Quieter spray booth exhaust fans?4/18
We are considering buying a larger spray booth (16' wide open face, 10' height) that will likely have a 5hp fan.
Our current booth is a 9' cube with a 2hp fan, and the noise (constant loud droning) is bad enough to warrant asking around if anyone knows of any quieter fan options available.
Most likely we would be buying a GFS open face, which is what we currently have, and otherwise like.
Roof height is about 14'.
put the fan on the roof, very easy to do
gfs sells a fan made by greenheck that is a lower db, but they charge up for it
frankly get a vfd and turn the speed of the fan down, cheaper and save you money in the winter time
There is lots you can do to tame the "beast".
Not sure if you can adapt it to your situation but a belt drive explosion proof variable speed fan is much quieter. They can also move just as much air. Direct drive fans are seriously loud. They're great for moving particulate matter you're moving mostly pre-filtered air.
This is just what I was looking for, thanks guys. I will look into each of these.
Our booth actually is a belt driven one, and the belt is a V-link belt (which also makes belt drives quieter) but that really didn't make much difference. I think our fan is just an older, noisier style.
I'm hoping we can locate the fan outside as well, that has been suggested to me by our vendor as well.
Bob, how many of the CLD tiles would you suggest? Did you guys basically cover the whole surface exterior, or just place a few in the most "floppy" locations, or a certain amount per square yard?
you will need to upgrade make up air too as you will be pulling twice the air. that will increase noise too.
Matt, we placed 8 CLD tiles in the center mass of each panel. Yes it will cost a few hundred bucks, but well worth it.
