6.3.1 One-Pass Airflow System
To operate with a One-Pass Airflow System, the air intake and exhaust dampers must be fully opened.
When the intake damper is fully opened, it will totally close off the recirculation path to the conditioning
plenum from the left duct wall. Fresh ambient air will be drawn into the blower wheel inlet and then heated as
it is forced through the heater bank.
Heated air will be discharged up into the right duct wall and into the workspace. It flows horizontally across
the workspace to condition the product and exits through the left duct wall. Since the recirculation path is
blocked by the intake damper, 100% of all process air is forced out of the exhaust port. No air is recycled.
This system will permit fast drying times, purge process vapors, and allow near ambient operation.
6.3.2 Full Recirculated Airflow System
To operate with a Full Recirculated Airflow System, both the intake and exhaust dampers must be fully
closed. 100% of chamber air will be recirculated. This system allows rapid heat up rates and better
temperature uniformity than with the One-Pass System.
6.3.3 One-Pass & Full Recirculation Airflow Diagrams
Important Note: The airflow diagrams shown above also apply to the Model DC and DCW Ovens when the
ASTM air intake and exhaust ports are employed. The only differences in the diagrams would be the drawing
of the dampers themselves.
