X03 Manual In-Line Desiccant Dryers
Wilkerson FRL's
with transparent bowl
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
(177°C)
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.
Features:
•
will dry up to 4400 standard cubic feet of air
•
desiccant; good for approximately 440 minutes at maximum continuous air flow before
regeneration is required
•
silica gel changes from blue to pink to indicate the need to replace or regenerate the
desiccant
•
slotted bowl guard for visual detection of color change
•
no electrical connection necessary
•
provides atmospheric dew point of
-45°F (-43°C)
with dry desiccant at
100 PSI
and
70°F
(21°C)
•
maximum operating conditions:
- transparent bowl:
150 PSIG
(10.3 bar) and

R21 Dial Air Regulators
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.
Features:
•
0-160 PSI adjusting range
•
balanced valve design
•
relieving type
•
non-rising pressure adjusting dial
•
piston operated
•
two ¼" NPT gauge ports standard on models without gauge, one ¼" NPT gauge port
standard on models with gauge - can be used for additional outlet ports.
•
models supplied without gauge use a GC230 gauge
•
maximum operating pressure:
300 PSIG
(20.7 bar)
•
temperature range:
32°F
to
150°F
(0°C
to
66°C)
