Axial Fans for Industrial Applications
Axial fans are typically used in handling critical processes that require drying, ventilation, fume & hot air exhaust and consist of a propeller rotating in a round section of duct. An Axial fan consists of blades that rotate around a fixed axis. The blades of an Axial fan draw in the air in a linear direction parallel to the shaft and force it out of the opposite side, still in a linear direction.
Compared to a Centrifugal fan, an Axial fan has higher sound output but is more compact and better for high volume flow rates at lower pressure.
Axial fans are available in a variety of set-ups depending on each individual application. These include:
- Direct drive – where the impeller is mounted directly on the driveshaft
- Belt drive – where the driver is mounted on the outside of the fan casing
- Bifurcated – where the motor is enclosed in a tunnel inside the fan housing
- Roof mounted – fitted with a rain cowl and weather flaps
- Plate mounted – for simplified installation
- Flue fans – for operating temperatures up to 500°C
- Auxiliary mine ventilation fans with pressures to 12,000Pa
