Next to solid and liquid particles, gaseous contaminants are a significant contributor to air pollution and can have a big impact on human health and process performance. Gaseous contaminants can arise from many different sources; from odorous sources (like waste treatment facilities or restaurants), corrosive sources (like industry emissions or cleanroom chemicals) or toxic sources.

With the increased focus on the health impact of air pollution, achieving an optimal Indoor Air Quality (IAQ) is extremely important. The European EN 13779:2007 standard for ventilation and room conditioning systems in non-residential buildings recommends gas-phase filtration solutions for achieving the best IAQ when the outdoor air is highly polluted. For effective removal of these gaseous contaminants, the gas-phase filtration products of AAF have proven to offer the right solution.

Under the SAAF™ brand, AAF offers a broad portfolio of gas-phase filtration solutions that can be used for multiple applications: from IAQ and Corrosion Control to Odour Control. It can be composed of several options in media, delivery systems and equipment. Which combination to use will depend on the application needs, the target contaminants to filter and their concentration levels. The SAAF™ gas-phase filtration products can be combined with AAF’s particulate filtration solutions to create a Total Clean Air Solution. Your local AAF sales office can advise and support you in choosing the most effective solution.
    

	Media SAAF™ Media provide high efficiency filtration for effective removal of airborne molecular contaminants encountered in nuclear contamination, bio-hazard contamination and chemical (gas) contaminated air streams. AAF offers an extensive range of both gas-specific and custom blended media.
	Delivery Systems SAAF™ Delivery Systems assure that gaseous contaminants are effectively filtered in combination with the appropriate SAAF™ Media. The offer consists of Cassettes, Canisters, Pleated Filters and Compact Filters that hold the SAAF™ Media.
	Equipment SAAF™ Equipment provides the best solution for total protection from particulate and gaseous hazards. The equipment options vary from Deep Bed Scrubbers (DBS), PORTA-Scrubbers and Air Purification Systems (APS) to Side Access Housings (SAH) and Front Access Housings (FAH) in which complete cassettes with pre-filled media can be placed together with pre- and final particulate filters from AAF.
	Support Tools For being able to effectively filter gaseous contaminants from the air for any specific application, AAF offers several effective and easy to use supporting tools. This varies from SAAF™ Tech Tools to SAAF™ Detect and SAAF™ Reactivity Monitoring Coupons (RMC).
