Fan Blades
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.
