Exaust vent, Which One?

[James AKA Lynx]

I want to put in an exhaust vent high up on the side of my van. A smallish one that I could put one of the computer vans on to blow out hot air and cooking fumes. It should have a screen and be able to close and open easily. The fan should be able to be turned away from the vent to move the air inside when needed. <br><br>Roof vents are out. The 97 van does not have a smooth roof. Side/wall vent is needed.<br><br>Suggestions?<br><br>James AKA Lynx

&nbsp;Use one of those laundry drier exterior exhaust vents with the flap that closes when your fan turns off. I've used that setup before and it works. ..Willy.

This doesn't do everything you want, but I think they will fit a 90mm computer fan (I did not measure so I am not sure) &nbsp;Can be mounted on side or roof. &nbsp;<a href="http://www.etrailer.com/Enclosed-Trailer-Parts/Redline/9106.html" rel="nofollow" target="_blank">http://www.etrailer.com/Enclosed-Trailer-Parts/Redline/9106.html<br><br>T</a>hey also have low profile ones, but I don't know where you buy them.

Hi James I took an alluminium&nbsp; 45 degree down pipe elbow, from a standard home gutter system which fit a computer fan I had,&nbsp; exactly. The fan just pushed in and held snuggly. I then cut the elbow in half and put a hinge on it so it would lift up, fan blows&nbsp;inside, fold down to blow outside through vent. In my Van I have a vent that opens with a screen that are made of aluminium available from Mill Supplies under Grumman Olson Step van parts.&nbsp;The elbow fits into a stove top hood that i made out of two pieces of discarded pieces of gutter back to back. &nbsp;Hard to visualize/ explain, but if you click on my user name you will be led to my album if you look&nbsp;in the interior album,&nbsp;third picture in,&nbsp;&nbsp;you will see what I did, it is black.&nbsp;If you look on the exterior album you will see the type of vents I am talking about, on the top rear corners.

Can't help with the side vent, but do not think all computer fans are made the same.<br><br>They come in all different sizes and some fans can move more air, make less noise and use less current than others.<br><br>Variable speed fans are key. &nbsp;The Silverstone fm121 comes with a speed control, fully variable 33 to 110 CFM. &nbsp;0.08 to 0.40 amps and any point in between, and you can mount the speed control far away from the fan itself.<br><br>My single speed fans do not get much use, and when they do, it is when noise and current consumption are not factors.<br><br><a href="http://www.frozencpu.com/cat/l1/g36/Fans.html?id=hgx4kGaD" rel="nofollow" target="_blank">http://www.frozencpu.com/cat/l1/g36/Fans.html?id=hgx4kGaD</a>

Thanks. I like the butterfly vent. It does collect water if put on the outside. Putting on the inside would need another cover for the outside like the ones the frig's use. Anybody have a source for those?<br><br>James AKA Lynx

Here's the vent cover I installed ( http://www.fisheriessupply.com/vetus-denouden-scirocco-ventilator ) I haven't figured out the fan situation yet but the hole size is fairly common at 3 inches. I have a fiberglass roof and used a hole saw ( http://m.homedepot.com/p/Milwaukee-3-in-Bi-Metal-Hole-Saw-49-56-9670/202327741 ) to cut a perfect size. You'll need a pilot screw too, ask a worker to get you the right one. I was a bit freaked out about cutting into the fiberglass roof and put it off for over a month. Finally, feeling confident enough to give it a shot and after a couple of brisk drinks I was on my way. My advice, go slow. I know you're cutting into metal and I'm dealing with fiberglass so please, if anyone else feels the way I did it won't work on metal advise us all before there are multiple port holes. Hey, that might be a great way to drop some weight!
