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.

Indoor air quality moved from a compliance line to a specification requirement after 2020, and filtration and ventilation demand has held rather than reverted. The equipment is unglamorous and the manufacturers are small, but the aftermarket (filters, service, commissioning) recurs against an installed base that only grows.
