Building ventilation moisture trap - has upwardly curved parallel sides offset to define flow chamber

摘要

The grease/moisture trap consists of upwardly opening curved parallel wings arranged in groups of two with open sides facing and so offset as to partly overlap the open sides at spacing and in so doing form an expanding flow chamber between wings and endwalls. The wings (3) are so deformed at the ends as to give a wall part (5) which is integrated with the wing and rises up off the deepest point of the wing. The wall (5) height is less than the wing radius and amounts to 5-6 mm from the deepest point of the wing (3). ADVANTAGE -Integrated side wings and endwalls form trap without solder-related toxic damage and hold fat and grease without leakage.
