4. Steam Damper Air System Connections
The ML-200 is manufactured with a pneumatic (piston) damper system which requires an external supply of
compressed air. The air connection is made to the steam damper solenoid valve which is located on the outer
top, at the rear left hand corner of the dryer.
a. Air Requirements
b. Air Connection
Air connection to system --- 1/8-inch F.P.T.
c. No air regulation is provided with the dryer. External regulation of 80 PSI (5.51 bars) 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 insure that correct and clean air pressure is achieved.
5. Steam Damper System Operation
The MLS-200 steam damper, as shown in Diagram 1 on page 28, 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 tumbler (basket), allowing a rapid cool down.
Compressed Air Supply Air Pressure
Normal 80 PSI 5.51 bars
