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.

Compressed

Air Supply

Air Pressure

Normal

80 psi

5.51 bar

Minimum Supply

70 psi

4.82 bar

Maximum Supply

90 psi

6.21 bar

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.
