1.0 Introduction
This manual provides information on installing and operating
your Terra Nitrogen Generator.
By studying this document carefully, you can be assured of a
long, efficient service life from your system.
2.0 Description
Terra Universal’s Nitrogen Generator is designed to provide
reliable dry nitrogen without the expense and inconvenience
associated with bottled systems. It uses efficient membrane
separation technology to generate nitrogen from compressed
air (see the chart below for typical system performance).
The system contains a gas pressure regulator and indicating
gauge, a flowmeter, a 1-micron air-line coalescing prefilter, a
0.01-micron air-line coalescing filter, and the air separator
membrane module. The prefilter removes all solids 1 micron
and larger, along with water droplets and most oil aerosols.
The coalescing filters remove solids 0.01 microns and larger
and 99.999+% of oil aerosols, thereby protecting the
membrane module from oil and other impurities in the
incoming air-line and ensuring a long service life. Oil and
moisture condensation from the prefilter and coalescing filters
exits the system through a 1/4" slip-fit connector that can be
directed to an in-house drain.

3.0 Set-Up and Operation
Before operation, carefully unpack and inspect the Nitrogen Generator. Any damage should be reported immediately
to the shipping company.
To prevent dangerously low oxygen levels and risk of asphyxiation, nitrogen-purged systems should only
be installed in a well-ventilated area.
WARNING
Connecting and Operating the System
1. With the pressure regulator (counter clockwise rotation) and flowmeter (clockwise rotation) completely closed,
connect the Nitrogen Generator to an incoming compressed air line by means of the 3/8” (5/8” for Cat. #2700-
09B) inlet slip fitting on the top panel. The compressed air fed into the Nitrogen Generator should be regulated
externally between 100 and 200 psi (For maximum purity, choose the highest inlet pressure possible.)
2. Connect the nitrogen outlet by means of the other 3/8" (5/8” for Cat. No. #2700-09A) quick connect fittings on the
top panel.
3. Open regulator (completely clockwise) and flowmeter (completely counterclockwise) to allow unrestricted flow at
full line pressure. The outlet pressure will drop roughly 20-30% from the inlet pressure as the compressed air
flows through the membrane. Flow and purity are determined by adjusting either the pressure regulator or
flowmeter.
If consistent outlet pressure is required, set the pressure regulator at the desired level and then adjust the
flowmeter to achieve the desired flow at your selected pressure. The lower the flow rate at any pressure level,
the higher the product purity. The higher the pressure at any flow rate, the higher the product purity.
For your convenience, Terra installed a low-pressure alarm to alert users of gas line kinks or compressor
malfunctions via an easy-to-see Operator Status Indicator (OSI) light. This light emits a solid-color glow
under normal conditions and flashes if it detects that the compressed air feed falls below 70 PSI. This light is
120VAC powered and included as a convenience; electricity is not needed for the generator to extract
nitrogen from compressed air.
NOTE
Refer to flow tables on following pages for guidelines on typical purities achieved at varying pressures and
temperatures. Conduct purity tests to determine the settings that meet your specifications.
Initial Calibration
The frequency at which to replace pre-filters will vary depending on your application and system set-up. To help
determine the frequency for your system, check the pre-filter every three months until the color indicator on the pre-
filter turns yellow, which signifies that it’s time to replace it with a new pre-filter. Use the elapsed-time data from this
procedure to set up a filter maintenance schedule that corresponds to your workflow. By doing this, the membrane
filter will last indefinitely.

4.0 Maintenance
The membrane module inside the Nitrogen Generator is designed to operate maintenance-free as long as the prefilter
and coalescing filters effectively remove impurities (particularly oil vapor) from the feed air.
A slide indicator on these filters changes color (from green, to yellow, and then to red) when the filter element inside
either unit needs to be replaced (see Figure 1). This indicator should be monitored monthly. Under continuous use at
100 PSI, filters will operate for approximately two years (20,000 hours).
Replacing Filter Elements
1. Open the front housing panel of the Nitrogen Generator to expose the filters (see Figure 1).
2. Rotate the self-locking bayonet head 1/8 turn counterclockwise to release it from the bowl (see Figure 2).
3. Pull the filter element to release it from the head. Remove the bottom filter element cap.
4. Attach the bottom cap to the replacement filter element and push it into the filter head until it locks in place.
5. Rotate the filter head 1/8 turn clockwise to reattach it to the filter bowl. Close the front panel.
