4. Steam Damper Air System Connections
The ADS-78 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 at the
rear inner top area of the dryer just in front of the electric service relay box.
Compressed Air Supply Air Pressure
Normal 80 PSI
Minimum Supply 70 PSI
Maximum Supply 90 PSI
a. Air Requirements
MAN2497
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 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.
