Title: VARIABLE AIR FLOW VALVE
Abstract:
The invention relates to an air flow valve that is a self-balancing air flow regulator, and so can provide different airflows at different ports on a duct system over a variable pressure range. Accordingly, having the valves on multiple air duct ports helps balance whole ventilation systems. The invention also provides ducting assemblies and ventilation systems using valves of the invention.
