Inquiry (采购产品): air curtains I have two doors 21Ft. wide X 16Ft. high that have constant traffic through them. These doors are at the East and West ends of a 60' X 150' room that is being used for continuous inspection of a large product by 20 people. I need to provide some reasonable comfort zone for these operators. **** Hidden Message ***** Bill Lang 1550 Industrial Drive Stockton, CA 95206 USA Company: Dana Corp.
