NMG Membrane Nitrogen Generator By Nano

The nano NMG membrane nitrogen generator produces a continuous, on-site supply of clean, dry nitrogen directly from your existing compressed air system. Using proven hollow-fiber membrane technology, it separates nitrogen from compressed air with no moving parts and no electricity required, delivering purities from 95% to 99.9% and flows up to roughly 2,500 SCFH. Stop paying for delivered cylinders and bulk liquid nitrogen and generate your own gas for a fraction of the cost, with a rapid return on investment.

How a membrane nitrogen generator works

1. Pre-treated compressed air enters the membrane bundle, which is made up of hundreds of thousands of hollow fibers.
2. Through a process called selective permeation, fast-moving gases such as oxygen, water vapor and CO2 permeate the fiber walls and are vented.
3. The slower nitrogen molecules travel through the center of the fibers and exit as a continuous, high-purity nitrogen stream.
4. Adjusting the outlet flow sets the purity: lower flow yields higher purity, higher flow yields more nitrogen at lower purity.

How to select your model

Nitrogen output depends on the required purity and the inlet air pressure. A larger model, or a higher inlet pressure, delivers more nitrogen at a given purity. Use the flow-by-model data in the nano NMG datasheet to match a generator to your required nitrogen flow, purity and available inlet pressure, and always include the recommended pre-filtration for reliable membrane life.

How much compressed air you need

A membrane generator is fed by your air compressor, so the feed air requirement is usually the deciding factor in sizing. Higher purity and lower inlet pressure both increase the amount of compressed air consumed per unit of nitrogen produced. Confirm your compressor has the spare capacity below before selecting a model.

Model	N2 at 99% / 100 psig	Feed air required	N2 at 99% / 150 psig	Feed air required
NMG 115	23 SCFH	1 SCFM	35 SCFH	2 SCFM
NMG 130	46 SCFH	2 SCFM	70 SCFH	4 SCFM
NMG 163	84 SCFH	5 SCFM	134 SCFH	8 SCFM
NMG 1126	168 SCFH	10 SCFM	268 SCFH	16 SCFM
NMG 1317	423 SCFH	26 SCFM	635 SCFH	38 SCFM

Feed air figures are approximate and are taken from the nano NMG specification table. Across the full range the NMG series consumes roughly 1 to 85 SCFM of compressed air depending on model, purity and inlet pressure.
