Nylon Fan 18in 6 Blade

The Nylon Fan 18in 6 Blade is a mechanical cooling fan engineered for demanding engine applications where reliable thermal management is non-negotiable. Designed with a universal bolt pattern and compact footprint, this fan delivers consistent airflow without the electrical complexity of modern clutch fans—making it ideal for high-performance builds, emergency vehicle fleets, and field-deployed equipment that requires simplicity and durability. The 18-inch diameter and six-blade configuration strike the critical balance between cooling capacity and parasitic load, ensuring your powerplant stays within optimal operating temperature under sustained operational stress.

Constructed entirely from nylon, this fan blade assembly eliminates corrosion and reduces weight compared to steel alternatives—a significant advantage in mobile platforms or weight-sensitive installations. The 5/8-inch pilot ensures centered mounting on most standard engine hubs, while the universal bolt pattern accommodates a wide range of radiator shroud configurations. Nylon construction also provides inherent vibration damping, reducing noise transmission to the cabin and minimizing stress on mounting hardware during extended high-speed operations. The fan's six-blade geometry optimizes blade chord and pitch to move maximum CFM with minimal rpm penalty, keeping engine temperatures stable without sacrificing fuel efficiency or drivetrain responsiveness.

This cooling fan is best suited for operators running carbureted engines, mechanical water pumps, and traditional cooling systems where direct-drive fans are standard practice. Field personnel managing fleet vehicles, off-road tactical platforms, and specialty equipment benefit from the simplicity of mechanical cooling—no electronic sensors to fail, no clutch wear to monitor. Installation requires only basic hand tools and alignment to the existing hub and shroud mounting points. The lightweight nylon construction (0.78 lbs) makes for straightforward installation in confined engine bays, and the universal bolt pattern ensures compatibility across multiple engine platforms without custom fabrication.
