Benefits & Features

Designed to Improve Indoor Air Quality

VariCel® I 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® I media is manufactured with two layers of glass fibres, coarser fibres on the air-entering side and finer fibres on the air-leaving side. Our dual density design allows dirt particles to be collected throughout the entire depth of the filter, utilising the full cleaning potential of the media. Maximum dust holding capacity extends the life of the filter, minimising operating costs. The water-resistant media can withstand intermittent exposure to water, making VariCel® I filters ideal for installations in humid areas, or where the filters are exposed to moisture.

Type SH Single Header

VariCel® I filters are designed for systems supplied by AAF International. A unique 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® I filters are designed to upgrade air cleaning performance and reliability. Flanged headers make the filters compatible with the holding frames and latching devices of various manufacturers, including rear access systems.

Built Rugged for Dependable Performance

VariCel I's rigid construction with supported pleat media pack maintains a compact, unitised structure even under tough operating conditions. Variable air velocity and repeated fan shutdown do not compromise performance.

Unitised Construction

Interlocked header and cell sides, along the entire length of each side, provide maximum sealing. Competitor 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 minimise 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.

Galvanised steel headers and cell sides resist damage during shipping and handling, and prevent corrosion over long service life (HT VariCel® filters are constructed of aluminised steel).

Easy Installation

Rigid construction and minimum depth make VariCel® I filters easy to install in all types of systems.

Options

VariCel® I filters can be ordered with faceguards made of flattened, expanded, galvanised or aluminised 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.

Single Header VariCel® I filters, designed for other manufacturers' equipment, are also available.
