1. A small dimension throwaway turbine device for the checking of breathing flux, characterized in only three components realized in one single printing and injection production phase out of plastic material, making use of always the same raw material, comprising:
- a mono-block mobile equipment (2), configured to rotate about a rotation axis (5), formed exclusively of a plastic material; and
a turbo-turbine (4), with an inlet deflector (1) and an outlet deflector (3), the inlet deflector (1) and the outlet deflector (3) formed exclusively of the plastic material,wherein the mobile equipment consists of one single piece of the plastic material formed as a blade (2), a first extension, and a second extension, the first and second extensions extending from opposite edges of the blade along the rotation axis (5).

6. A turbine device for the checking of breathing flux, comprising:
-
a first deflector (1); a second deflector (3); and a mono-block mobile equipment sandwiched between the first deflector (1) and the second deflector (3), the mono-block mobile equipment consisting of a blade, a first extension extending from a first edge of the blade, and a second extension extending form an opposite second edge of the blade, wherein the first deflector (1), the second deflector (3), and the mono-block mobile equipment are made of a same plastic material and made only of the same plastic material.
