Inquiry (采购产品): Exhausting Fan I have a 14,400 sq'building w/22' ceiling in which we manufacture wood flooring and paneling. Total space 316,800 cubic ft. I have a 38,000 cfm baghouse system, changing air in building every 8.37 min. Problem is hot air trapped near ceiling and workers at higher elevation machine stations. Do you have a round fan that would mount into an existing 42" inside diameter duct 16" long protruding through wall to outside. I would need louvers and if possible auto control by temp. An open 22' x 20' overhead door would supply additional makeup air when fan is engaged. Do you see any other possible problems with this scenario.
