Cell HT filters are constructed with aluminized steel frames designed for operation
in applications with temperatures ranging from 350° to 900°, and are ideal for use in
paint ovens where high temperatures may cause galvanized steel to scale or flake. Each
filter has aluminized steel faceguards on both sides to protect the media against damage
in shipping, handling, and actual operation. Two standard sizes, 24x24x12 and 12x24x12,
are available in two efficiencies, 90-95% and 60-65%. The media used in all HT filters is
the same type used in standard Multi-Cells. The media pack (which consists of nonflammable
glass fiber media and aluminum separators) is secured within the frame by a special
sealant which contains no silicone or other component which may be harmful to the painting
process.
DuraMAX V-Style
Minipleat Filter
The DuraMAX is a rigid, extended surface air filter, engineered to provide maximum
performance and prolonged filter life cycles, even in the most difficult environments. The
durable, rugged, construction of the DuraMAX make it the filter of choice in filtration
systems with high velocities or variable air volumes. DuraMAX Filters are constructed with
a 100% plastic frame and are completely incinerable.
DuraMAX provides an unequaled combination of low pressure drop
and high efficiency through the use of our unique minipleat design. This high capacity
minipleat design allows a nominal 24x24x12 filter to incorporate 194 square feet of filter
media. This increased extension of the media surface area insures low pressure drop, and
low resistance to airflow means lower energy costs to the user.
Another benefit of the increased media area is extremely high
Dust Holding Capacity, which significantly prolongs the service life of the filter. Fewer
filter changes translate into substantially reduced maintenance and disposal costs.
In order to meet the wide range of requirements found in today's
complex air filtration systems, DuraMAX filters are available in five ASHRAE efficiencies,
65, 75, 85, 95, and 98%. The Filter is offered in three standard sizes, 24x24x12,
20x24x12, and 12x24x12. Single or double header configurations are available.

DuraMAX 2v High Efficiency Minipleat Filter
The DuraMAX 2v is an extended surface air filter engineered to provide maximum performance
and prolonged filter lifecycles in office buildings, hospitals, paint booths and all types
of commercial and industrial HVAC applications. The DuraMAX 2v is completely incinerable
after use. What makes the DuraMAX 2v unique and different? The new 2v design offers all
the benefits of our other high performance minipleat filters, but contains approximately
110 ft2 of filter media. The reduced media area makes the 2v model an economical
alternative in applications where a minipleat filter is desired but initial purchase price
is of utmost concern.

Duo-Cube Extended Surface Synthetic Media Filters
Koch Duo-Cube filters are medium efficiency, extended surface filters constructed of 100%
synthetic fibers. In order to meet the requirements found in various air handling systems,
Duo-Cubes are offered in three styles; Standard, Self-Seal, and 3 Ply. All three designs
are engineered to provide an excellent combination of efficiency and extended filter life
cycles. Standard Duo-Cube: * Fits existing cube-type baskets with no modification to
equipment. * Scrim backing provides durability and rigidity. * Constructed with 100%
progressively dense synthetic media. * Superior dust holding capacity provides long filter
life.
Fiberglass
Air Filter Media Rolls and Pads
Koch Supergrade Fiberglass Air Filter Media is available in a wide range of pad and roll
sizes. Because all air filtration systems are different, one standard media cannot meet
every requirement. With three media depths to choose from it is possible to find the right
media for any fiberglass application. Contact your Koch representative for recommendations
on your system.
Automatic Roll
Filters
Koch Automatic Rolls are available in two grades of glass fiber media (GD, GHD), and three
grades of synthetic media (P, ST, and MD). All five styles consist of progressively dense
media and adhesive to enhance dust holding capacity. A full-width integral scrim backing
on every roll provides protection against "necking" and fiber break-off. Koch
Automatic Rolls are available with cores to fit, without modification, all popular brands
of original equipment including AAF, Farr, BLC, Continental and many others.
MicroSafe
Antimicrobial-Treated Air Filters
The filter media utilized in all MicroSafe products is treated with a highly specialized
antimicrobial agent designed to effectively control microbial growth, such as mold,
fungus, mildew, and bacteria, on contact. This capability to control such a wide range of
micro-organisms makes the MicroSafe line an excellent frontline barrier in the effort to
achieve improved Indoor Air Quality (IAQ).
Utilizing recently-developed technology, MicroSafe Antimicrobial
Air Filters offer a unique and unparalleled combination of microbial abatement and high
efficiency particulate filtration.
Applications: MicroSafe Antimicrobial Air Filters are designed
for use in any HVAC system, and are ideal for control of micro-organisms in hospitals,
nursing homes, laboratories, and commercial buildings of all types.
Commercial and Industrial Disposable Panel Filters
Koch Commercial & Industrial Disposable Panels are economical air filters designed for
light-to-medium duty air filtration applications. Koch C&I Disposables are constructed
for high performance and durability:
Fiberglass Media - Standard C&I Disposables are constructed
with high grade progressively dense glass fibers. The air entry side is composed of open
coarse fibers, while the air exit side is made up of tighter fibers. This dual density
media configuration allows for proper depth loading and full utilization of the filter
media. Each fiber is coated with a non-migrating adhesive to enhance filter performance.
Polyester Media - C&I Disposables are also available with
optional polyester filter media, a dual-layered high performance media for applications
where synthetic filter media is specified.
Multi-Test
Replacement Cartridge
Multi-Test Filters are extended surface high efficiency air filters designed to fit the
basket framework of the Farr HP* without modification. MT Filters are collapsible
replacement cartridges, and are available in four nominal efficiency ranges: 20-30%,
45-55%, 80-90%, 90-95%.
Pad Holding
Frames
Koch Pad Holding Frames are designed for quick and easy filter changes. Sturdy 24 gauge
frame construction and 10 gauge hinged-gate make the Koch Pad Frame the ultimate design
for frame-and-pad installations.
Type AR
Filter Holding Frames
Type AR Filter Holding Frames are designed for simple and cost effective construction of
filter banks. 16 gauge galvanized steel components insure years of reliable usage and make
each Type AR Frame virtually indestructible.
