Exhaust Ventillation

Exhaust Ventillation

Exhaust Ventillation

(OP)
I've installed an exhaust fan in my crafts room(10 inch outflow), and venting through an outside wall brings paint fumes back into my home through the windows. I want to run piping underground about 50feet out,(easy to do here) and 10" pvc is too $$$. Can I connect from 10" to 6" without compromising the efficiency much?? The fan is a 2000 cfm running medium speed.   

RE: Exhaust Ventillation

No.

Try 3 @ 6".

Hello Mike...thanks for your response. Your "NO" I assume means ...No you can't do that, it will effect the effiency greatly!! (??) But what do you mean by "try 3 @ 6"??? .....sorry if I'm a little dense here.

RE: Exhaust Ventillation

I mean three, or four, 6" dia PVC runs next to each other, in parallel.  You can use a plenum to join them at the fan end, i.e., the blower exhausts into a box that has multiple outlets.

Or just buy an activated charcoal filter.

Now I get it...Thanks Mike....I'll try the 3pcs of 6" out of a box.

RE: Exhaust Ventillation

What static pressure is your fan rated at for 2000 CFM?

Depending on your fan you may not get the flow you want if you have to run the duct 50 feet.


Could you turn the duct vertically and discharge it a few feet above the roof peak, using galvanized duct instead?
