About 3HL
3HL is the left-hand (L) blade of the Multi-Wing 3H profile; by Multi-Wing’s definition it turns counter-clockwise when facing the airstream. Request a quote for single blades or complete impellers marked “3HL” at the blade root.
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.
3HL 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.
