Cobra Hi Efficiency Blades

Lau's Cobra Blades are the leading edge propellers! Their swept wing, large blades are less likely to interact with turbulence, thereby reducing the noise that you'd get from a traditional condenser type propeller. The Cobra Blades can be used to replace a square condenser propeller to make the condensing unit up to 10 times quieter! Cobra Blades are made of high strength aluminum. Before purchasing be sure to look at the diameter and the degree pitch that you need for your specific balde.
