The 2-blade and 3-blade weedless propellers are commonly used on aeration and mixing equipment employed in water and wastewater treatment applications. The weedless propeller was designed by Michigan Wheel to be utilized in applications where solids and other stringy material may be encountered. The non-fouling design eliminates material build-up on the propeller, mitigating equipment failure. The weedless propeller is available in a "full" blade tip design for open liquid applications, or a "clipped" blade design for improved efficiency in a duct. This style of propeller is investment and sand cast depending on size.

If we do not have a pattern or die to meet your needs, we can utilize our CAD/CAM and CNC pattern and propeller making capabilities to fulfill your needs.

Options:
1. Standard setscrew(s) or keyway provided with propellers.
2. Special bores such as splined and threaded are available upon request.
3. Clipping of propeller blades available upon request.

Clipped Weedless “CW”
The clipped propeller is made by clipping (a modified cutting procedure) a larger diameter unclipped “FW” propeller such that it will fit inside a tube or duct. Typically, an unclipped propeller with a diameter of up to two or more inches larger than the tube/duct i.d. is used to make the clipped propeller.
