About 3Z
3Z is the slim, light airfoil profile of the Z family, giving balanced performance in medium-pressure condensers and coolers.
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.
3Z 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?
- Condensers and evaporatorsMoves air evenly across condenser and evaporator coils in refrigeration circuits.
- Dry coolersDelivers high airflow over large coil faces in dry coolers at low sound levels.
- Compressor coolingUsed on the oil and air coolers of screw and piston compressors.
- Electric motor coolingAdds airflow where the motor’s own fan is not enough, keeping winding temperatures down.
