I was in a down clothing factory and they had a room full of down with a hole in the wall and a house like on a vacuum cleaner going into a second room. The second room had a hole in the wall with a real shop vac on the other side. They would bring something to stuff into the second room, put the end of the hose inside a seam and someone would flip on the shop vac sucking down from the first room into the garment in the second room.
