Wind Cowl.

A particularly interesting and challenging project. Working with Designer Nic Bailey, the requirement was to produce a non-powered method for eliminating the chlorine odour from a large house with an indoor pool area.


The solution utilises negative pressure created by the flow of the wind over the cowl. The cowl will spin to face the wind and due to the laws of fluid dynamics will draw air from the pool room. An internal cone with a sealing face can be manoeuvred to regulate or close the air flow.

Constructed from aluminium with an internal structure in stainless steel, the cowl was a challenging build, standing at over 2.5M tall with a base diameter of over 4M. Accurate surface modelling, lofting and plate rolling were essential.
