Spray Booth Exhaust Question

[John Hollaway]

Recently I've bumped into several finishing forum comments that suggested the idea of returning spray booth filtered exhaust back into the shop when spraying only waterborne finishes. This idea intrigues me somewhat because I regulate the temperature and humidity in my shop year-round and really dislike pulling cold or humid make-up airair back into the shop. If you or anyone you know of recirculates filtered spray booth exhaust, I would very much like to see that issue discussed further on this forum. Thanks.
