Axial Flow Fan for Cooling Tower — Manufacturer & Supplier
Vayuvents Pvt. Ltd. manufactures and supplies FRP axial flow fans for cooling tower applications — from small HVAC cooling towers to large industrial process cooling towers in power plants and refineries across India and export markets.
Cooling towers reject heat from industrial processes and HVAC systems by evaporating a small portion of circulating water into the airstream. The axial fan is the heart of the cooling tower — it drives the large volume of air through the tower fill media required for effective evaporative cooling.
Cooling tower environments are exceptionally demanding — continuous exposure to warm, humid, salt-laden air creates rapid corrosion of standard MS components. Vayuvents supplies FRP blades and GI or FRP casing for cooling tower axial fans, providing the corrosion resistance needed for long maintenance-free service life.
We supply both induced-draft fans mounted on top of the tower and forced-draft fans mounted at the base. Fan speed and pitch are selected to achieve the required airflow for the tower thermal duty at lowest possible energy consumption.
How It Works in This Application
Air Intake
The axial fan draws ambient air into the cooling tower through louvers at the tower base or forces air in from the base depending on the draft configuration.
Air Flow Through Fill Media
The airstream passes upward through the fill media where it contacts warm process water flowing downward, achieving evaporative heat transfer.
Evaporation and Heat Rejection
A small percentage of water evaporates, carrying latent heat away in the exhaust airstream and cooling the remaining water by 5 to 12 degrees Celsius.
Exhaust to Atmosphere
The warm humid air exits at the top of the tower. The cooled water collects in the basin and is pumped back to process heat exchangers.
Recommended Variants
FRP Blade Axial Fan
Fibreglass-reinforced plastic blades for maximum corrosion resistance in the warm, humid, chemical-laden cooling tower airstream.
Most RecommendedAdjustable Pitch Axial Fan
Variable pitch blades allow airflow adjustment to match seasonal changes in cooling demand without changing fan speed.
Aluminium Blade Axial Fan
Lightweight aluminium blades for smaller cooling towers with clean process water in less corrosive environments.
Gear-Drive Axial Fan
Motor drives fan through right-angle gearbox — motor runs outside the humid airstream, extending motor life in very large towers.

FAQs
FRP (fibreglass-reinforced plastic) blades are the best choice for cooling tower applications. They are inherently corrosion-resistant to the warm, humid, chemically-treated water environment inside a cooling tower and last significantly longer than aluminium or MS blades.
Induced-draft fans are mounted at the top of the tower and draw air upward through the fill. They are more common and energy-efficient. Forced-draft fans are at the base and push air upward. Vayuvents supplies both configurations.
Yes. Vayuvents manufactures replacement cooling tower fans to match the dimensions of existing towers. Send us the existing fan diameter, pitch angle, RPM, and motor power — we will supply a matched or improved replacement.
Installing adjustable pitch blades allows airflow to be reduced during cooler ambient temperatures. VFD on the fan motor is another effective method, reducing power by up to 50% at 80% speed.
Cooling tower axial fans typically run at 200 to 600 RPM for large diameter fans (1,500mm to 9,000mm). The low RPM reduces noise and extends blade and bearing life.
Yes. Vayuvents exports cooling tower axial fans to Saudi Arabia, UAE, Qatar, and Oman with motors rated for 50 to 55 degrees Celsius ambient temperature and full export documentation.
