Compressed AIR Supply AIR Pressure | American Dryer Corp ML-75DII

a. Air Requirements

COMPRESSED AIR SUPPLY	AIR PRESSURE

Normal	80 PSI	5.51 bars

Minimum Supply	70 PSI	4.82 bars

Maximum Supply	90 PSI	6.20 bars

Shaded areas are stated in metric equivalents

b.Air Connection

Air connection to system --- 1/8-inch N.P.T.

c.No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 PSI (5.51 bars) must be provided. It is suggested that a filter/regulator/gauge (F/R/G) 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-75 steam damper shown in Diagram 1 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 2).

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.
