Fan Blades
AVION fan blades ULTRA – The inexpensive and smooth-running ventilation unit for all types of stoves!
ULTRA fans are cast from one material (1.4864). The integrated reinforcement ribs lie on the centerline of inertia, which largely eliminates warping or twisting of the wings. ULTRA fan blades are always heat-treated, X-rayed and checked again for true running before delivery.
The service life of wings with 520 mm and 610 mm can be significantly increased by reducing the engine speed to 750 rpm.
