Glacier's nitrogen generators are designed to provide reliable dry nitrogen without the expense and inconvenience associated with bottled systems. They use efficient membrane separation technology to generate nitrogen from compressed air.

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 filter removes 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 filter exits the system through a 1/4" slip-fit connector that can go to an in-house drain.
