17in Hd Stainless Flex Fan

The DERALE 17-inch HD Stainless Flex Fan (Part No. 17617) is designed for automotive enthusiasts and mechanics seeking effective cooling solutions for various engine applications. This mechanical fan provides superior heat dissipation without the parasitic load associated with electric fan clutches, making it suitable for street engines, towing, and modified builds.

Constructed from heavy-duty stainless steel, the 17-inch diameter blade assembly offers maximum cooling surface area while resisting rust and thermal fatigue. The flex blade technology utilizes centrifugal force to adjust the pitch of the blades, optimizing airflow efficiency based on engine speed. This design minimizes the risk of mechanical failure associated with traditional fan clutches.

Ideal for hot-climate daily drivers and heavy-duty work vehicles, this fan ensures reliable performance under high-temperature conditions. Its lightweight construction of 4.29 lbs reduces rotational inertia, contributing to overall engine efficiency. The rigid hub and balanced blade profile promote quiet operation and vibration-free performance during aggressive driving.
