About 5Z
5Z is the widest-chord airfoil in the Z series, chosen for radiators and coils that need higher pressure.
Airfoil profiles have a wing-like cross-section and deliver high efficiency across a wide operating range. From 2H to 10G, this family covers the most widely used Multi-Wing profiles, from small motor cooling fans to giant cooling tower impellers.
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.
5Z can be produced at diameters from 222 mm to 1,261 mm. Since modular profiles are cut in 1 mm steps, simply state the diameter that matches your existing shroud or venturi ring.

Where is it used?
- Generator (genset) coolingKeeps generator engines at safe temperatures with strong pressure and airflow through the radiator.
- Dry coolersDelivers high airflow over large coil faces in dry coolers at low sound levels.
- Industrial process coolingServes cooling packages for transformers, compressors and process equipment.
- Condensers and evaporatorsMoves air evenly across condenser and evaporator coils in refrigeration circuits.
