AAF International

What AAF International does

AAF International (legal entity: American Air Filter Company, Inc.) is a Louisville, Kentucky-based designer, manufacturer, and servicer of air filtration systems founded in 1921 and operating as a wholly owned subsidiary of Daikin Industries Ltd. The company is organized into two primary divisions: a Commercial, Industrial & Residential division (High-Purity HEPA, Gas-phase, and HVAC filtration equipment plus services) and an Energy & Industrial Air Quality division (energy filtration equipment and replacement parts, plus industrial dust collection systems including dry, wet, and oil mist collectors). AAF supplies mission-critical environments including nuclear, microelectronics, cleanrooms, and pharmaceuticals, and maintains a five-decade sole-source filtration relationship with NASA (Apollo 11, ISS, Artemis II).

Revenue is generated primarily through hardware sales of filtration equipment and systems, supplemented by recurring aftermarket revenue from replacement filters and parts tied to the installed base, professional services such as the data-driven AAF Optimize gas-turbine optimization and Total Cost of Ownership solutions, and OEM/white-label filtration solutions delivered through a dedicated partner portal. Pricing is quote-based and routed through regional sales contacts, with no public price list published. The go-to-market is region-segmented across six dedicated regional websites (Americas, Europe, IMEA, Asia & Oceania, China & Taiwan, Japan), combining enterprise field sales for industrial and energy customers with direct website access and channel/OEM partnerships for residential, SMB, and industrial OEM customers.
