NGM and NGM+ membrane nitrogen generators


NGM(s) and NGM+ membrane nitrogen generators to generate your own nitrogen on-site at low operating costs. Using innovative membrane technology, they adapt to your specific applications.

NGMs: Efficient nitrogen generation for low volume applications

The NGMs 1-3 range is a highly efficient nitrogen generator range utilizing membrane technology. These generators are designed to produce nitrogen from compressed air for a variety of applications. Purities range from 95% up to 99.5%.

Extremely fast start-up

After a push on the start button, the NGMs 1-3 only takes a few seconds to have your nitrogen available at the outlet.
• Nitrogen available right when you need it
• No specialist installation or commissioning

High performant membrane
• No ageing, our membrane keeps the full performance over the entire lifetime
• Long lifetime due to 2-stage pre filtration built in the generator

Cost savings
• Low operating expenses due to low air factor
• No additional costs such as order processing, refills and delivery charges.
• Low maintenance cost
