The 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, can delivers a higher dust holding capacity (DHC) and a lower pressure drop for greater energy efficiency.
The filters are one-third the volume of other high efficiency filters. AAF says that they have low resistance, high mechanical strength, and can maximise energy efficiency.
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 sealed in a water-based copolymer emulsion, keeping particulate from bypassing the filter media.
The 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 suitable for general HVAC and industrial applications, as well as applications operating with variable air volume, turbulent airflow, or high humidity.
