I recently purchased Norvell's All-In-One Arena. I love their
solution and their hvlp systems so I decided to try the arena. I do not feel the extraction fans do anything at all. I expressed my concerns to my distributor, as they are the ones who talked me into the purchase after second guessing myself, and they passed my concerns along to Norvell. I never received any type of response. I originally used Scentual Sun's Overspray system and it worked great. It was just really hard for me to clean because I have the original one & the filters have to be removed from the top & my ceilings aren't that tall. So, I had to tilt it forward or lay it down (it weighs a ton!!). Their new system was really expensive so I tried Norvell's Arena:(
With the arena, u can barely tell the fans are on. With Scentual Sun's, you could feel the suction before you even stood in front of it.
