axial fans
OZA 301
Low-and medium-pressure axial fans of the OZA301 series consist of a new design impeller, an all-welded casing made of rolled sheet and an asynchronous motor located in the casing. Thanks to its special aerodynamic shape, the motor support stand serves as a guide apparatus.
The impeller is made with variable-incidence blades, the setting angle of the blade is adjustable for maximum effi ciency. The volumetric blades are made by using injection molding. The air fl ow cross-section is maximized, which gives a signifi cant reduction in the outlet speed. Thanks to the new design of the impeller, the fans are designed with the highest static effi ciency at static pressure values of 100-900 Pa. The fl anges of the fan casing are edge-raised, providing increased rigidity and precision, and ensuring the same minimum radial clearance between the impeller blades and the casing along the perimeter of the impeller. The casing is made of aluminum, stainless or carbon steel.
