I am looking for a hazardous location exhaust fan for a sewage pump room. I need it to be an inline mounted fan that will fit a 4" PVC pipe. I have done a lot of searching online with not much help. Any help appreciated. Thank You, Steve Wiese.
 
Last time I needed to do something like you described I used a haz loc. wall mount shutter fan and built a box around the inlet side and ducted to where it needed to vent from. Was probably a larger fan CFM wise than you appear to be needing but might be the direction you need to go with?
 
Another way to vent if the room, if it is closed up. Provide a non hazardous ducted blower fan, ducting clean air from a different clean source area into the room.

Then provide a duct or exhaust grill, large enough to exhaust the supply the fresh air being pumped into the room.

A mechanical contractor might be able to assist you in sizing an appropriate supply fan and exhaust duct or louver opening.
A 4" pipe sounds awfully small for a sewage pump room. An exhaust fan doesn't work well if it is not provided with a supply air source

Paint mixing rooms were often ventilated in this manner,. Supply pressurized clean air in, and an exhaust opening to a safe discharge area.
