Multi-Wing TR7Z Fan Blade

About TR7Z

TR7Z is a reversible profile on the Z hub, giving symmetrical performance in drying rooms where airflow is reversed regularly.

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 Z series is the most widely used Multi-Wing family, covering 3Z, 4Z, 5Z, EMAX4, 1Z, 2Z2, 7Z, 6Z and the reversible TR7Z and TR8Z profiles. Mounted with Z retaining plates in various blade counts and angles, it is common on condenser, dry cooler, compressor and genset fans.

TR7Z 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.
