High Performance Flex Fans feature a narrow blade for good airflow in tight space applications. Embossed centre hubs and four-rivet blade attachment provide increased strength. These are stainless steel blades, rated up to 7000 RPM, with standard rotation. They have a black powder coated hub.

Designed for use with flex fans, spacers allow adjustment of fan-to-radiator clearance. Each kit includes spacer, washers and bolts.
