RAD Fan with Aluminum Shroud Assembly

The DERALE RAD Fan with Aluminum Shroud Assembly (Model 16818) is a high-output electric cooling fan designed for vehicles requiring efficient engine temperature management in demanding conditions. This 17-inch diameter puller-style radiator fan delivers 2400 CFM at 12V, making it suitable for performance engines, modified vehicles, and applications where factory cooling capacity falls short. The curved blade design maximizes air movement while the durable aluminum shroud assembly protects the fan motor and directs airflow precisely through the radiator core.

Built as a complete kit, this radiator fan assembly includes everything needed for installation. The 18-inch outer shroud diameter fits within standard radiator mounting locations, while the 3-inch thickness accounts for engine bay clearance planning. At 2400 CFM output, the fan moves sufficient volume to prevent coolant temperature creep during stop-and-go traffic, sustained load conditions, or high ambient temperatures—situations where electric cooling fans prove essential. The 12V electrical system integration makes this compatible with most street vehicles and light-duty applications.

This cooling fan kit serves hot rodders, engine rebuilders, and off-road enthusiasts who need reliable auxiliary cooling without the weight and parasitic drag of belt-driven mechanical fans. It's equally valuable in swap scenarios where the original cooling system proves undersized for a larger or modified engine. The aluminum shroud construction balances durability with corrosion resistance, an important consideration for vehicles exposed to salt air or high-moisture environments. Weighing 12.3 lbs, the assembly adds minimal mass while delivering the thermal capacity required for sustained performance driving or towing applications.
