Multi-Wing PMAX5R Fan Blade

About PMAX5R

PMAX5R is the right-hand (R) blade of the Multi-Wing PMAX5 profile; by Multi-Wing’s definition it turns clockwise when facing the airstream. Request a quote for single blades or complete impellers marked “PMAX5R” at the blade root.

PMAX is a family of high-pressure engine cooling blades for demanding off-highway, agricultural and genset applications. It offers higher airflow and pressure at the same power draw, with up to 3 dB(A) lower noise and up to 18% lower fan power thanks to optimised blade and hub geometry. It performs well in radiator packs with poor inlet and outlet conditions.

PMAX5R can be produced at diameters from 713 mm to 1,276 mm. Since modular profiles are cut in 1 mm steps, simply state the diameter that matches your existing shroud or venturi ring.
