    • Compact Minipleat Design Saves Energy
      BioMAX CS filters are manufactured with a specialized thermoplastic adhesive bead (no aluminum separators) to maintain proper pleat separation and full utilization of the filter media. Precise spacing of glue-bead separators ensure low resistance to airflow and reduced energy costs.
    • Multiple Efficiency Options
      Each minipleat pack is sealed into the filter frame with a white urethane adhesive, which is designed specifically for high efficiency air filtration. BioMAX CS and V2000 filters are available in multiple efficiencies: 99.97%, 99.99%, and 99.999% on 0.3 microns.
    • Cell Sides are Engineered to Fit Any Existing Housing
      Cell sides (filter frames) for the BioMAX CS are constructed of heavy-duty anodized extruded aluminum. The extruded aluminum cell sides are available in several configurations to fit any existing frame system or air filter housing: gasket seal, gel seal, reverse gel seal, and others. BioMAX V2000 cell sides are constructed of heavy-duty sheet aluminum.
