SPAL Fans by Size

Small-diameter fans (4in, 5.2in, 6.5in and 7.5in) are commonly used for oil coolers, differential coolers and auxiliary cooling duties. Mid-size fans from 9in to 12in suit smaller radiators and twin-fan setups, while 13in, 14in and 16in fans are typically used on larger single-fan radiator applications. The range also includes low profile and medium profile curved and straight blade fans, high performance and High Output (H.O.) models, dual fan assemblies, and 300W, 500W and 850W brushless fans supplied with a jumper harness. Related mounting brackets, harnesses and temperature control sensors are listed separately.

Fan diameter is the primary fitment identifier in this collection, so measure the available core area on your radiator or cooler before ordering, including space for the mounting brackets or shroud. Also check the depth available between the core and the engine, pulleys or bonnet line, as low profile and medium profile fans have different overall thicknesses to high performance models. Decide whether you need a pull fan (mounted on the engine side, drawing air through the core) or a push fan (mounted on the front, blowing air through), and confirm your charging system can support the current draw, particularly for high performance, High Output and 500W or 850W brushless fans. Brushless models require the matching jumper harness and, where variable control is desired, a compatible temperature control sensor.

Typical installation involves securing the fan with bracket kits, strap brackets or mounting pins, then wiring it through a relay, fuse and appropriate switching or temperature control. Brushless fans use a dedicated jumper harness and may require a harness adapter. Installation by a professional is recommended, and wiring should be carried out to the fan manufacturer's instructions and to Australian electrical practice.

What does push or pull mean? A pull fan mounts behind the core and draws air through it; a push fan mounts in front and blows air through. Pull configurations are generally preferred where space allows.

How do I choose a fan size? Measure the usable core area and available depth, then select the largest diameter that fits with room for mounting hardware.

Do brushless fans need extra parts? They are supplied with a jumper harness; variable speed control also requires a compatible temperature control sensor, sold separately.
