Extended Chord (EC)

The Class 10000 Extended Chord (EC) uses a wider chord to achieve the same air movement with fewer fan blades than our SC model, and it can provide even greater performance when using the same number of blades. An airfoil blade design further increases efficiency while achieving a considerable reduction in noise levels. The trailing edge of the EC blade is robotically spot welded rather than riveted, which lowers surface turbulence and noise while providing the strength needed to endure engine driven applications. The EC fan is available in left-hand or right-hand rotation.

The diameter of the Class 10000 EC ranges from 5 to 18 feet. Adjustable angle blades are available in our standard aluminum or FRP blades and are always equipped with our vortex extended tips to reduce noise levels.

Optional Equipment

We custom manufacture all of our fans to suit your specific application. Our optional equipment and services help ensure our fans fit your exact requirements.

AirBrake^®
Our anti-windmilling device easily installs on the shaft or bushing of your fan drive system to prevent reverse rotation. Maintenance-free and featuring a low-profile design, AirBrake^® makes your fans safer to maintain while extending the life of your drive systems.

FRP and Anodized Blades
When specified, we can provide FRP or anodized aluminum blades on select models.

ATEX Certified Tips
In hazardous or potentially explosive atmospheres, our plastic ATEX certified tips ensure safe and spark-free operation.

Root Seals
Riveted onto the root of the blade, the seals prevent water and other contaminants from entering the body of the blade.

Extended Hubs
Extended hubs allow for greater clearance between the fan and drive system, which makes them ideal for installation directly on the motor or gearbox and in a wide range of aftermarket situations.
