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
A
B
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).

Collars for Wall-Mount Exhaust Fans
Collar
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 Air Filters
For Fan Front
For Fan Back
Polypropylene for Fan Front
Polyester for Fan Back
Polypropylene for Fan Back
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.
Front-mount filters fit over the entire front of fans, blocking dust that has entered the fan from blowing back out into the air. 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 filters are disposable—replace them when they’re dirty. Polypropylene filters have an electrostatic charge that attracts particles, and can be washed and reused.
Dirt and dust stands out on white filters, so it’s easy to see when they need to be cleaned or replaced.
