DeWitts® 32-SP480 Universal Shroud and Brushless Cooling Fan

It is not always an easy, cut-and-dry, mounting solution to add an automotive electric fan to your street rod or muscle car. Often engine swaps, accessory drive conversions, and extra thick radiators all add up to not much room for automotive cooling fans. Fitting an electric fan that will cool your engine properly is made much easier with the use of a DC brushless fan that is designed to work in conjunction with a shroud that provides full coverage of your radiator's core.

An industry exclusive solution for mounting SPAL's 300 or 500-watt brushless fans to nearly any radiator. Injection molded from a heat resistant space age polymer offering decades of performance and durability. Easily trimmable to fit most applications and offers full coverage on core sizes between 22.5" to 27.5" wide. A "Direct Fit®" on all models built with hat channel side supports. Includes all mounting hardware and flaps.

The new SPAL brushless fans are ideal for engine and oil cooling, HVAC, and auxiliary cooling applications. These new fans were developed and designed with cutting edge technology, high energy ferrite magnets, and a state-of-the-art sine wave sensorless drive. These motors reach more than 82% electrical efficiency, placing our 300W and 500W power range products among the most efficient motors available anywhere. The result is high air-side performance at minimum electrical load. SBL motors are fully sealed to be IP68 and IP6K9K compliant and can operate in the presence of many aggressive or hazardous substances.
