Inquiry (采购产品): In plant room I need to provida an enclosure around a machine. The room would be approximately 16' x 40' and only needs to keep the dust down. We would probably add outside air handling. The ceiling and one wall need to be movable such that a 26' piece could be lowered onto the machine in the room. **** Hidden Message ***** Joe Kaufmann 54162 Company: Industrial Engraving Corporation E-mail: jkaufmann@industrial-engraving.com **** Hidden Message ***** jkaufmann@industrial-engraving.com
