<div dir="ltr">Hi Brian,<div><br></div><div>If by "straight flow fan" you mean the geometry you would see on a computer cooling fan for instance, they are way less efficient for this purpose. I believe the reason is they move good volumes of air but develop very little pressure. I've tested both kinds, and the sort I'm using now has much better performance. Cliff has done similar tests and had the same results.<div><br></div><div>Best,</div><div><br>Alec</div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Apr 22, 2017 at 6:08 PM, Brian Hughes via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Just ordered a tank holder that has two bungies about an inch apart, used to strap tanks down on a boat. I'm thinking I can hang this scrubber from the roof using the aft most reinforcing ring, holding it up in the middle. If it works, straight flow fan.<br>
