Designed to Improve Indoor Air Quality
VariCel filters with antimicrobial are designed specifically to improve Indoor Air Quality (IAQ). Air filters are designed to trap and concentrate particulate air contaminants, including viable fungal and bacterial spores. The presence of antimicrobial preservative in the filter media is intended to preserve the integrity of the media throughout the useful life of the filter. Antimicrobial preservatives are not meant to increase the efficiency of the filter, nor to kill microorganisms “on the fly” as they pass through a filter. Antimicrobial is EPA registered and environmentally safe.
Dual-Density Media Reduces Operating Costs
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 withstand intermittent exposure to water, making VariCel filters ideal for installations in humid areas, or where the filters are exposed to moisture.
Type SH Single Header
VariCel filters are designed for systems supplied by AAF Flanders. 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.
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. XL Series VariCel filters are offered in a 12″ depth, MERV 14 and MERV 11.
Type HT (High Temperature) Series
VariCel filters are designed for systems operating from 350°-900°F. Constructed of aluminized steel, HT VariCel filters offer rated efficiency with proven reliability over the life of the filter. HT VariCel filters are offered in a 12″ depth, MERV 14 and MERV 11.
Type NH Series
VariCel filters are designed for special sizes and applications, including incineration and compaction disposal systems. Manufactured of fire retardant, ¾″-thick, heavy wall particle board, Type NH VariCel filters are UL Classified and are operable at temperatures up to 200°F. The filters are constructed without headers, and cell sides are flush with front face dimensions.
Built Rugged for Dependable Performance
VariCel's rigid construction with supported pleat media pack maintains a compact, unitized structure even under tough operating conditions. Variable air velocity and repeated fan shut-down do not compromise performance.
Interlocked header and cell sides, along the entire length of each side, provide maximum sealing. Competitive filters are designed with loose fitting headers, which allow greater potential for bypass leakage.
Pleats and Separators Bonded for Strength
During the pleating process, spots of glue are applied to bond each separator to the adjacent pleat. This solidifies the media pack to minimize movement and prevent media damage. Burst strength is increased to prevent the filter from blowing out under variable air volume conditions or unusually high resistance.
Galvanized steel headers and cell sides resist damage during shipping and handling, and prevent corrosion over long service life (HT VariCel filters are constructed of aluminized steel).
Rigid construction and minimum depth make VariCel filters easy to install in all types of systems.
VariCel filters can be ordered with faceguards made of flattened, expanded, galvanized, or aluminized steel on one or both sides of the filter.
Factory-installed gaskets are available on the front or back of the header.
Vinyl coated separators are available for corrosive conditions.
1⅛″ Single Header VariCel filters, designed for other manufacturers' equipment, are also available.
