Spray Booth Venting Solids

I agree with Jim above. A furnace filter should trap perticulate matter. I have used a furnace filter for years without a problem.

I agree with all of the above posts. If you have a "good" paintbooth with a "good" filter, you should not have any particulate matter getting through. I use a homebuilt booth that has been used for many years and I have never had any solids getting through and marking up the window frames or house siding.

The booth is a recycled kitchen cabinet with a $2 furnace filter. My wife made a "sheer" curtain for the booth that I close when finished spraying but leave the exhaust fan running for a while to aide in drying the paint. This keeps the dust off the model. Every once in a while, she takes the sheer off and puts it in the wash to remove all the dust. If I keep a close watch on the sheer, I can tell whether the filter is doing its job or not. If it is getting clogged up, the draw from the fan is reduced and I can see the reduced inward curve of the curtain. Time to change the filter and the curve returns to the curtain.

The whole idea of the filter that came with your booth is to capture the solids you're concerned about. Some/most are sufficient as is. Some modelers have doubled that filtering layer up if they find the one not capturing enough.. You should have basically just fumes going out the vent tube.

 

I agree- something must be wrong with the filter- is it properly seated in the booth?  Even if it is clogged and needing replacement, you should merely get a reduction in flow, not large particles.  There is a leak somewhere.

Hi Andrew!

      Listen, did you know that you can buy at LOWES or HOME DEPOT filters especially for your use. They will be labeled for "Extremely Dust Prone areas". They work fine and yes, they are Furnace/Air Conditioner filters. They are designed to perform optimally in dust prone areas! You really don't need anything. If you feel you do, just remember this. The more you put in the airflow out the more suction you will need to pull the product out and away from the window. You won't paint your window Frames either way.
