Hello Technetters, Have anyone of you worked with BTU VIP 70 oven (without Nitrogen)? If yes, can you please suggest the Blower CFM for exhaust? One of our customers has installed 350cfm blower and is experiencing not-so-stable temperatures across the heating zones. I feel the exhaust might be the issue. Looking forward to your help.
