The SPAL EF3570 (VA31-A101-46A) is a premium, ultra-compact 12V 5.2-inch electric puller fan engineered for specialized automotive, motorcycle, and motorsport cooling solutions. This high-efficiency paddle-blade fan features an open shroud design that delivers a strong 342 CFM of airflow to pull heat directly away from your cooling core. Important Note: This specialized fan body does not feature built-in feet slots and cannot be used with standard SPAL clip-on mounting feet. It is designed for flush custom mounting or universal pin/bracket configurations. Common Applications & What People Use It For Due to its compact 5.2-inch diameter and high-output motor, the SPAL EF3570 is widely trusted across New Zealand for the following applications: - Racing Motorcycles & ATVs: A highly popular cooling upgrade or factory replacement for dirt bikes, enduro bikes, quad bikes, and road cruisers that run hot during low-speed trail riding or at idle.
- Auxiliary Transmission & Oil Coolers: Perfectly sized to mount directly onto aftermarket engine oil coolers, power steering coolers, or remote automatic transmission fluid (ATF) coolers on performance track cars and heavy tow vehicles.
- Karts & Micro Sprints: Extensively used in shifter karts, custom off-road buggies, and micro-light vehicles with extremely confined radiator real estate.
- Agriculture & Machinery Cabin Ventilation: Frequently utilized to provide heavy-duty electrical enclosure ventilation or compact cab air circulation in farming and industrial equipment.
- Harsh Environment Projects: Engineered with a fully sealed, IP68 waterproof motor casing to ensure reliable operation in mud, dust, and wet off-road environments.
