For clean rooms and high purity applications. Minipleat design ensures low resistance to airflow. Compact, lightweight extreuded aluminum cell sides. Gasket seal. 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. 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. Each minipleat pack is sealed into the filter frame with a white urethane adhesive, which is designed specifically for high efficiency air filtration. 99.99% on 0.3 microns.
