05FAQ
What you need to know about Nitrogen.
What is a Brevitair nitrogen generator?
It is an on-site nitrogen generator for fiber laser cutting. Connect compressed air and power, and it produces high-pressure, high-purity nitrogen on demand, with no cylinder changes and no liquid nitrogen refills.
What nitrogen purity and pressure do the NG25 and NG50 deliver?
Both models deliver 99.99% nitrogen purity at up to 200 bar (20 MPa), with oil content of 0.03 mg/m³ or less and a dew point of −30 °C.
Should I choose the NG25 or the NG50?
Choose the model whose flow covers the nitrogen your fiber laser uses. The NG25 delivers 25 m³/h (600 m³ in 24 hours) and the NG50 delivers 50 m³/h (1,200 m³ in 24 hours).
How big is a nitrogen generator and how much power does it need?
The NG25 measures 2150 × 1750 × 2160 mm, weighs 2,200 kg and draws 34.9 kW in total, including a 22 kW air compressor. The NG50 measures 3000 × 1980 × 2300 mm, weighs 2,900 kg and draws 54.8 kW in total, including a 37 kW compressor.
Where can a nitrogen generator be installed?
Indoors in a ventilated room, out of direct sunlight and rain, at +5 °C to +40 °C and up to 85% relative humidity without condensation. Standard supply is 380 V / 3P / 50 Hz, with other voltage and frequency options.
When can I buy a nitrogen generator and how much does it cost?
