4. Steam Damper Air System Connections
The dryer 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.
a. Air Requirements
There is no air requirement for dryers with the Electromechanical Steam Damper Option.
Shaded areas are stated in metric equivalents
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.
