Minipleat HEPA Filters for Clean Rooms and High Purity Applications
  • Minipleat design ensures low resistance to airflow
  • Compact, lightweight extruded aluminum cell sides (CS models)
  • Gasket or gel seal
  • Multiple efficiency options

Koch Filter’s BioMAX CS uses a compact minipleat HEPA filter that is designed to meet the stringent requirements of today’s clean room applications. Engineered to provide the optimum combination of efficiency and airflow, these filters can be used in a wide range of applications, including pharmaceutical facilities, hospitals, biotech laboratories and other environments where control and removal of airborne contaminants is paramount.

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.

Gel Seal
  • Constructed with a built-in channel in the filter frame which contains a non-flowing, non-hardening urethane gel sealant
  • Designed for framing systems and housings equipped with a “knife edge” seal
  • BioMAX CS with Gel Seal is available with cell side (filter frame) depths of 4 3/4”
