FRL's are designed for air service only, unless otherwise indicated.
SCFM ratings at 100 PSIG inlet pressure.
• 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 supply pressure: 300 PSIG (20.7 bar)
• operating temperature: 32°F to 150°F (0°C to 65.5°C)
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.

• 1.64 lb. bowl
• will dry up to 4400 standard cubic feet of air
• desiccant is 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
• provides atmospheric dew point of -45°F with dry desiccant
at 100 PSI and 70°F
• maximum operating conditions:
transparent bowl: 150 PSIG (10 bar) and 125°F (52°C)
metal bowl: 150 PSIG (10 bar) and 150°F (66°C)
• A standard airline filter and modular coalescing filter should
be used as pre-filters when using a desiccant dryer.
• no electrical connection necessary
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.
