Industrial duct is a broad classification of ductwork that is used for many diverse jobs.  Usually associated with an industrial process, industrial duct can convey air or gases that may be corrosive or contain particulate with varying degrees of abrasiveness.

    There are 4 classifications of industrial duct systems: Class 1 (non abrasive), Class 2 (moderately abrasive), Class 3 (highly abrasive in low concentrations) and Class 4 (highly abrasive in high concentrations).

    Erosion of the sheet metal caused by the different abrasions results in a lower capacity for the Class 2,3 and 4 classifications.  Kruse Corporation has trained Union workers to handle any need. 

    Round duct is often used for ventilation and dust collection systems.  Despite round duct being easier to install and manufacture, there are systems that must use square duct.  Regardless of the situation, Kruse Corporation can fix your needs.  With a coil line in house to produce miles of square ductwork and a spiral line to create your unique spiral-round needs, Kruse Corporation can offer a great product for any situation.
