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.
Variable air
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.
