Overview

Ventilation & Air Quality Equipment covers fans, blowers, air-handling, filtration, and air-purification equipment for commercial, industrial, and institutional buildings. At ~$8B it is led by ventilation and air-quality specialists (Greenheck, Daikin/AAF, Camfil, Systemair) serving the building and industrial markets.

Demand has been meaningfully boosted by post-pandemic indoor-air-quality awareness (ventilation, filtration, and air purification in schools, offices, and healthcare), alongside energy-recovery ventilation and industrial air-handling needs. It is consolidating, with IAQ a durable structural tailwind.
