SPAL fans can be mounted in various ways, the fans have bolt holes and slide-in mounting flanges around the circumference of the housing. The most popular method is by using the Bracket & Strap mount, the straps are made from powder-coated steel and are approximately 200mm long, for most applications they are long enough to reach mounting flanges on the top, bottom or sides of the radiator. Other mounting brackets are available in lengths of 20, 30 and 60mm.
We also offer a few sizes of through-core mounting bolt kits; however these aren't recommended for heavy fans as they will eventually damage the radiator.
Our mounting kits are sold separately.
Q & A
Q: Should I buy a SPAL fan?
A: SPAL have been around since 1959 and are the go-to manufacturer for OEM's and the aftermarket for ultra-reliable and high performance fans and blowers, their products are built to last. When a manufacturer offers a 36-Month warranty on their products then you know it's good quality. Buy it once, buy SPAL.
Q: What fan size should I choose?
A: Go for the biggest fan you can fit, if you have a slim and long radiator then it may be best to run twin fans, especially in warmer climates.
Q: Standard, Standard Plus, High Performance & Brushless Motors?
A: Most SPAL fans are available with Standard, Standard Plus and High Performance motors that operate at a higher RPM and flow proportionately greater amounts of air, a higher electrical consumption and greater noise level are the trade-offs. Even though the blade and housing depth doesn't change for the more powerful motors, they are thicker and more room is required to install the fan.
Brushless Motored fans offer variable fan speed via PWM signal, they offer the highest waterproof rating (IP6K9K) and the longest service life of 30,000 hrs MTBF. Usually only very specialist applications warrant these features.
Q: Which motor type should I choose?
A: The standard fans are fine for most applications, this is the type that we run on most of our projects here at the shop. For cars that are running extra thick radiators with air conditioning, turbo intercoolers or transmission coolers it is recommended to move up to a more powerful motor over the standard type. Remember that rad fans also help keep engine bay temps in check.
Q: How do I control the fan?
A: We recommend wiring them up to be activated using a temperature sender in your vehicle's cooling system. A toggle switch is not recommended as you may forget to turn it on at the proper time - plus this is one less thing to worry about!
Q: Can the fans run in reverse?
A: Technically yes, you will not damage the motor running the fan in reverse, however the blades are optimised to run in one direction only and you will be sacrificing efficiency and airflow by not running the fan the correct rotation. The brushless fans cannot be run in reverse, you will damage the motor by reversing the polarity.
Q: Push or Pull?
A: Push fans sit in front of the radiator and push air through the core, Pull fans sit behind the radiator (usually the engine side) and draw air through the core.
