PWM Single RAD Fan/ Aluminum Shroud Assembly

The DERALE PWM Single RAD Fan with Aluminum Shroud Assembly is a high-performance electric cooling solution engineered for demanding engine management applications. This 17-inch puller-style fan combines PWM (Pulse Width Modulation) control technology with a robust aluminum shroud to deliver efficient thermal regulation in compact installations. The 2400 CFM airflow rating ensures reliable cooling capacity across a wide operating envelope, making this assembly suitable for both street and performance-oriented vehicles requiring adaptive cooling management.

Specifications highlight the engineering priorities built into this assembly. The curved blade design maximizes air movement while reducing noise signature compared to flat-blade alternatives. Operating at 12V, the fan integrates with standard automotive electrical systems and vehicle management computers via PWM interface, allowing dynamic speed modulation based on real-time coolant temperature and engine load. The overall footprint measures 20.75 x 17.625 inches with a 3-inch thickness, optimizing fit within constrained engine bay layouts. Weighing 14.3 pounds, the assembly balances structural durability with minimal parasitic mass penalty.

The aluminum shroud construction provides corrosion resistance critical in high-moisture or salt-air environments, while the plastic components are selected for thermal stability under sustained cooling loads. This configuration is deployed in retrofit cooling upgrades where OEM fans prove insufficient, aftermarket engine builds requiring upgraded thermal capacity, and marine applications where salt corrosion demands material durability. The PWM Single RAD Fan Assembly represents DERALE's commitment to precision thermal management, addressing buyers who require intelligent, space-efficient cooling without compromise on airflow capacity or reliability.
