    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 B and C—Styles A-C blades are for use in low-airflow applications.
    Style D—Style D blades are sturdier than Styles A-C blades and produce higher airflow.
    Style E—Style E blades are cupped to create a focused stream of high airflow.
