BS EN 16475-2:2017EN 16475-2:2017 (E) 6 1 Scope This European Standard covers electrically operated metal fans for chimneys that are able
29、to create a stable positive or negative pressure for the chimney. This European Standard covers fans installed inline in the connecting flue pipe (inline fans) or mounted on the chimney outlet (exhaust fans). This standard excludes chimney cowls (Terminals with aerodynamic characteristics). 2 Normat
