Abstract (en)
The ventilation device with a radial air flow solves the problem of supplying premises with fresh air with an increased air outflow, improved efficiency and lower noise levels. The ventilation device comprises an air duct (1) with variable circular section, consisting of three successive parts and an accommodated inside it axial fan (2). The tird section of the air duct (1) expands like a funnel and together with a coniform baffle (3) forms a radial air passage. The coniform baffle (3) is arranged after the fan in the direction of the exit for the air and represents a truncated cone with gradually increasing diameter. A streamlined member (4) is arranged in front of the hub of the fan (2).
