Industrial roof ventilators

Unlike the goss neck, the Maximum penthouse was designed to evacuate great volumes of air while still protecting the building from weather infiltrations, even in high gust of winds. Its unique storm proof system prevents infiltrations while at the same time capturing the wind flow from all directions. A chimney is created preventing moisture heat build-up within the attic space.
