Safe alternative to high pressure gas cylinders.
Purifies on-site compressed air to produce hydrocarbon free air. (<0.1 ppm hydrocarbon content)
Useful as generating fuel air for Flame Ionization Detectors (FID) or as zero reference gas.
Produces up to 1000cc/min of zero grade air.

High efficiency coalescing filter removes oil, water, and particulates.◦ Located immediately following compressed air
line outlet.
Equipped with manual drainto eliminate any liquids thathave accumulated.◦ Filter housing should be
checked periodically.

A stainless steel housing with catalyst and heater is used to oxidize hydrocarbons into carbon dioxide.◦ Platinum catalyst assists in
oxidation of hydrocarbons tocarbon dioxide.
Catalyst module is largeenough to maintain upto 1000cc/min ofhydrocarbon free air.

High efficiency sintered metal filter removes particulate contamination.◦ 0.5 micron filter ensures particle-free zero air
delivery.

Intermittently drains compressed air at set time intervals.◦ Ensures that air stored in reservoir is moisture
free.◦ Eliminates need for daily flush of compressor
reservoir.
Auto Drain

Rack mounted generator units come equipped with extrafilter device which actsas a compressor muffler.◦ Removes excess moisture
buildup◦ Decreases noise generated
by compressor.

Air compressor andZero Air Generatorshould be located asclose as possible.◦ Maintains air quality
while minimizing pressure drops and pressure fluctuations.
Considerations
![Page 11: Zero Air Generator](https://reader031.vdocument.in/reader031/viewer/2022020202/577cb5781a28aba7118d2e2f/html5/thumbnails/11.jpg)
Generator should be located indoors and free of excessive dust or dirt.◦ Ambient temperature around generator must be
between 60°F and 100°F (16°C and 40°C). Refrain from using plastic tubing
downstream from the generator.◦ Plastic tubing may cause outgassing and lower
the purity of the air.◦ Stainless steel tubing is recommended after
leaving the last filter.
Considerations
![Page 12: Zero Air Generator](https://reader031.vdocument.in/reader031/viewer/2022020202/577cb5781a28aba7118d2e2f/html5/thumbnails/12.jpg)
Once the compressor is turned on, allow the compressor to collect air.◦ Filling the reservoir takes approximately 5 minutes.◦ Once the reservoir is full, compressor will shut off.
Adjust the pressureregulator at generatorinlet.◦ Typically set at 30psig for
fuel air. Adjust the pressure
regulator at compressor outlet.◦ Typically set at 60psig for
actuator air.
Start Up

When powering on the generator for the first time, allow the hydrocarbon catalyst module to warm up.◦ This process typically takes 45 minutes.◦ Using air before the module warms up can result
in hydrocarbon content greater than 0.1ppm. Leaving the generator on continuously is
recommended.◦ Leaving the generator on prolongs the life of the
catalytic module.
Start Up

If an autodrain function is installed, set the interval and time length of drain.◦ Time length is measured in seconds (1–30 seconds).◦ Interval length is measured in minutes (1-60 minutes).
Start Up
![Page 15: Zero Air Generator](https://reader031.vdocument.in/reader031/viewer/2022020202/577cb5781a28aba7118d2e2f/html5/thumbnails/15.jpg)
Make sure enough time is allowed for hydrocarbon catalyst converter module to warm up before using air.
Routinely check the prefilter for any water or oil in the bulb and drain as necessary.◦ If compressor is located in an area with relatively
high moisture content, consider an extra stage of prefiltration to prolong filter and generator life.
Always ensure ambient air that compressor is storing is dust and dirt free.
Troubleshooting
![Page 16: Zero Air Generator](https://reader031.vdocument.in/reader031/viewer/2022020202/577cb5781a28aba7118d2e2f/html5/thumbnails/16.jpg)
If no air is flowing out of the outlet line, make sure inlet regulator is set.◦ If not enough pressure is being supplied to instruments,
increase inlet pressure.◦ Do not exceed 30psig for fuel air.
*THA fuel air max inlet pressure is 30psig.
◦ Do not exceed 60psig for actuator air. If no autodrain is installed,
draining the compressorreservoir daily is recommended.◦ Prevents moisture from
accumulating inside reservoir.◦ Prolongs life of prefilter to
air generator.
Troubleshooting

If poor air quality is being delivered, check ambient air for:◦ Chlorinated hydrocarbon compounds◦ Chlorofluorocarbons / Freons◦ Sulfur compounds◦ Phosphorous◦ Lead◦ Heavy metals◦ Long chain polymers
These compounds can permanently damage the hydrocarbon catalyst converter module.

Prefilter cartridge requires replacement every year.
Hydrocarbon catalyst converter module requires replacement every 2 years.◦ Allow the generator to cool for at least 2 hours
before replacingthe module.
