Fan Blades

Keyway

Replace worn and damaged fan blades. Use the included set screw or shaft collar to fasten a blade to your fan's shaft. Fan blades with a keyway are for use on motors with a keyed shaft. For difficult-to-remove hubs and fan blades, use fan blade pullers (not included).

Styles A-C blades are for use in low-airflow applications.

Style D blades are sturdier than Styles A-C blades and produce higher airflow.

Style E blades are cupped to create a focused stream of high airflow.

High-Output Fan Blades

Keyway

Generate at least 25% greater airflow than standard fan blades. Use these blades to replace worn and damaged fan blades. The fan blades with a keyway are for use on motors with a keyed shaft. For difficult-to-remove hubs and fan blades, use fan blade pullers (not included).

Style A blades include a shaft collar to fasten a blade to your fan's shaft.

Style B 12"-24" dia. blades use the included set screw to fasten a blade to your fan's shaft. The 30" and 36" dia. blades require an SH style quick-disconnect bushing (not included).
