About 6H
6H is an increasing arc profile on the H hub, providing stable pressure in compact coolers with dense cores.
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 H series is Multi-Wing’s compact hub family. The 2H, 3H, 1H, 4H and 6H profiles are mounted with H retaining plates and cover roughly 222–742 mm. It is the series most often found on electric motor cooling, hydraulic oil cooler and compact condenser fans.
6H can be produced at diameters from 281 mm to 742 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?
- Hydraulic oil coolersKeeps a steady airflow across oil cooler cores in hydraulic power units.
- Electric motor coolingAdds airflow where the motor’s own fan is not enough, keeping winding temperatures down.
- Compressor coolingUsed on the oil and air coolers of screw and piston compressors.
