Applications
Gas-Phase Filtration SolutionsQuick Guide on capabilities, systems and applicationsfor the removal of gaseous contaminants.
AAF has the expertise to custom design the right gas-phase solution for the specific application needs. Which system will be the most suitable will depend on the application characteristics, the target contaminants to filter and their concentration levels. There is no standard answer,
as each situation is unique. Your local AAF sales office can advise and support you in choosing the most effective solution with the right chemical media, delivery systems and equipment.
The Right AAF Gas-Phase System
Achieving a high level of Indoor Air Quality is important for human health and for the preservation of valuable objects. In large public areas like airports, schools, museums or hotels, it needs to be assured that people
can always breathe healthy air and that valuable cultural assets remain untouched from hazardous contaminants in the air.
Indoor Air Quality
Museums. With museums often being situated in busy urban environments, controlling gaseous contaminants is a fundamental challenge for protecting priceless collections of artifacts, historical assets, artwork and literature. By maximizing the life of these objects, we essentially protect our heritage.
Damage to collectibles can be caused by gaseous pollutants such as Ozone, Formaldehyde or Sulfur dioxides. Without proper protection, these may lead to adverse health effects on visitors and employees, and premature aging of valuable papers, textiles, photographs and paintings.
Gaseous contaminants can have a big impact on critical processes within applications such as refineries, the micro-electronics and hospitals. Gases in the environment can cause corrosion of important
equipment and process control areas. When not controlled properly, costly repairs and downtimes could be the result.
Corrosion Control
Healthcare. Healthcare equipment and instrumentation in treatment or emergency rooms are major investments for hospitals that need protection from hazardous gaseous contaminants. Areas of concern may be HVAC units, control rooms and electronic instrumentation, diagnostic equipment and x-ray machines.
High-quality gas-phase filtration can reduce corrosive gases, such as Nitrogen dioxide and Sulfur dioxide, in order to protect health care facilities from potential failures caused by corrosion. Not only does it assure a proper functioning of the health care processes with less risk of repairs and downtime, it also directly contributes to the quality of patient treatments.
Odorous gases can arise from many different sources such as restaurants, waste treatment, industrial processes and agriculture. If such
gases are not properly filtered unpleasant odours can persist, causing unpleasantness to employees, visitors and businesses in the area.
Odour Control
Wastewater Treatment. For wastewater treatment facilities, odor control is constantly evolving because of the increasing amount of chemicals used by industries worldwide. Odors are generated in varying degrees throughout a wastewater treatment process.
The main odor-generating areas are pump stations, head works, clarifiers, digesters, aeration basins, lagoons and sludge handling areas. Examples of odors that are associated with these processes include Hydrogen sulfide, Ammonia, Sulfur dioxide and Amines. Effectively eliminating such odorous gases from the air will result in higher health and comfort levels for people in the area.

The need for clean air has never been as prominent as in today’s highly industrialized and densely populated world. The outside air has become increasingly polluted, whereas today’s technologically advanced processes and the increased amount of time that we spend indoor require more advanced clean air solutions than ever before.
Next to 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. For effective removal of these gaseous contaminants, the gas-phase filtration products of AAF offer the right solution.
Already since 1921, AAF has gained significant experience in air filtration by offering a wide variety of
products for removing and controlling both particulates and gaseous contaminants. For reducing or eliminating the gaseous contaminants, AAF has developed the innovative SAAF™ product line. It allows AAF to offer unique and effective gas-phase filtration concepts, tailored to the specific situation. It supports AAF in its ambition to offer best-in-class clean air to the world.
Indoor Air Quality With the increased focus on the health impact of air pollution, achieving an optimal Indoor Air Quality (IAQ) is extremely important. The EN 13779 is the new European standard for ventilation and room conditioning systems in non-residential buildings, and is now a legally accepted standard in all countries of the European Union.
EN 13779 specifies both outdoor air and indoor air quality, resulting in recommendations for particulate and gas-phase filtration. Taking into account the outdoor air conditions, it sets out to achieve a comfortable and healthy indoor air quality in all seasons of the year at acceptable installation and operating costs.
According to EN 13779, the outdoor air is categorized in three levels, from ODA 1 (pure air which may be only temporarily dusty) to ODA 3 (very high concentrations of gaseous pollutants and particulate matter). The indoor air quality, on the other hand, is classified in four levels, from IDA 1 (high indoor air quality) to IDA 4 (low indoor air quality). When the pollution level of the outdoor air is classified, EN 13779 recommends the right air filtration solution for the preferred indoor air quality, as summarized in the table below.
The SAAF™ product line has been developed by AAF to offer effective gas-phase filtration solutions for removing gaseous contaminants from the air. The diversity of its customer’s air filtration requirements has given AAF the expertise to provide products, systems and supporting tools, based on a broad industry perspective. In combination with superior knowledge from a wide scope of applications, customers are guaranteed to receive top quality products, services and results.
SAAF™ Technical ServicesThe SAAF™ Technical Services Group has the instrumentation and training to perform comprehensive evaluations and environmental assessments. All tests are carried out and correlated to applicable standards. Evaluations include particulate contamination assessments, gaseous contaminant assessments, humidity assessments, product life cycle assessments, room integrity verification, and sealing and HVAC circuit checks.
SAAF™ Tech ToolsSAAF™ Tech Tools is the filtration industry’s most sophisticated and complete decision-sciences software for configuring clean air solutions to remove gaseous contaminants. It is used by AAF’s specialists to select appropriate media, delivery systems and equipment options by using the application specific data as input. Based on its thorough experience, AAF is also able to benchmark from a vast library of pre-configured applications and typical concentrations. The end result is a clear, comprehensive and tailor made offer for gas-phase filtration that includes all the details needed for successful project execution.
SAAFDetect™
SAAFDetect™ is a Visual Air Quality Indicator that provides an easy, visual indication of gas presence and an estimate of gas concentrations. It can be used to evaluate the need for gas-phase filtration solutions, estimate existing filter efficiency, or to point toward the need for more analytical methods. Building owners or facility managers can use this tool to perform initial evaluations. The reports state possible alarms related to irritation, degradation of materials, corrosion of electronics and odors.
SAAF™ Reactivity Monitoring CouponsAAF’s SAAF™ Reactivity Monitoring Coupons (RMCs) consist of copper and silver coupons mounted on a plastic panel. RMCs function by reacting with the environment (gases, relative humidity and temperature) to form various corrosive films. This technology is used to investigate the condition of control rooms or other protected environments in industrial facilities such as pulp and paper mills, petrochemical refineries and chemical plants. AAF’s Air Quality Analysis Report clearly documents the findings from the analysis of the coupons, so that the appropriate measures can be taken for further improvement of the air quality.
Please contact your local AAF sales office for more information about the SAAF™ tools.
The SAAF™ media and delivery options can be combined with several possibilities in equipment, offering a total solution for the protection of both particulate and gaseous contaminants. The equipment solutions vary from PORTA-Scrubbers, Deep
Bed Scrubbers (DBS) 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 particulate pre- and final filters from AAF.
