Operating Temperature 40° to 140° F (4° to 60° C)
Min/Max Compressed Air Supply 150 to 175 psi (10.3 to 12.0 bar)
Dimensional data 7.5 x 20 x 46.5 in (19 x 51 x 118 cm)
Weight Model 450 100 lbs (45.36 kgs)
Model 650 120 lbs (54.43 kgs)
Specifications shown below are at an air temperature of 75° F (24° C) and a supply air pressure of 160psi (11.0
bar). These specifications are intended to be a baseline to result in the production of 95% pure nitrogen. The
output flow of nitrogen has been pre-set to 4.3 scfm (6.9 Nm³/hr) per membrane. Changes to air temperature,
supply air pressure or supply air flow will change the result of nitrogen purity.

CAUTION
Before using this product, read and fully understand operating
instructions and all decals on product. This is necessary to prevent
injury to operator and damage to product.
Do not attempt to use this product for anything other than its
intended purpose.
Use of this product should be in a suitably ventilated shop.
Operate valves slowly to prevent damage to coalescing filter.
Use of this product is only permitted in places free from explosion
or fire hazard.
Do not use this product if it is visibly worn, distorted or damaged.

INTENDED USE _____________________________________________________________
This Nitrogen Inflation System is a pneumatic device designed to generate deoxygenated air for the purpose of
inflating vehicle tires.
INSTALLATION INSTRUCTIONS _______________________________________________
1. Unpack and remove unit from shipping carton and pallet.
2. Inspect unit for any visible damage.
3. Make sure installation location is free from explosion or fire hazard and is suitably ventilated.
4. Make sure plumbing from air compressor to nitrogen generator is made of an appropriately rated copper,
steel or aluminum and is at least 30 ft. in length.
5. Install on a solid level wall.
6. Anchor unit to wall with 3/8 anchor bolts (not supplied) utilizing four mounting tab holes on back of unit.
7. Connect air supply line from compressor to air inlet on side of unit.
8. Connect nitrogen supply line to nitrogen outlet on side of unit.
9. Plug cord into standard 110 V outlet.
NOTE: The nitrogen generator has a filter system that captures oil, water and other contaminants.
However, if your air supply system generates an excessive amount of water, etc., it may be
desirable to install an air dryer.
NOTICE:
The presence of any oil in the Nitrogen Membrane will void the
manufacturer’s warranty.
OPERATING INSTRUCTIONS _________________________________________________
Turning Nitrogen Generator ON
1. Turn power switch on front of unit, from “OFF” position to “ON” position.
2. If unit is connected to a storage tank, an automatic shut-off valve will stop flow of air to the nitrogen
generator when tank pressure reaches 160 psi. The automatic shut-off valve will open again to allow air
flow through nitrogen generator when tank pressure drops to 145 psi. This is done to prevent
unnecessary use of air compressor.
3. To sample purity of nitrogen being produced, use a nitrogen analyzer at sampling port just as you would
check a nitrogen filled tire.
NOTE: After nitrogen line is pressurized or nitrogen storage tank is filled, vehicle tires can be inflated.
Turning Nitrogen Generator OFF
1. Turn power switch on front of unit, from “ON” position to “OFF” position.
Purity Adjustment Instructions
1. Your nitrogen generator is equipped with a purity adjustment dial. Nitrogen purity is set to a minimum of
95%. To increase nitrogen purity, rotate the purity adjument dial clockwise. Maximum travel of the dial will
be approximately 270°.
NOTE: Increasing nitrogen purity will decrease nitrogen flow.

MAINTENANCE _____________________________________________________________
NOTE: To avoid personal injury or damage to Nitrogen Inflation System, permit only qualified personnel to
perform maintenance. When cleaning or replacing filter elements and automatic float drains, shut
off supply air by turning power button on front of unit to “OFF”. Press pressure relief button on
front panel to exhaust all trapped air. You can now service the filters.
See repair parts breakdown for replacement parts.
ALWAYS: Keep Nitrogen Inflation System clean.
DAILY: Check the automatic float drain on all filters for proper operation.
If automatic float drain should become stuck open or inoperable, shut off air
supply (see NOTE above). Before servicing let pressure bleed off from filter.
Remove bottom cap from filter. Drain can be cleaned in hot soapy water. DO
NOT attempt to disassemble drain. If drain is still inoperable after cleaning, it will
have to be replaced. When installing a new drain, make sure o-ring is installed
on bottom stem before screwing it into the bottom cap. Finger tighten only.
WEEKLY: Clean automatic float drain on both filters.
See above.
BI-YEARLY: Clean particulate filter element and replace coalescing element.
