  • We have several wood processing and assembly factories which have dust evacuation systems. We have relied on Jim Clark and his Team for all of our dust system needs. They have always been a pleasure to work with and have proven to me that they truly care about the quality of products and services.

  • I have used several vendors on dust collection equipment. Some not so good, some ok and one that particularly stands out. (Carolina Air) They have gained my respect through several transactions at a couple different facilities I have worked.

  • We have used Carolina Air Systems for several years now with both new installation work and with plant modifications to the existing system. We have been very pleased with the dust pipe quality and their installation crew. Also we are pleased with the Snap-It product because it makes it very easy when we have to move our machinery. We are very pleased with the products and service work Carolina Air does for RSI.

  • Carolina Air Systems has done several projects for us, and they have always been prompt, on schedule, and the quality has always been good. Jim has been an excellent source of information, and I would not hesitate to use them again.
