b. Air Connection
Air connection to system – 1/8” N.P.T.
c. Air Regulation
No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 psi (5.51 bar)
must be provided. It is suggested that a regulator/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.

Steam Damper System Operation
The steam damper, as shown in the illustration below, 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 steam damper is in cool down mode as shown in
Diagram 2.
