17in Hd Stainless Flex Fan

The DERALE 17-inch HD Stainless Flex Fan (Part No. 17617) is a mechanical cooling fan engineered for high-demand engine cooling applications where reliable, efficient heat rejection is critical. Built with a 6-blade design and stainless steel construction, this universal-fit flex fan delivers superior cooling performance across a wide range of engine configurations and operating conditions.

The fan's 17-inch diameter and stainless steel blade material provide exceptional durability and corrosion resistance, essential for extended use in marine, off-road, and harsh-environment applications. The 5/8-inch pilot hub accommodates standard water pump mounting, while the steel hub with black powder-coat finish ensures secure installation and long-term reliability. The flex fan design allows blades to pitch and flatten under high rpm loads, reducing parasitic horsepower loss and improving overall engine efficiency. This mechanical approach requires no electric controls or batteries, making it ideal for vehicles where electrical simplicity and proven dependability are priorities.

This fan is optimized for automotive enthusiasts, off-road builders, and engine specialists who demand robust cooling without electrical complexity. Whether upgrading an older engine bay, building a custom vehicle, or replacing a failed cooling component, the DERALE 17-inch HD Stainless Flex Fan provides proven, no-frills thermal management. The stainless construction resists rust and corrosion in saltwater environments, making it equally valuable for marine and coastal vehicle builds.

Mechanical flex fans remain the standard for high-horsepower naturally aspirated engines and applications where engine bay temperature control must occur independently of electrical systems. DERALE's engineering focuses on durability and thermal performance, making this 17-inch model a trusted choice for serious cooling upgrades.
