I was thinking of using a pair of gravity flaps sealing on a rubber covered frame (to stop the clanking when working). But there would be a lot of development time/effort to get it working. Sort of thing I was thinking about, 4" diam input/output, full bore up to a wind speed of 4mph, reducing to say 5% cross sectional area at 20 mph. pipes. Any ideas?

Why ever this is not a requirement of building regulations I dont know -- all this talk about energy efficiency and then they blast away a load of heat via a fan.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1643&Focus=19765#Comment_19765 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1643&Focus=19765#Comment_19765 Thu, 01 May 2008 11:36:48 +0100 chuckey Frank]]>
