9in Curved Blade Low Profile Fan Pull

The SPAL Advanced Technologies 9-inch curved blade low profile fan pull (part number 30100452) is a puller-style electric cooling fan engineered for compact engine compartments and tight mounting spaces. Operating at 625 CFM (cubic feet per minute) on a 12-volt electrical system, this low-profile electric fan delivers efficient airflow while maintaining a minimal footprint—critical for applications where traditional thick radiator fans create clearance conflicts with headers, intake manifolds, or custom engine bay fabrication.

Specifications confirm this fan's optimization for space-constrained installations. The 9.688-inch square mounting footprint pairs with a 2-inch thickness profile, allowing integration into engine bays where stack-height is severely limited. The curved blade design improves air acceleration and pressure distribution compared to flat blade designs, translating to better cooling efficiency per watt of draw. The plastic construction reduces weight and eliminates corrosion concerns common in aluminum housings exposed to moisture and road salt. At 625 CFM, this unit provides adequate cooling for modest displacement engines, street-driven vehicles, or auxiliary cooling roles where maximum cfm is less critical than installation flexibility.

This fan serves builders, hot rod shops, and engine swap specialists who prioritize installation simplicity and fitment in tight quarters. Street rod applications, engine conversions into classic car frames, and custom cooling system builds benefit from the low-profile geometry. The puller configuration—drawing air through the radiator rather than pushing—is the standard choice for aftermarket or remote-mount radiator setups where fan-to-core spacing is engineered separately. Wiring to a thermostat switch or controller is straightforward with 12V DC operation.
