I got a pre fab paint booth installed in my new shop finally but still need to run the duct work.The sales rep recomended running it straight up through the roof but the directions say one bend is possible with the standard motor that comes with the booth.I would like to go out the side of the building.My question is if I made a 90 degree turn will it cause too much turbulence in the pipe or do I need to use a 45?Do any of your booths have a 90 degree turn or straight out the roof?

I will bump this up but i dont know.. did you call the manufacture and ask if it would be alright to put in a 90??

Thanks king,I posted on the off topic area also and got the answers I wanted.The rep said no bends ,the directions said one bend is ok ,two bends or more require a larger motor.
