While we are on the subject, if using a pusher fan, can anyone recommed how many cfm is enough? Or is it a matter of getting the most you can? In other words, is there a minimum cfm fan one should have to be safe?
Not trying to hi-jack the thread, just thought this would be a good spot for some input on this air movement question.
By the way, Jim - I have had my pusher set up exactly the way you describe, and it has been successful.
Thank you!
Joe
