6W High-Efficiency Big Diameter Axial Fan For Engine Cooling
The 6W is a large-diameter adjustable-pitch axial fan blade covering 560-2200 mm with 6 to 12 blades on W-3 or W-6 hubs, in PAG, conductive PAGAS or die-cast aluminium.
The W Series is the large industrial range covering 560-2200 mm with the 1W, 5W, 6W, 9W and 11W models, 6-12 blades and PAG, PAGAS or ALU materials on W-3 to W-10 hubs.
The W Series covers the large end of the range from 560 mm up to 2200 mm. Five production models, 1W, 5W, 6W, 9W and 11W, use six to twelve blades on W family hubs that run from the 2 kg W-3 up to the 8.76 kg W-10.
These fans are specified where a large volume of air has to move at moderate rotational speed: cooling towers, livestock houses, high performance moving-air units and the cooling packages of low-speed generator sets. The adjustable pitch and the range of hubs allow one impeller family to be tuned across duties that would otherwise need different fan types.

| U10W | Adjustable | 6 / 7 / 8 / 10 | 1000-2200 mm | PAG / PAGAS | W-3 | U10W large axial fan |
The U10W impeller in the same large-diameter class, covered by the U Series, runs 6, 7, 8 or 10 blades from 1000 to 2200 mm.
Blade material is selected from the working temperature and from the atmosphere around the impeller:
| Material | Composition | Temperature range | Typical duty |
|---|---|---|---|
| PAG | PA6 with 30% glass fibre | -40 °C to 110 °C | Heavy-load cooling, anti-aging, general engine cooling |
| PAGAS | PA6 with 15% carbon fibre and 15% glass fibre (conductive) | -30 °C to 100 °C | Dust and gas atmospheres where static discharge must be avoided |
| ALU | Die-cast aluminium ADC12 | -40 °C to 150 °C, short-term 300 °C for 2 h | High-temperature and fire-resistance zones |
The conductive PAGAS option is supplied for equipment working in explosive-risk atmospheres such as dust or gas. It addresses the working environment of the blade; machine-level certification remains the responsibility of the equipment builder.
Blades are supplied with matched hub sets. The hub carries the blade loads and sets the shaft interface, so it is selected together with the blade count:
| Hub type | Weight | Hub diameter |
|---|---|---|
| HUB W-3 | 2 kg / set | 200 mm |
| HUB W-7 | 4.76 kg / set | 328 mm |
| HUB W-8 | 6.38 kg / set | 390 mm |
| HUB W-10 | 8.76 kg / set | 480 mm |
This series is normally specified for the following duties:
Cooling towers and large heat exchangers
Livestock ventilation
High performance moving-air units
Off-highway engine cooling and low-speed generator set dissipation
When a fan is being specified or replaced, the following points are confirmed before a blade set is released. They are the same checks used for OEM programs and for retrofit projects.
Duty point: airflow and static pressure required at the working speed, taken from the cooling pack or ventilation requirement
Installation: available diameter, shroud clearance, mounting pattern and the shaft interface of the existing hub
Environment: maximum air temperature, dust or gas atmosphere, and whether static discharge has to be avoided
Drive: available power, belt or direct drive, and whether the fan has to reverse in service
Service: blade weight for handling during maintenance and spare-part availability across the machine fleet
Blade count, profile and material are then matched to those conditions in a fixed order: material first, then blade count, then hub family, with diameter confirmed against the shroud. Working in that sequence keeps the mechanical interface stable when the duty requirement changes later in the project, and it is why the same blade family can often stay in production while the cooling pack is revised.
Large impellers are balanced on a hand laser balancing machine before shipment. Blade pitch is set at assembly and the hub family is recorded, so a replacement blade set can be matched to the original duty point.
Blade count, blade profile, hub family and material can be customized for OEM programs, and existing fans can be reviewed when airflow, noise or durability has to be improved on a running machine. For the largest diameters, the U Series continues the concept from 1000 mm to 2200 mm with the U10W impeller.
