Purge Gas Generatorfor up to 60 lpm of dry, CO2-free air
 | |
Compact, regenerative purge gas generators capable of delivering up to 2 scfm (60 lpm) of dry, CO2-free air with a dewpoint of -100°F (-73°C) and a CO2-content of less than 1 ppm. Ideal for FTIR spectrometer purge and emissions monitoring applications. Units come standard with an inlet particulate filter, inlet coalescing filter, purge mufflers, and outlet filter-regulator assembly. Accessories include a moisture indicator, sound suppression kit, flow meter, and surge tank.
Product Features:
- CO2-free air to less than 2 ppm
- Ultra-dry air to better than -100ºF/-73ºC dewpoint
- Continuous self-regenerative operation
- Outlet flow capacities of 0.1 to 3.5 scfm (3 to 100 liters/min.)
- Operating pressures of 50 to 150 psig (345 to 1000 kPa)
- Compact, lightweight aluminum construction
- Low power requirement (35 watts)
- Standard purge mufflers ensure quiet operation
- Easy to install and no regular maintenance is required
- Ideal for laboratory, OEM and point-of-use applications

Principle of Operation:
Ordinary compressed inlet air is passed through
one layered desiccant bed where the water is
removed first, followed by the carbon dioxide.
The air then continues to the outlet side of the
manifold and on to the application. A portion of
the purified air is expanded through an orifice
and directed back through the off-line desiccant
bed, purging the accumulated H2O and CO2.
Every 30 seconds, a solid state timer and two
solenoid valves reverse the process. The result is
a continuous supply of dry, CO2-free air.
