This 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.

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.
