DUCTING MADNESS!!!
**edit UPDATED 8-4-2003 If you can't see the pics, then go here.
It gets pretty hot here in SoCal, so I had decided to create a ducting system to pipe the hot air outside. Along with the ducting, I constructed a
muffler box for the back of the computer to silence the rear fan noise as well. I also wanted the muffler to be easily removed.
So without further adieu. . .
Muffler box in place.
Muffler box is built out of cheap pine board, painted black. The Plastic ducting hose is from Rockler Woodworking store. It is meant for dust
collection systems. There are lots of quick connect/disconnect adapters I bought for use.
Ducting to the Window
The Ducting is routed underneath a wall mounted shelf. Note that the exhaust port can be closed.
Fan Module
I initally used a 120mm Sunon. It was a low speed fan, but it has balance issues and is chattering like crazy. I used a thermal sensor board, so it
was kinda ghetto, wires hanging out and all(in progress pics to come). I replaced it with a better balanced 120mm fan with thermal sensor built in.
I ended up using a 120mm Papst Variofan. Much quieter now.
Heheh, more pics to follow...

Is this a 120mm duct ? Because I've been looking for a 120mm duct at local hardware stores and I can't find them. They're standardized for clothes dryers which use something else - I think 112mm or so.The Plastic ducting hose is from Rockler Woodworking store. It is meant for dust collection systems.
Also, it looks like you have a hard plastic piece connected perfectly to each side of your Papst fan, which in turn are connected to the duct on each end. What is it and where'd you find it ?
Nope, there is a window screen there. Now, heavy rainstorms are another issue. I am going to probably put a splash guard over the ducting hole. I'll show a pic of the outside view of the ducting hole later. It already has a good amount of "lip" hanging out to prevent minor water splashing from getting in. Again, I can always close the duct hole if I need to. Also, as often as it rains in Southern California, I'm not in a real big hurry.Keel wrote:wow looks pretty good. aren't you afraid of birds/rocks/leaves clogging the up the fan though?

It's not a perfect fit, it's a good centimeter or two smaller in diameter. As I mentioned, I bought it at Rockler Woodworking Store.marc999 wrote:Is this a 120mm duct ?

The closable port on the window is called a blast gate.
I had to modify the parts I used for the fan module. There isn't a pic on the site. Basically it's a much larger square than the one you see connected to the fan. I think it's the Jointer Dust Hood.
If you have a Rockler store near you, just ask for the dust collection hoses and adapters.

Muffler Box
Inside of Muffler Box
Lined the inside with 1" Sonex acoustic foam. I bought it from 2CoolTek. Cheapest price I could find where you could order smaller pieces of Sonex foam.

Yep, a nice screen is in place to keep the critter out. Still have to do something about rain.

Sweet duct work (now that I can see the pics)
Ed, thanks for pointing out that Rockler carries these parts. I had given up on ducting after checking Home Depot and finding nothing usable. I stopped by the Torrance location on the way home and it looks like they have everything I need for a muffler project I had in mind.
For the Jointer Dust Hood, did you cut the flanges off then use 4" quick disconnect fittings? Approximately how much did you spend on parts?

Yep, I cut off the flanges. I bought the one that is square and kind of "dished". I used an Xacto knife (be careful!) and scored the plastic over and over and then bent the plastic to snap it.Ginta wrote:Sweet duct work (now that I can see the pics)

Yep I used the quick disconnects, the one's with the threaded end.
All the parts cost about $70+ . Not cheap.

New 120mm Panaflo L1A Being installed.
Definitely quieter than the Sunon I used with about the same amount of airflow.
Unfortunately, even this fan has started the annoying buzzing (alot quiter than the Sunon, though. Can no one make a 120mm fan that doesn't have balance issues? I guess I'll have to give in and try the Papst Model 4412 FGLb next. The Papst Variofan I used didn't have the balance issues, but it didn't have enough airflow.
