Axial fan turbine

Abstract

The turbine of the ventilation set has a simple design with blades (3) detachably attached to the hub (1), ensuring increased rigidity of the blade (3) mounting in the hub (1) and its quick and easy installation. The axial fan turbine has a mounting element (4) for each blade (3) in the form of an arcuate plate with a radius corresponding to the radius of the hub (1), which is provided on the inner side with two guides (9) located parallel to the hub axis (1), with a spacing corresponding to the spacing of the guide grooves (2) in the hub (1).
