FLEXXAIRE'S 3-IN-1 REVERSIBLE PITCH FANS

Reduce costly shutdowns due to plugged radiators, engine overheating and overcooling.

Flexxaire fans are the only fans designed as three systems in one.

The first system is simple, it replaces and replicates the normal duties of your standard fixed pitch fan (note: we have yet to replace a manufacturer's fan whose airflow could not be matched or exceeded).

The second system eliminates the problems associated with your fixed pitch fan (i.e.: debris build-up and overheating). It's our in-motion variable pitch system, which purges debris from the radiator and engine compartment. The purge occurs when an actuator inside the fan temporarily moves the blades into a reversed pitch mode, and reverses the airflow. This process can be activated manually or automatically (with a programmable timer), while the engine is at full operating speed. All Flexxaire fan blades are configurable between 15 and 40 degrees of pitch in both directions.


The third (optional) system is our temperature control feature. No other fan can help warm engines more quickly and keep them at optimal running temperatures in low ambient conditions. This feature is exclusive to Flexxaire, as our fan blades rotate through the zero, or neutral position. By maintaining a neutral blade pitch, our fan creates a rotary air dam effect, which greatly reduces airflow, horsepower and fuel consumption. Either a Flexxaire temperature sensor or the machine's Electronic Control Module signals are responsible for controlling this function.

Clean Radiators

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.

• No shutdown for manual radiator cleaning

• Increased Productivity

• Reduce the likelihood of fire in the engine department

• Cleaning on demand for extra unscheduled purging
