Nice little fan. I bought this for a custom airbrush spray booth and it works, but there are a few issues: - Very low suction for the spray booth. It's my fault for buying the 4" but if I don't spray *directly* into the intake while I'm painting the parts it won't pick up the excess and it gets exponentially worse once I go above 20psi Airbrush.- The fan controller doesn't really work, turning it half way gives the lowest speed, no problem for me as I run at 100% all the time, but it has to be mentioned ему около 10 месяцев, и он начинает очень легко вибрировать / дребезжать, но больше, чем когда я впервые получил его Я не буду врать, я подозреваю, что это скопление пигмента на лопастях, а не вина самого вентилятора, поэтому я не буду снимайте баллы dafür. Generell solltest du dir einen If you are looking for a fan for an airbrush booth, get a bigger one. A 6" 390 CFM fan should be fine for you. I will be buying a replacement for mine shortly after this review as it is 41% off in the offer is.
