GDHM Series
- Dual Tower
The GDHM Series desiccant
air dryers use the proven “Pressure Swing Adsorption” (PSA) method for
drying wet compressed air. This requires having two identical towers containing
hygroscopic desiccant. The unique design of the GDHM Series allows for
the dryer to start and stop with
a compressor or point-of-use equipment to eliminate purge loss when off.
The solid state memory feature allows the dryer to start where it left
off in the drying cycle to prevent wet air downstream.
• 3 - 50 SCFM
• Maximum Working Pressure:
150 PSIG
• Maximum Inlet Temperature:
120°F
• Pressure Dewpoints to

remote stop/start control
Design Advantages
• Solid state timer with
LED display for visual monitoring
• Built in timer memory
• Low velocity air through
the desiccant for more efficient drying
• Large internal air passages
to reduce pressure drop
• NEMA 4 Components (protects
against water spray and dust)
• Minimal threaded connections,
for fewer leak points than
competitive units
• Easy change out desiccant
cartridges
• Components are all easily
serviced and field replaceable.
(No special tools)
• Full repressurization
before tower switch-over causes less shocking
of the desiccant and no pressure fluctuation
• No Plug Mufflers (Will
not rupture or reduce dryer efficiency)
• 6-ft. Electric Power Cord
• 3-Year Limited Warranty
(parts only — excluding contaminated
desiccant and solenoid wear parts)
