CFM requirements for Heller 1500 reflow oven exhaust | 23 July, 2008

I just purchased a used Heller 1500 reflow oven for an SMT line that I am ting up. Looking for the CFM requirements for my exhaust venting. Does anyone out there have any information on what the minimum requirements are for pumping this exhaust out? Any help would be greatly appreciated.

100 CFM at each exhaust if you're using room air, 25 CFM/ea if you're using nitrogen (according to my manual...never used nitrogen myself) per their specified delivery rates.

It SHOULD be written on the machine. I have had/have 1500 Hellers that range from 60cfm to 500cfm
