American Air Filter introduced the VariCel 2+ filter line. Utilizing AAF’s Impress1 pleating technology, VariCel 2+ filters combine low resistance with high mechanical strength, while maximizing energy efficiency.
AAF’s Impress Technology is a patented pleat formation process that employs embossed media to form the 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.
Impress Technology pleat formation gives the VariCel 2+ filter significant burst strength. 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 particulate from bypassing the filter media. The pleat formation, plastic frame and center 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 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.
