EPA designs and delivers all types of rooms to support most surface finishing processes and storage needs. Cabinets are constructed of heavy-duty, single-skin, 18-gauge, G-90 galvanized steel to provide complete structural integrity. Panels are pre-punched and easily erected using nut-and-bolt assembly. Insulated panels are also available depending on the type of application. With all our models, blowers, non-sparking tube axial exhaust fans, and ductwork are sized to deliver uniform air circulation. Standard control panels operate the fan, motor and lights (including electrical disconnect, magnahelic gauge, magnetic motor starter, fuse branch circuits).
