Description
Slim-Line Design Lowers Operating Costs
The slim-line design of the VariCel II filter provides low resistance with maximum dust loading capacity, lowering operating costs. VariCel II filters are made with a minipleat media pack with gluebead separators which allow this filter to have the same amount of media area, in a filter only one-third as deep, as many filters using traditional corrugated aluminum separators and twice the media area of some 12″-deep competitive rigid-style filters using high-loft, fine glass fiber or synthetic media.
The minipleat media pack maintains even pleat spacing as the dust load builds, even during turbulent airflow. Media pack support retainers, built into the die-cut frame, are bonded to the pleat tips to further secure pleat spacing. Consistent pleat spacing provides even distribution of airflow throughout the entire face of the filter, resulting in lower resistance, full use of the entire depth of the media, and higher dust loading capacity.
This Slim-line mini-pleat design enables four VariCel II filters to be shipped in a carton only 16 inches high, compared to most competitive filters, which are shipped only one per carton. Shipping costs and storage space are significantly reduced. The thinner depth and fiberboard frame also make disposal easier and significantly reduce the contribution to landfills. With no metal components, they are also suitable for incineration.
Dual Density Media Increases Dust Holding Capacity
VariCel II filter media is made of microglass paper with a water repellent binder. The fibers are formed with dual density construction, consisting of coarser fibers on the air-entering side and finer fibers on the air-leaving side. This allows particles to be collected throughout the full thickness of the media, substantially increasing dust holding capacity. The media can withstand intermittent exposure to water without affecting filter performance.
Unitized Construction Adds Strength, Prevents Leakage
The frame is made with a 2-piece die-cut constructed from high wet-strength beverage carrier board. Two mating die-cut boxes are bonded together, forming a double wall around the perimeter of the filter. The mini-pleat media pack is bonded inside the double wall. The double-walled frame prevents leakage and increases rigidity.
Indoor Air Quality
VariCel II filters are available in MERV 11, 13 and 14 efficiencies, and the 4″ deep frame allows this filter to be used for upgrading efficiency even in areas with limited space to add filters. Additionally, MERV 14 VariCel II filters are available with antimicrobial which is designed specifically to improve Indoor Air Quality (IAQ). Air filters trap and concentrate particulate air contaminants, which can include fungal and bacterial spores. The presence of antimicrobial in the filter media is intended to preserve the integrity of the media through the useful life of the filter and prevent “grow-through” of any microbe collected by the filter. Note that 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
