Combination Airflow

With combination air flow, there are supply ducts located on both side walls (running from the very front to the very back of the work chamber) that introduce the heated air into the chamber near the bottom. This helps ensure the heated air is distributed evenly throughout the length of the work chamber. The air rises past the product in a vertical manner, to totally bathe the product. The air is returned to the heating plenum through an adjustable return duct located above the work chamber.
