MicroMAX Minipleat Filter
Compared with most competitive filters, which are
packaged only one-per-carton, MicroMAX filters are
packaged three-per-carton. This multiple packaging
means substantial reductions in shipping costs.
The Koch MicroMAX is an extended surface minipleat filter designed for use in a wide variety of
air filtration systems. The MicroMAX offers a unique combination of high efficiency and low pressure drop
making it the ideal filter for use in any standard HVAC system.
The added advantages of its compact 4" depth and lightweight-yet-rigid construction also give the
MicroMAX unsurpassed capability to perform in more specialized and difficult applications.

Paint Spray Booths
MicroMAX filters contain 120sq. ft. of media, yet
they are only 4" deep, and weigh just 7 lbs. each.
Most competitive 12"deep filters with equal media
area require three times the storage space, and
weigh as much 25 lbs. each.
MicroMAX Construction
Minipleat design offers 120sq.ft. of media in
a 24"x 24"x 4" frame for high dust holding
capacity and extended filter lifecycles.
Available with double-walled, moisture resistant,
beverage board frame (completely incinerable)
or galvanized steel frame. MicroMAX with galvanized
frames are offered with peripheral header (model FM)
or no header (model NHM).
Minipleat configuration provides high
efficiency and lower pressure drop.
Die-cut supports are bonded to media
pack for rigidity.
Specially-formulated adhesive bead insures
even airflow and filter strength.
Media pack is completely sealed within
the frame to eliminate air bypass.
Dual Density Filter Media
The media used in MicroMAX minipleat filters is composed of
microfiberglass paper, treated with a specially-formulated, waterrepellent binder. Millions of fibers are constructed into a Graded
Density mat, with coarse fibers upstream and finer fibers on the
air-exiting side. This dual-density insures full media utilization,
which results in higher dust holding capacity and extended filter life.
Also available with antimicrobial-treated media
Adhesive bead separators uniformly secure the
pleats to allow maximum air flow with minimal
pressure drop.
