AMERICAN AIR FILTER INTERNATIONAL

High Purity (HEPA) Filtration

Box Filters

AAF pioneered the modern high-efficiency box filter, and our commitment to innovation in this category continues with our HEPA box filters for demanding applications. Your choice of filter media and advanced separator designs helps you meet stringent requirements for contamination control. Low initial pressure drop, along with high particulate filtration efficiency, can help you control operational expenses.

Individually tested and certified, these HEPA filters are designed to meet demanding contamination control requirements in critical applications. PureForm® separatorless media provides longer life in harsh environments where standard aluminum separators may not last. Of the two filtration options, Alpha 2000 filters offer higher airflow capacity with lower resistance for reduced energy costs.
The AstroCel I HEPA filter is ideal for many critical applications, including cleanrooms and other areas requiring the highest levels of contamination control. It’s available in a wide variety of cell sides, efficiencies and sealing methods.
These Type E filters are designed, constructed and tested to meet strict military specifications for applications where HEPA solutions are intended for biological use. This includes systems involving toxic chemical, carcinogenic, radiogenic or hazardous biological particulates.
From hospitals and pharmaceutical environments to food production facilities and manufacturing plants, all with stringent clean air requirements, HEPA filters can be an effective part of an air optimization solution. These filters are Type A or Type C, which means they are designed, constructed and individually tested and certified to meet customer requirements for resistance and efficiency (penetration) at the filter’s nominal rated capacity.
The MEGAcel I eFRM is our highest performing HEPA filter. It’s designed to be an industry leader, made with AAF’s expanded FluoroResin Membrane (eFRM) media and innovative tapered aluminum separator design. These filters help optimize system efficiency and integrity while minimizing operational expenses in the most demanding applications.
Nuclear facilities require strong filter performance in wet or dry conditions. That’s why these filters use a glass medium that’s composed of boron silicate microfiber. The filters are classified as Type B, which means they are designed and tested to meet the requirements of the American Society of Mechanical Engineers (ASME) AG-1 Code on Nuclear Air and Gas Treatment Section FC.
