American Air Filter Co., Inc. d/b/a AAF International, manufacturer of AmericanAirFilter® and AAF® products, announced the introduction of the VariCel 2+ filter line. Utilising AAF’s exclusive Impress* Pleating Technology, VariCel 2+ filters combine the lowest resistance with high mechanical strength, while maximising energy efficiency. This combination provides valuable overall operating cost savings.
AAF’s Impress Technology is a patented pleat formation process that employs embossed media to form the optimal pleat geometry. This combined with less restriction from separator material and better media usage delivers a higher dust holding capacity (DHC) and a lower pressure drop for greater energy efficiency. VariCel 2+ filters utilise this exclusive pleating technology, to make the most energy efficient 4-inch filters available.
Higher DHC equates to a longer service life, reducing the number of filter changes, saving both labour and material costs while reducing waste. In addition, VariCel 2+ filters are only one-third the volume of other high efficiency filters, significantly reducing the contribution to landfill waste, shipping costs and storage space.
Impress Technology pleat formation delivers a robust media pack, giving the VariCel 2+ filter a burst strength that exceeds the standard seen in the industry. VariCel 2+ media is moisture resistant and can withstand intermittent exposure to water without affecting filter performance. The media pack is encased in a high impact plastic frame and completely sealed in a water-based copolymer emulsion, keeping particulates from bypassing the filter media. The pleat formation, plastic frame and centre support bar make the VariCel 2+ filter mechanically stable, providing high performance even in tough operating conditions.
VariCel 2+ filters are available in High Capacity (HC) and Standard Capacity (SC) models and are available in three efficiencies: MERV 15, MERV 14 and MERV 11. VariCel 2+ filters are appropriate for general HVAC and industrial applications, as well as applications operating with variable air volume, turbulent airflow or high humidity. Engineered for a variety of applications, the VariCel 2+ filter is an easy upgrade from standard 4-inch pleated filters when higher efficiency and longer life are desired.
