AAF invented the bag-style filter and has continued innovating ever since. Today, thanks to several patented systems, our bag filters provide improved efficiency, long-lasting filtration and easy installation. The filters are designed to remove airborne particulates and tested to meet strict standards of performance. Options are available for a wide range of environments, from mining and industrial applications to healthcare and hospitality.

The first high-efficiency box filter was invented — by AAF — 60 years ago. Today we’ve advanced these filters to provide a high level of protection in a small footprint. These box filters can reduce fine contaminants in critical applications and protect against small particles that carry viruses and bacteria. The space-saving design helps reduce costs of shipping, storage and handling.

AAF uses durable, heat-resistant materials in filters specially designed for high-temperature environments. These filters remove airborne contaminants to protect processes that use hot air, including food processing and photography. Components are made of materials that stand up to high temperatures. Mechanical interlocking means no glues or sealants are needed. The result is filtration performance that’s resistant to damage and degradation.

Synthetic filtration media is often needed or preferred. An intricate fiber structure can hold more dirt with less resistance. AAF offers a range of media in pads and rolls designed to remove contaminants in critical environments — from schools and universities to paint spraying booths and weaving rooms.

AAF has developed panel filters suited for many commercial environments. Disposable filters are economical and easy to install for commercial buildings. Washable and reusable filters are simple to maintain and stand up to use in conditions where high temperatures and moisture are a concern. These filters offer many options, including a choice of media and frame materials and special sizes.

Filtration media is pleated to increase the surface area and density of a filter, giving it more room to reduce airborne contaminants. The result is a filter designed to last longer and reduce maintenance. AAF filters offering low initial resistance and high capacity for holding dust can reduce energy usage to control operating costs. Options are available to remove contaminants everywhere from pharmaceutical and healthcare facilities to agriculture and firing ranges.

AAF offers V-Bank filters that extend the surface area of a standard filter without increasing the filter size. High dust-holding capacity allows a longer filter life to reduce maintenance time and cost. Our V-bank filters are suitable for many applications, including green building projects.
