DucoGrille Classic G 50HP

The DucoGrille Classic 50HP and the DucoWall Classic 50HP systems have been developed especially for intensive ventilation. The resistance factor of both systems is exceptionally low which allows large quantities of air to be introduced into or removed from spaces, using only a limited surface. Visual free area amounts to 88%, physical free area 68%.
