I. COMPRESSED AIR SYSTEM
The compressed air system of the dryer consists of a number of pneumatic pistons located throughout the dryer,
a Filter/Regulator assembly, and pneumatic control panel.
1. Air Pistons:
The pistons are actuated by solenoid and flow control valves that are
under computer control. The pneumatic pistons are used to:
• Tilt the dryer for loading and unloading.
• Open and close load and unload doors.
• Operate heat reclaimer.
• Operate the cool down damper and the intake air damper.
2. Filter/Regulator Assembly
The compressed air supply to the dryer is connected into the 3/8” F.P.T.
fitting located on the rear corner of the lower heat console. This is
connected to the Filter/Regulator assembly, which is located at the bottom
rear of the lower heat console section.
The Filter/Regulator assembly performs two (2) functions:
a) The filter removes most solids and liquid particles from the compressed air stream and traps
them in its bowl where this waste can be readily removed through the drain valve at the bottom
of the bowl.
The filter bowl
should be
cleaned monthly.
