VENTILATION ARRANGEMENT
A housing for a ventilation arrangement, with a profiled rod providing a radial extension in each corner, with a pivotted guide vane extending between the rod and the remainder of the housing. In normal wind conditions this radial extension guides air into or out of the housing. In very high wind conditions the guide vane can however pivot and/or flex to release any excessive pressure caused by the high wind.
