Standard Features Include:
- Straight aerofoil design – the D-Series fan rotates clockwise in the horizontal plane
- 20ºC to 65ºC operation – the D-Series fan works in hot and cool industrial environments
- Polyurethane-coated steel hub – the D-Series fan also has aluminum blade supports and stainless steel U-bolts, nuts and washers
Optional Features Include:
- Up to 120ºC operation – with special modifications, the D-Series fan can operate in temperatures above the 65ºC standard limit
- Upgraded Leading Edge blade protection – we can better protect the blade for use in wet cooling applications
- Upgraded materials and coating – we can upgrade the D-Series fan so that it’s appropriate for sea water cooling tower applications
- Coupling flanges – we can supply cast iron, polyurethane-coated coupling flanges to mate with drive shafts having either a cylindrical bore or a tapered bushing connection
- Blades: FRP (Pultruded Fiberglass)
- Blade Supports: Aluminum
- Hub: Polyurethane Coated Steel
- U-bolts: Stainless Steel
- Fasteners: Stainless Steel
Pro D-Series – 26′ – 36′ | 5 – 8 Blades

Product description
The Howden Pro D-Series 26′-36′ (7.93M-10.98M) cooling tower fans are highly-efficient cooling fans which combine the highest aerodynamic performance with very low power consumption.
- 9 – 11 Blades
- Delivers high efficiency and reduces power consumption
- Boosts cooling performance designed to deliver the optimum aerodynamic performance
- Damps down mechanical vibrations the FRP blades offer superior damping of mechanical vibrations and great chemical resistance
- Durability and longevity the fan blade is integrated (rather than bolted on) to the shaft, reducing mechanical stress at the joints
- Simple to assemble – D-series fans come with clear technical documentation
- Applications – Field-erected cooling towers, air-cooled condensers (ACC)
