So, I built another cab. This time I mounted the fan directly to the back of the box.
My fan is a Delta AFB1212SHE, which I can't find on their site. 120x120x38 on a voltage regulator. Stats for this model are: [FONT=verdana, arial, helvetica][FONT=verdana, arial, helvetica]151.85 CFM @ 3700 RPM, 53.0 dBA, 12.60 watts, 1.65 amps, Maximum Air Pressure 14.50 mm H²O[/FONT][/FONT]
My problem is the air rushing out the back of the cab. Even running at 4.5 volts the amount of air this fan moves is insane.
Does anyone have any ideas for quieting my exhaust? I just want to check to see if anyone has any proven methods before I start tinkering around and using up resources.
This was the idea I came up with first, because it's so simple. But would it decrease how loud it is?
There is a home made carbon filter on the inside of the cab attached to the fan. The extension on the back would either be cardboard, or 6" pvc elbow.
Any advice, comments, ideas, anything anyone can give me is very appreciated.
