About 2H
2H is the most compact airfoil profile of the H hub family, fitting high efficiency into tight, small-diameter installations.
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 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.
2H can be produced at diameters from 222 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?
- Electric motor coolingAdds airflow where the motor’s own fan is not enough, keeping winding temperatures down.
- Hydraulic oil coolersKeeps a steady airflow across oil cooler cores in hydraulic power units.
- Condensers and evaporatorsMoves air evenly across condenser and evaporator coils in refrigeration circuits.
- Compressor coolingUsed on the oil and air coolers of screw and piston compressors.
