Hello,

I searched and don't see an answer to this question anywhere in the forums. The question is, I am specifying a fan to move a flammable vapor. The vapor stream will be inerted with nitrogen, so the fan will see flammable vapor plus nitrogen (oxygen will be held below the LOC). I want spark resistant construction but don't know if I need AMCA Type A, B. or C. I understand the differences between them, just don't know what criteria is used to decide which one to specify. Thanks for any help.
 
The "Which Type Should I Use" section was very helpful. Thank you.
