X7 Fan
OVERVIEW The Marley X7 fan is designed for induced-draft cooling tower applications, offering distinct advantages over other fan designs.


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.


Genuine Marley OEM parts are precision-engineered to provide you with a reliable product. While other suppliers may offer parts at an initial savings, you risk lowering performance — and losing FM and CTI ratings. Marley OEM parts provide the durability you can trust because we design and manufacture them exclusively for cooling towers.

With plant operation relying on your cooling tower performance, it’s important to select the parts that are among the highest quality available — Marley OEM parts.
