BLEX®
zero-tip technology

BL1

More Power, Same Energy

BLEX® increases impeller efficiency by boosting static pressure—without extra energy consumption. Optimize blade pitch or reduce RPM while maintaining full performance.

BL2

Quieter, Smoother Airflow

BLEX® cuts noise by up to 6 dB(A) by reducing turbulence at the blade tips. The result? A quieter, more efficient system with improved aerodynamic flow.

BL3

Built for Real-World Demands

Made from advanced yachting-grade materials, BLEX® is designed to last. It absorbs momentary shroud contact, protecting fan blades and the drive shaft—perfect for mobile and industrial applications.

BL4

Reliable & Proven Performance

BLEX® exceeds industry safety standards, ensuring consistent, high-performance operation over time. Trusted by professionals where efficiency and durability matter most.

Winglets - molded to the blade tips improve cooling, boosting reliability and efficiency.

WL1

XXXXX

The winglets help to minimize turbulence by streamlining the airflow around the blades, allowing for a smoother passage of air.

WL2

XXXXX

The reduction in turbulence leads to optimized performance, as it increases the overall pressure and flow rate of the cooling system.

Smarter Cooling,
Greater Efficiency

EC1

Optimized Performance

Electronic clutches adjust fan speed precisely based on engine temperature, ensuring efficient cooling, reducing noise, and lowering fuel consumption.

EC2

Less Drag, More Power

By disengaging when cooling isn’t needed, these clutches reduce engine drag—boosting efficiency and fuel economy.

EC3

Durability & Smart Monitoring

Advanced diagnostics detect issues early, while electronic control minimizes wear, extending the lifespan of the clutch and cooling system.

EC4

Seamless Integration

Designed to work with modern engine management systems, electronic clutches enhance overall vehicle performance with real-time adjustments.
