13in Stainless Steel Fan

The DERALE 13-inch Stainless Steel Fan (Part No. 19313) is a mechanical cooling solution engineered for vehicles requiring flexible, reverse-rotation fan performance. Built with a stainless steel blade construction and steel hub, this 13-inch fan delivers reliable thermal management across light-duty and mid-range cooling applications. The universal bolt pattern ensures broad mounting compatibility, making it a practical upgrade for operators and enthusiasts maintaining vehicles in demanding field conditions.

The six-blade design balances airflow efficiency with structural durability, while the stainless steel construction resists corrosion—a critical advantage in high-salt or humidity-heavy environments. The flex-type mechanism allows the fan to engage and disengage based on engine temperature, reducing parasitic drag and improving fuel efficiency during normal operation. Reverse-rotation capability accommodates non-standard engine configurations, expanding application scope beyond conventional setups. At 3.03 lbs, the unit remains lightweight without sacrificing rigidity, and the 17 x 20-inch footprint integrates into most mid-sized engine bays.

This fan addresses the needs of vehicle owners facing marginal cooling performance or aging fan assemblies. Whether supporting patrol vehicle maintenance, off-road recovery rigs, maritime equipment in corrosive environments, or personal off-grid power systems, the mechanical flex design eliminates belt-driven reliability concerns and delivers measurable thermal output. The stainless blade composition outperforms standard steel in long-term durability, particularly where salt spray or continuous moisture exposure is a factor.

DERALE's mechanical fan engineering prioritizes longevity and straightforward installation. The universal bolt pattern eliminates guesswork during fitment, and the reverse-rotation option ensures this unit works across a wider range of engine and driveline orientations than single-direction competitors. For users seeking a no-electronics, corrosion-resistant cooling upgrade with proven flex-type engagement, the 13-inch DERALE fan represents a field-tested solution backed by decades of automotive thermal management expertise.
