AAF SAAF™: Advanced Gas Phase Filters for Molecular Contamination Control
In modern indoor environments, controlling particulate matter is no longer enough. Gaseous contaminants such as VOCs (volatile organic compounds), acidic gases, and industrial emissions pose serious risks to people, processes, and sensitive equipment. To tackle these invisible threats, AAF International developed the SAAF™ (Strategic Airfiltration & Adsorption Framework) line of gas phase filters—a cutting-edge solution designed for chemical and odor removal in critical applications.
Whether you're managing a data center, hospital, museum, or refinery, AAF SAAF™ filters deliver targeted molecular filtration to ensure clean, safe, and compliant indoor air.
What is AAF SAAF™?
AAF SAAF™ is a complete line of gas phase filtration media, filters, and systems designed to remove gaseous contaminants through adsorption, chemisorption, or a combination of both. The acronym "SAAF" stands for Strategic Airfiltration and Adsorption Framework, representing AAF's commitment to molecular-level air purification.
SAAF™ solutions are used as standalone systems or integrated into HVAC units to eliminate corrosive, odorous, or toxic gases such as:
-
Sulfur dioxide (SO₂)
-
Nitrogen dioxide (NO₂)
-
Ozone (O₃)
-
Ammonia (NH₃)
-
Formaldehyde
-
VOCs (e.g., benzene, toluene, xylene)
-
Hydrogen sulfide (H₂S)
-
Chlorine and acid gases
Key Features of AAF SAAF™ Gas Phase Filters
-
✅ Wide Range of Media: Activated carbon, activated alumina, impregnated media for broad-spectrum or targeted contaminant removal.
-
✅ Customizable Configurations: Panels, cassettes, cylindrical cartridges, or loose-fill media for refillable housings.
-
✅ High Adsorption Capacity: Engineered for extended service life and minimal pressure drop.
-
✅ Modular Systems: Easily integrated into AHUs, pressurization units, cleanroom modules, and standalone scrubbers.
-
✅ Real-Time Monitoring Support: Compatible with AAF’s SAAFShield® sensing technology for corrosion and IAQ data.
How Does AAF SAAF™ Work?
SAAF™ systems use a combination of physical adsorption and chemical reaction to neutralize gases:
-
Adsorption: Gases adhere to the surface of activated carbon or alumina via Van der Waals forces.
-
Chemisorption: Impregnated media chemically react with specific gases to neutralize them permanently.
-
Oxidation: Some media types promote oxidation of reactive gases, converting them into harmless compounds.
SAAF™ Media Types Include:
| Media Name | Target Contaminants |
|---|---|
| SAAFBlend™ GP | Acid gases (SO₂, NO₂), VOCs |
| SAAFBlend™ IAQ | Indoor air pollutants, aldehydes, organic acids |
| SAAFOxidant™ | Ozone, reactive oxidizing gases |
| SAAFAmmonia™ | Ammonia and amine-based compounds |
| SAAFCarb™ | VOCs, odors, hydrocarbon vapors |
| SAAFCassette™ | Modular media containment for AHUs and FFUs |
Each media is laboratory-tested and field-validated for capacity, efficiency, and pressure drop.
Benefits of AAF SAAF™ Gas Phase Filtration
1. Protects People and Equipment
In environments like data centers, telecom rooms, and semiconductor fabs, gaseous corrosion can degrade sensitive electronics. SAAF™ filters help protect these assets from failure and reduce downtime.
2. Improves Indoor Air Quality (IAQ)
SAAF™ removes VOCs and harmful gases that cause headaches, respiratory issues, or long-term health risks. Ideal for use in hospitals, airports, schools, and office buildings.
3. Odor Control
Effectively eliminates odors from wastewater treatment plants, kitchens, chemical storage, and industrial exhausts, providing cleaner, more comfortable environments for occupants and workers.
4. Regulatory Compliance
Helps industries comply with OSHA, ASHRAE, WHO, and local IAQ regulations, especially in hazardous areas or cleanroom environments.
5. Flexible, Scalable Solutions
From retrofit filter banks to standalone air scrubbers, SAAF™ can scale to meet the air purification needs of small rooms or large industrial campuses.
