What we do
Five market-facing divisions, one accountable group.
Waste Water Treatment
Serves water and wastewater treatment customers: municipal corporations, industrial ETP operators, EPC contractors, real estate and institutional developers, and the consulting and DPR firms that specify equipment for government and PSU infrastructure tenders. Portfolio includes aeration systems, MBBR and tube settler media, clarifiers, sludge dewatering machines, dissolved air floatation systems, packaged STP/ETP plants, and full turnkey treatment plant builds.
Why AIRFIN
Reliability is built at the casting bench, on the assembly line, and on the test rig — not bought and re-stamped.
In-house manufacturing
We make what we sell — casting, machining, fabrication, molding, assembly, and test under one roof.
Application-specific range
The pump portfolio alone covers ten duty classes, so you get the right product, not a near-fit.
Honest selection
When we don't have the right product for an application, we say so. It's the basis of repeat business.
Manufactured in the USA & India
ANSI- and ISO-standard equipment built to international spec, without the lead time and service risk of imports.

From municipal utilities to chemical, pharma, textiles, food, power, and infrastructure.
- Municipal

Our manufacturing brands
Each brand makes its own products for its own customers — backed by the group's shared manufacturing and quality.
Built at the bench, not bought and rebadged
AIRFIN was founded in 1990 on a deliberate stance: make the equipment we sell. Three decades on, that's still the operating principle of the company.
