I'm setting up screen printing equipment in the basement of a commercial building. The space is about 1500 square feet with no windows only a door. Is it necessary to vent out a smaller entry level dryer? The cost to do so is significant as I'd have to go through the main floor and then up through the roof with an exhaust fan. I have heard some people tell me that they don't bother venting out their dryers and then others tell me that I should do it because of the fumes that come from the dye in the fabric of the shirts and hoodies. Any suggestions or feedback is greatly appreciated.
