The SPAL EF3524 (VA10-AP50/C-25S) is a premium, high-performance 12V 12-inch electric pusher fan engineered for demanding automotive cooling applications. Designed for maximum reliability, this medium-profile straight-blade fan delivers an impressive 1070 CFM of airflow, making it the perfect upgrade for radiators, oil coolers, and intercoolers where engine bay space is limited. Common Applications & What People Use It For As a high-output universal fan, the SPAL EF3524 is widely trusted by mechanics, fabricators, and motorsport teams across New Zealand for the following uses: - Front-Mount Radiator Cooling: Installed directly on the grille side of the radiator to push air through the core. This is essential when a large engine swap leaves no room for a puller fan on the engine side.
- Intercooler & Turbo Setups: Used to maintain stable intake temperatures on front-mount or top-mount intercoolers in turbocharged and supercharged vehicles.
- Transmission & Oil Coolers: Mounted to auxiliary fluid coolers on heavy-duty 4WDs, tow vehicles, and track cars to prevent transmission overheating under heavy loads.
- Air Conditioning Condensers: Added as secondary auxiliary cooling to boost A/C efficiency at idle or during low-speed driving in classic cars and modified street builds.
- Motorsport & Off-Road Projects: Popular in drift cars, circuit racers, and jet boats due to its IP68 waterproof rating, allowing it to survive extreme vibration, mud, and water exposure.
