Abstract
Wentylator promieniowy do kanału wentylacyjnego ma lej wlotowy (1), a za nim wirnik (2) posiadający przednią tarczę (7) z otworem od strony leja wlotowego (1), tylną tarczę (8) i umieszczone między nimi łopaty robocze (9). Wentylator charakteryzuje się tym, że lej wlotowy (1) od strony wlotu powietrza wyposażony jest w co najmniej dwa elementy kierujące (5), a z przeciwnej strony połączony jest trwale z kierownicą aerodynamiczną (3), przy czym wirnik (2) znajduje się przynajmniej częściowo wewnątrz kierownicy aerodynamicznej (3).The centrifugal fan for the ventilation duct has an inlet funnel (1), and behind it an impeller (2) having a front disc (7) with an opening on the side of the inlet funnel (1), a rear disc (8) and working blades (9) placed between them. The fan is characterized in that the inlet funnel (1) is equipped with at least two guide elements (5) on the side of the air inlet, and on the opposite side it is permanently connected to the aerodynamic guide (3), the rotor (2) being at least partially located inside the aerodynamic steering wheel (3).
