About 3CL
3CL is the left-hand (L) blade of the Multi-Wing 3C profile; by Multi-Wing’s definition it turns counter-clockwise when facing the airstream. Request a quote for single blades or complete impellers marked “3CL” 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.
3CL can be produced at diameters from 281 mm to 792 mm. Since modular profiles are cut in 1 mm steps, simply state the diameter that matches your existing shroud or venturi ring.
