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.

AAF offers High Efficiency Gas Adsorber (HEGA) filtration to filter gaseous contaminants from airstreams through a process of adsorption. Typically used by the nuclear industry, HEGA systems are often installed in a walk-in bank. The HEGA system’s adsorber must be able to provide a 99.9% minimum mechanical efficiency.

AAF understands the critical environments that require HEPA/ULPA filtration. That’s why we individually factory test each of these high-quality filters we manufacture. Our HEPA (High Efficiency Particulate Air) and ULPA (Ultra Low Penetration Air) filters are available in highly customizable systems to help protect people and processes from airborne particulates. A variety of cell sides, efficiencies and sealing methods allows a solution suitable for cleanrooms and similar environments.

AAF has designed a range of high-performance filters to stand up to extreme temperatures in demanding environments such as pharmaceutical, microelectronics and life science applications. Superior ramp speed enhances production efficiency, and these filters maintain performance even after repeated cycling.

AAF offers a portable system that’s easy to use for improving air quality in areas such as classrooms and healthcare facilities. High-efficiency, two-phase filtration can be configured for recirculation or exhaust. An advanced interface provides control over clean air, particulate levels and noise.

AAF makes it possible to reduce energy and operating costs associated with HEPA filtration in high-airflow applications. The system features an ultra-low pressure drop along with an extended media area that’s larger than even high-capacity, traditional HEPA filters. This helps extend the life of the filters so they can go longer before they’re changed out.
