Spray booth fan, do I really need to worry about an explosion?

No more or less than I recieved from that person in the past.

Any who, moving on.

I suppose I should have said this earlier, since it is a closer answer to the OP’s question. I have a nice spray booth, but I only use it when I am painting with rattle cans. I do not use it for airbrush work- I just clear off the workbench a bit and work right there.

I agree that the amount of fumes from an airbrush is pretty small. I don’t think the thinners used with acrylic and even with turpentine (for enamels) is that dangerous in those volumes. I am not sure about lacquer thinner, though. I do try to reduce the volume of gases during the cleaning, however. I have a homemade “cleaning station” that traps the vapors of what I run through my airbrush while cleaning.

Hi Dan,

Would you mind describing this? I have long wanted to build one of these.

Thanks!

Well, I will have a chance to build a new one, so will take pictures while I do. My cleaning station sat on the edge of the bench right below where I keep my airbrush. I use a suction feed (bottle type) and the bottle adapter/bottle fell out when I picked up the airbrush day before yesterday. It hit cleaning station on way down, knocking both to floor, and destroying my cleaning station.

As a summary, since it will take a few days to make a new one:

I use a glass jar (because I sometimes clean with lacquer thinner. I make a necked top from 1/2 or 3/4 inch PVC pipe fittings, including a 45 degree corner fitting. A very short length of pipe comes out of that fitting, with a piece of plastic covering the end. A 5/16 inch hole in the end is just a bit bigger than the tip of my airbrush. I glue the pipe buildup in a hole I have created in the jar lid, and poke a little hole in the lid as a second hole, so the jar can vent pressure without competing with the incoming airflow. Takes a glass jar (pint or half-pint or so) and about a buck or two’s worth of pvc pipe fitting.

BTW, the station had several ounces of used thinner in it (which I save to put in my brush cleaning jar), and cleaning that off the floor was no fun!

You also forgot the 4th thing you need for a fire is static electricity I’ve been using the same fan in my paint booth since the early 70’s have had no probluems. My fan motor is as far as I know brush type motor,It’s the type used in furnace blowers. I can understand the concern here with all the new paints on the market that are no longer using a petroleumn base ie; lacquer base paints I think our biggest worry would be WEAR YOUR RESPERATOR when you spray.[2cnts] ACESES5
