About 1HR
1HR is the right-hand (R) blade of the Multi-Wing 1H profile; by Multi-Wing’s definition it turns clockwise when facing the airstream. Request a quote for single blades or complete impellers marked “1HR” at the blade root.
Sickle profiles feature a blade tip swept in the direction of rotation. This shape reduces tip vortices and gives noticeably quieter operation at the same airflow. They are ideal for condensers near residential areas and projects with noise limits.
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.
1HR can be produced at diameters from 281 mm to 702 mm. Since modular profiles are cut in 1 mm steps, simply state the diameter that matches your existing shroud or venturi ring.
