Wilkerson Manual In-Line Desiccant Dryers
Dial-air regulators feature a transparent, pressure-calibrated, non-rising adjustment dial for quick adjustment of secondary
pressure. The full reduced pressure range can be dialed in less than 270° of dial rotation. This feature is particularly
advantageous if secondary pressure must be changed frequently. Dial air regulators can be mounted in any position so dial face
is always visible. All dial-air units have a slight constant air bleed.
See pages 236-238 for regulator accessories.

Applications:
•
Manual air dryers are used to remove water vapor from compressed air systems, in applications such as paint spraying,
laboratory instruments and small control air systems. Filtration for absorber type dryers is important to protect the desiccant
bed from contamination. Cleaner incoming air will result in better performance, longer life and fewer service problems. To
regenerate silica gel desiccant, it must be heated to at least 350°F for approximately 3 hours or until color has changed from
pink to blue. Allow desiccant to cool to room temperature before pouring back into unit bowl.
An after-filter should be placed downstream from the desiccant dryer to ensure solid contaminants such as desiccant
dust do not migrate downstream.
