BIO HEPA Filters

  • Low Resistance to airflow 140-560 L/sec/Module
  • Classified H11 (EN1822)
  • Constructed to withstand High Temperatures - 150 DC
  • 95% Efficiency to 0.3 Micron Particles

Bio High Efficiency Particulate Air Filters are for use in semi-critical locations. The filter media is constructed from corrugated aluminium separators, which divides the sub-micron glass fibre's formed into high density media paper. This media is pleated to provide a high ratio of media area to face area, resulting in low media velocity, which is essential for Ultra High Efficiency Filtration. Gasket seals are provided to prevent any air or leakage bypass. Installation of the Bio Hepa's are to be in designed permanent mounting frames or modules and clamps are usually used to seal the HEPA and mounting frame as one. Pre-Filters can be used to extend the life of the high performing final filter.


Used mainly in Cleanrooms with semi-critical functions,  Food Industry, Pharmaceutical, Hospitals, Industrial Cleanrooms etc.
