NGM⁺ 7-70 membrane nitrogen generator

Keep your costs low

Keep your costs low with NGM⁺ and its lowest total cost of ownership in its class. It requires 20% less feed air than a traditional generator and it does not need a wasteful feed air heater.

Reliable operations

NGM⁺ guarantees a continuous supply of dry, high-quality nitrogen with a stable purity to keep your operations running. A soft start protects membrane and extends lifetime.

Compact & silent

Quit operation allows you to install the machine on your production floor. No external tanks are needed for operations with stable flow.

Reliable on-site nitrogen generation with best-in-class performance

Membrane technology has traditionally offered high-quality, reliable on-site nitrogen generation. Atlas Copco’s new NGM⁺ 7-70 now raises the bar with an important additional benefit: low energy costs. The high-efficiency generator comes with the lowest cost of ownership available on the market today.

Keep your energy costs in check: the no-heater solution

Some membrane N₂ generators use a feed air heater to boost performance. However, these heaters use a lot of energy, inflating your operational costs. The NGM⁺ doesn’t require a heater to reach maximum capacity. The result: a substantial reduction in your running costs.
