Axial Fan Accessories | McMaster-Carr

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—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.

Collars for Wall-Mount Exhaust Fans

Connect your wall-mount exhaust fan to a louver. One side of the collar fits around your exhaust fan and the other includes a flange for mounting a louver. Overall height and width include the mounting flange.

Note: To be compatible with the fan, the collar must be larger than the overall fan dimensions. To be compatible with the louver, the collar's For Louvers That Fit Opening Height and Width must match the louver's For Opening Width and Height.

Fan Shroud Filters


Fan-Front Mount	Fan-Back Mount


Fan-Front Mount Polypropylene Filter	Fan-Back Mount Polyester Plastic Filter	Fan-Back Mount Polypropylene Filter

These filters fit over fans with round guards to trap dust and debris, keeping contaminants out of the air and off of your fan. An elastic band holds them securely in place.

Fan-Front Mount—Fan-front-mount filters fit over the entire front of fans, blocking dust that has entered the fan from blowing back out into the air.

Fan-Back Mount—Fan-back-mount filters have a center hole, and secure around a fan’s motor housing with a hook and loop closure. They filter air as it enters the fan, protecting the blades and bearings from wear and damage while also reducing the amount of dust the fan will blow out.

Polyester Plastic Filter—Polyester plastic filters are disposable—replace them when they’re dirty.

Polypropylene Filter—Polypropylene filters have an electrostatic charge that attracts particles, and can be washed and reused.

White—Dirt and dust stands out on white filters, so it’s easy to see when they need to be cleaned or replaced.
