Type SH
Single Header VariCel filters are designed for systems originally supplied by AAF International. A unique 13/16″ flanged header on the air entering side allows the filter, to be easily inserted and latched into front and side access systems.
|
|
|
Type DH
Double Header VariCel filters are designed to upgrade air cleaning performance and reliability. Two 13/16″ thick flanged headers make the filters
compatible with the holding frames and latching devices of various manufacturers,including rear access systems.
XL Series
VariCel filters, single header (XL-S) and double header (XL-D), contain up to 67% more media and offer more than twice the service life of standard
single and double header models.

High Temp Series
VariCel filters are designed for systems operating from 350º-900ºF. Constructed of aluminized steel, High Temperature VariCel filters offer rated efficiency with proven reliability over the life of the filter. See page 4 for models and temperature limits. Type NH Series VariCel filters are designed for special sizes and applications, including incineration and compaction disposal systems. Manufactured of fire-retardant, 3/4″ thick, heavy wall particle board, Type NH VariCel filters (U.L. Class 1) are operable at temperatures up to 200ºF. The filters are constructed without headers and cell sides are flush with front face dimensions.

Prefilters Can Double VariCel® Life
Using prefilters, such AAF’s PerfectPleat® pleated filters or “5700” panel filters, will greatly extend the life of VariCel filters.
Dual Density Media Reduces Operating Cost
VariCel media is manufactured with two layers of glass fibers coarser fibers on the air entering side, and finer fibers on the air leaving side. Our dual density design allows dirt particles to be
collected throughout the entire depth of the filter utilizing the full cleaning potential of the media. Maximum dust holding capacity extends the life of the filter, minimizing operating costs. The
water resistant media can with stand intermittent exposure to water, making VariCel filters ideal for installations in humid areas or where the filters are exposed to moisture.
Unitized Construction
lnterlocked header and cell sides provide maximum sealing. Competitive filters are designed with loose fitting headers which allow greater potential for bypass leakage.
