I am searching for a good manufacturer for an inline fan that is rated for combustible vapors. The bid requires that it meet National Electric Code (NEC), Class 1, Division 1, Group D specifications. I would like to find one that does not require a large enclosure, something on the order of 12 to 15 inch cube. Please weigh in if you have experience with these fans. Thanks!
I stopped getting notifications for Listserv posts a while ago. Maybe AARST is not in favor of public discussions among radon professionals? I sent you some info via message on this site. If you do not get it, email me at michelleatfestaradondotcom
