The Marley FlareTip™ blade enhancement provides increased performance overcoming tip clearance losses—aiding the movement of air next to the fan cylinder.
The wide chord blade design is well suited for low noise operation as well, delivering superior air flow and pressure capability at reduced speed. The high performance X7 airfoil is one of the most efficient in the industry today.
The hollow 6063-T6 aluminum alloy extruded blade is designed with a deep section airfoil making the X7 robust, yet light and easy to handle. It also withstands the extreme heat and humidity imposed by the rigorous cooling tower environment.
