Automatic reversible fan for radiator cleaning

With fast pitch reversing, in under one second, the Flexxaire Fan purges debris from the radiator and keeps it clean and operational at all times. It can be programmed to purge at automatic intervals or manually with the touch of a button. Reversing happens at full speed by hydraulic or pneumatic actuation of the internal cylinder rotating instantly the fan blades from a working position over the neutral into reversing and back.

Superior Airflow Control for Diesel Engines, maximum engine performance!

• No shutdown for manual radiator cleaning.
• Increased Productivity.
• Reduce the likelihood of fire in the engine department.
• Cleaning on demand for extra unscheduled purging.
• Flexxaire fans provide more net engine power!
• Less energy consumption leads to fuel savings!

Your engine is an opportunity. Our fan takes full advantage.

More than a reversing fan, the Flexxaire Fan System is the world's leading smart airflow system.

Looking to install Flexxaire on your machine or integrate Flexxaire into a new design? We've made it simple to start.

The Flexxaire Fan System

Provides total control of airflow, keeps radiators clean, maximizes engine performance, saves fuel, and is robustly built and maintenance free.

Fan Blades

Flexxaire’s fan blades are designed and built for extreme conditions and high performance. High quality glass filled PAG (nylon) material allows for high temperature ranges from -40°C to 110°C as well as high tip speed, i.e. up to 20,000 FPM.

The design of the blade shape is optimized to deliver maximum airflow and high static pressures needed to meet Tier IV emission requirements.

Variable Pitch Hub

Flexxaire’s in motion variable pitch hub allows the fan blade pitch to be adjusted at any fan speed.

All hub components are machined from solid material to ensure perfect balance without any voids or porosity in material structure. All joints are sealed with high-quality O-rings. The mechanical spring loaded fail-safe feature ensures maximum airflow if control is lost. Perfect Pitch Sensor provides accurate pitch feedback and is designed to last longer than the engine – operating up to 20Gs of vibration, from -40° to 120°C temperatures, and exposure to debris and caustic fluids.

Controls

Flexxaire controls are flexible, feature rich, robust and integrate seamlessly with onboard electronics. The system can be as simple as reversing the airflow or as complex as temperature driven pitch control. We provide turn-key solutions or assist you to integrate our system into an existing controller.
