GT ULTRA ZERO AIR GENERATOR
USER MANUAL

Version 1.03.0000
6.6 Connect Air Supply
The GT Ultra Zero Air generator requires a continuous supply of dry, oil-free compressed air with a pressure
between 4.5 (65.3 psig) and 10 barg (101.5 psig) for proper operation.
The air supply inlet pressure can be regulated with an adjustable forward pressure regulator, pre-set to 7 barg
(101.5 psig). The minimum allowable pressure is about 3 barg (43.5 psig); the maximum 10 barg (145 psig).
It is important that the air supply be maintained at room temperature and
dew point, and free of oils, hydrocarbons and particulates. If the compressed
air supply for the generator has excess moisture, oil or particulates, the inlet
filter may need premature replacement and the unit may be damaged. Install
extra coalescing and particulate filtration upstream from the unit if necessary.
6.7 Connect Output
• The output bulkhead of the GT Ultra Zero Air generator is located on the right side of the unit. It requires a
1/8” diameter fitting to attach the tubing or hose to the GC-detection system or analyzer air inlet port.
• In order to maintain the purity of the air from your GT Ultra Zero Air generator, stainless steel tubing or
instrument grade Teflon tubing should be used to connect the generator to the GC-detection system
or analyzer air inlet port. Copper tubing can also be used, but should be pre-cleaned or heated with a
propane torch while blowing nitrogen through it. All plastic hose should be instrument grade and free of
contaminants to avoid outgassing hydrocarbons or other pollutants over time.
•
Maximum outlet flow rate is 1.5 L/min with 7.5 barg (101.8 psig) inlet pressure and no external restrictions.
Actual outlet flow rate will depend on additional system pressure losses, if any.
WARNING: Maximum inlet pressure 10 barg (145 psig). Do not adjust the outlet
regulator on the unit without using an accurate pressure gauge (3-7 barg)
WARNING: The catalyst chamber can be contaminated
by high concentrations of lead, sulfur, phosphorous
compounds, heavy metals, chlorinated solvents and
chlorinated hydrocarbons. Extra care should be taken to
avoid introducing such compounds to the system. Any
contamination from oil, water or any of the substances
mentioned above will void the warranty.
WARNING: Do not use PVC or any other non-instrument grade plastic tubing
anywhere in your system. Many plastics will out-gas hydrocarbons and will
contaminate your purified air.
