With the cfm rate I think I won't need the higher cfm so I can get dwell time in the absorbant, and that should bring down the db. Once I get the variable control installed I will test. <div dir="auto">David<br><div dir="auto"><br><div dir="auto"><br></div></div></div></div><br><div style="font-size: 10pt;"><div dir="ltr">On Sun, Dec 27, 2020, 10:36 PM Brian Cox via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="font-family:Arial,sans-serif;font-size:10pt">That seems pretty good, I just got a couple of fans that are 580ma , 7Watts , 32.4 cfm , 55db <div><br></div><div>Brian</div><div><br></div><div><br><br>--- <a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a> wrote:<br><br>From: David Colombo via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><br>To: Personal Submersibles General Discussion <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><br>Subject: Re: [PSUBS-MAILIST] Scrubber design and materials<br>Date: Sun, 27 Dec 2020 21:39:00 -0800<br><br><div dir="auto"><div>Hi Brian, here is the data on the fan.
