About EMAX4
EMAX4 is an efficiency-focused airfoil profile in the Z hub family, standing out where energy consumption is critical.
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.
EMAX4 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.
