This type of grille is used in supply and exhaust ventilation and air conditioning systems, designed for outdoor installation in air ducts or building openings in premises of various types and purposes.
External air intake grilles are made of aluminium profiles in the form of a frame and louvers that are horizontally positioned and fixed at an angle of 45° with a step of 35mm.
