Venting Suggestions for a Paint/Spray Booth?

[masterjedi322]

I recently picked up a spray booth so that I can paint during the winter months. I am trying to find the best way to vent it outside.

Just a summary of my setup; the booth is in my basement, which has a ground level window. I have considered just running some duct work out the window, but I'd prefer something somewhat permanent that doesn't leave the window open.

We also have our laundry stuff setup in the basement. I was considering connecting the booth to the dryer duct that runs to a vent outside the back of the house, but decided against this as I did not want flammable paint fumes going anywhere near a heat source such as the dryer.

I have considered two other options:
1) Install another vent near the dryer vent and run a dedicated duct for the booth outside. This is a little more complicated as I'd need to basically cut a hole in the wall of my house.

2) Run a tube from the booth to the dryer path. Cut a hole in the dryer duct and insert the booth tube inside so that both run outside through a single vent (think of it as a tube inside a larger tube). I think this will eliminate the possibility of the paint fumes getting back to the dryer.

I was wondering if anybody had any other suggestions or recommendations. Any advice would be much appreciated. Thanks in advance.

depending on the size of the booth, you could top it off with a hood/range/stove top vent cover. Switches already installed, wire in a plug. Instant forced air fan. Then you'd have to duct it outside. I'd suggest just cutting the 4 inch hole and use a dedicated vent. Best of luck.

I guess I should add that the booth already has a powered fan installed. It also has an adapter to connect it to a duct...I'm just trying to figure out how to get it outside.

Thanks for the suggestions.

I'd connect some of that metalic duct work like you use on dryers, hook the ductwork up to your paintbooth and just switch between it and the dryer...whichever when you need it.

A 4" dryer line seems awfully small for the air changes required for a paint booth. What about removing the window and installing the ductwork in the opening and adding a manual controlled damper?

Is this a walk in type booth?

No, this is a table-top type spray booth...approximately 3'x2'x2'. Your suggestion of replacing the window with a damper is an interesting one...I will keep it in mind.

Thanks so far for all the suggestions. Keep 'em comin'.

My dad is an old HVAC/R guy and that's what I did during the summers while in high school. Do NOT, I repeat, DO NOT connect the booth vent to the dryer vent. It's probably against building code and you could have issues with lint from the dryer blowing into the booth fan, and/or materials from the booth fan getting back into the dryer.

Get some flex duct from your home store (Menard's, Home Depot, Lowe's, etc.) and also get a piece of plywood or plexiglass that you can put into the opening when you lift the window up. Cut a hole in the plywood/plexi, close the window on top of it, stick the vent pipe out the hole, connect other end to your booth fan. When not using the booth, compact the flex duct and the window "mount" and store it away. Much safer and easier.

Paradox is right. I wouldnt hook that up to any existing venting at all.

I built a full spray 'room' and used 2 high powered vents that vent out directly through the wall. We drilled 2 holes straight through for 4" duct pipes and installed the vents. I have 2 in the spray booth and 1 in the main room.

Here you can see the ducts on the ceiling, the support braces for mounting the vents and all the electrical..

And here they are mounted..

One more in the main room..

All of them have independant 4" ductwork venting them directly outdoors. They work like a charm. The suggestion above with the window sounds even easier and if it's close enough to your motor then it'll work like a charm.
