Downturn plenums enable an inline make up air unit to provide down discharge air. The downturn plenum is also insulated to reduce condensation build up and noise.

• G90 Galvanized steel

Use Downturn Plenums when inline modular units need to provide down discharge air. For example, all down discharge direct fired and electric heaters with DX cooling use the downturn plenum. All down discharge indirect heaters use downturn plenums.
