Products and engineering, delivered as working systems
AIRFIN combines its manufactured equipment with field engineering to deliver packaged plants, turnkey builds, pumping stations, and lifecycle services — under one line of accountability.
Engineering & field services
Lifecycle services delivered directly by AIRFIN teams.
Waste Water Treatment
Erection, Commissioning & Startup
Site installation, commissioning, and startup of treatment equipment and systems.
Plant Audits & Efficiency Studies
Structured audits of treatment plant performance: energy consumption, oxygen transfer efficiency, and process bottlenecks.
Plant Upgrades & Retrofits
Performance uplift of existing treatment plants: aeration replacement, MBBR conversion, and clarifier upgrades without full rebuilds.
Pumping
Application Engineering & Pump Selection
Duty-point analysis and honest pump selection across ten duty classes and a wide material range.
Pump Repair & Overhaul
Repair, overhaul, and re-rating of pumps, including competitor-brand units.
Reverse Engineering & Legacy Spares
Remanufacture of spares for legacy and obsolete pumps using in-house pattern-making, casting, and machining.
Witness & Performance Testing
Customer-witnessed hydraulic performance testing at the in-house test facility, with material and performance certificates.
Engineering & R&D
Custom Equipment Fabrication
Bespoke fabricated equipment for applications no standard product serves.
Process Engineering, Applied Research & Specialty Consultation
Scoped engagements applying the group's process and product engineering depth to a defined problem.
How a project runs
From first conversation to a plant that performs.
- 01
Consultation
We characterise the application — effluent, duty point, site constraints — and tell you honestly whether we're the right fit.
- 02
Design
Process and mechanical design anchored in real characterisation, drawing on the in-house product range and custom fabrication where needed.
- 03
Manufacturing
Equipment is cast, machined, fabricated, and tested in-house — not procured — so the system arrives matched, not assembled.
- 04
Implementation
Site erection, commissioning, and startup by teams who know the equipment because the group built it.
- 05
Support
Spares, service, audits, and upgrades across the lifecycle, from one accountable manufacturer.

Bring us the application. We'll design the system — or tell you honestly if we're not the fit.
