About 6Z
6Z is the increasing arc profile of the Z series, offering a safe operating range on high-resistance radiators and oil coolers.
In increasing arc profiles the blade camber grows from root to tip, keeping the airflow stable even against high system resistance. The 6H and 6Z profiles represent this family.
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.
6Z can be produced at diameters from 316 mm to 1,255 mm. Since modular profiles are cut in 1 mm steps, simply state the diameter that matches your existing shroud or venturi ring.
