Abstract

Wentylator kanałowy z układem grawitacyjno-mechanicznym i zabezpieczeniem przed ciągiem wstecznym charakteryzuje się tym, że posiada układ kanałów, które zwężają się w przeciwnych kierunkach współdzieląc przegrodę pomiędzy kanałami, przy czym kanał centralny (1) posiada wąski wlot napływu strugi i szeroki wylot, przy wylocie usytuowany jest wirnik z napędem mechanicznym (3), przy czym kanał centralny (1) wyposażony jest w zawór zwrotny (4) umieszczony korzystnie przy jego wlocie; zaś wokół kanału centralnego (1) umieszczone są kanały satelitarne (2), które posiadają szeroki wlot medium i wąski wylot, przy czym kanały (1) i (2) współdzielą ze sobą ścianki boczne.A duct fan with a gravitational-mechanical system and protection against backdraft is characterized by a system of ducts that narrow in opposite directions, sharing a partition between the ducts, the central duct (1) has a narrow stream inlet and a wide outlet, at the outlet a mechanically driven impeller (3) is located, the central channel (1) being equipped with a non-return valve (4) preferably located at its inlet; and around the central channel (1) are arranged satellite channels (2) which have a wide media inlet and a narrow outlet, the channels (1) and (2) sharing side walls.
