Adjustable Air Intake and Exhaust Dampers:
Adjustable air intake and exhaust dampers are employed to vary air circulation between a One-Pass type
system and a Full Recirculated type system.
Both dampers should be slightly opened for the following conditions.
1. To remove undesirable exhaust vapors generated by the heating process.
An exhaust duct should be connected to the exhaust port and run to a location out of the building in
accordance with all local safety codes.
2. To promote faster drying times.
3. When operating near ambient temperatures.
Air friction caused by the blower wheel circulating process air causes a rise in chamber temperature.
This can not be controlled by the temperature controller. Both dampers should be opened wider as you
operate closer to ambient temperatures to purge excessive heat from the chamber.
