Multi-Wing TR11W Fan Blade

About TR11W

TR11W is a reversible profile reaching large diameters on the W hub, suited to wide drying tunnels and stores.

Thanks to their symmetrical section, reversible profiles work with the same efficiency when the fan direction is reversed. They give uniform results in wood drying kilns, crop stores and ripening rooms where the airflow direction is switched periodically.

The W series is designed for large-diameter impellers. The 5W, 6W, 7W, 9W2, 1W, 2W, 3W, 8W and TR11W profiles are mounted with W retaining plates and are used in cooling towers, large dry coolers, genset radiators and tunnel ventilation fans.

TR11W can be produced at diameters from 316 mm to 1,606 mm. Since modular profiles are cut in 1 mm steps, simply state the diameter that matches your existing shroud or venturi ring.
