b. Air Connections
Air connections to system – 1/4” Quick Connection
c. No air regulation or filtration is provided with the dryer. External regulation and filtration of 80 psi (5.51
bar) must be provided. It is suggested that a regulator and filter gauge arrangement be added to the
compressed air line just before the dryer connection. This is necessary to ensure that correct and clean
air pressure is achieved.
5. Steam Damper System Operation
The steam damper, as shown in the illustration below (Diagram 1), allows the coil to stay constantly
charged, eliminating repeated expansion and contraction. When the damper is opened, the air immediately
passes through the already hot coil, providing instant heat to start the drying process. When the damper is
closed, ambient air is drawn directly into the basket (tumbler), allowing a rapid cool down.
Diagram 1 – shows the damper in the heating (open) mode, allowing heat into the basket (tumbler).
Diagram 2 – shows the damper in the cool down (closed) mode, pulling ambient air directly into the basket
(tumbler) without passing through the coils.
NOTE: With the dryer off or with no air supply, the damper is in the cool down mode as shown in the
illustration below (Diagram 2).
