One-Pass Air Circulation System: 

 
To operate with a One-Pass Air Flow 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 stack. 
 
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 damper. No air is recycled. 
This system will permit fast drying times, purge process vapors, and allow near ambient operation. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Full Recirculated Air Flow: 

 
To operate with a Full Recirculated Air Flow 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.
