    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!
