NITROGEN GENERATORS
INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
3. GENERAL DESCRIPTION
The Parker Nitrogen Generators are completely engineered systems which will convert a compressed
air supply into a 95% to 99.5% purity compressed nitrogen gas. Nitrogen purities as high as 99.9%
can be achieved with significant reduction in output flow. The system is based on state-of-the-art
membrane separation technology. Hollow fiber membranes are used to separate air into a concentrated
nitrogen output stream and an oxygen enriched permeate stream. The model number of the generator
represents the approximate nitrogen flow in standard liters per minute that can be achieved at a
purity of 97% with a 100 psig (6.9 barg) outlet pressure. To achieve this outlet pressure, the inlet
pressure needs to be approximately 110-115 psig (7.6-7.9 barg).
4. ENGINEERED SYSTEM
The Parker N2-120, N2-160, and N2-240 Nitrogen Generators have been certified to IEC 1010
Standards (CSA 22.2 No. 61010-1-12). The generators bear the CSA safety marking on the
product label.
The Parker Nitrogen Generators include all the components required to generate high purity
nitrogen gas from compressed air. The user need only connect a supply of compressed air to the
inlet of the nitrogen generator and connect the outlet of the generator to the process requiring high
purity nitrogen.
The flow schematic (Figure 2) shows all of the major components of the system. The system can
be broken down into four primary functional groups. These are: prefiltration, air separation, flow
controls, and final filtration.
