Inert nitrogen generator Mini 5-50

high-purityfor productionfor heat treatment furnaces

Product overview
The Mini 5-50 nitrogen generator with integrated purge tank has been tested in collaboration with Formlabs in Germany. It provides a continuous nitrogen supply for the Fuse 1+ 30W printer and is suitable for materials such as Nylon 11 Powder and Nylon 11 CF Powder. When connected to a 6 bar(g) compressed air network the unit delivered 1.4 Nm³/h at a purity ≥ 99.5 %, matching Formlabs' purge requirements.

Application
Designed for inert gas purging to prevent oxidation during laser sintering processes on the Formlabs Fuse 1+ 30W. Recommended purge flow by Formlabs: up to 1.2 Nm³/h; the Mini 5-50 achieves 1.4 Nm³/h (adjustable purity) under specified inlet conditions.

Key features

• Integrated purge/storage tank for stable purge cycles
• Membrane-based nitrogen generation from compressed air
• Output compatible with Formlabs Fuse 1+ 30W requirements
• Adjustable purity up to ≥ 99.5 % (configurable to 99.9 %)

Advantages

• Eliminates need for high-pressure nitrogen cylinders on site
• Reduces operational costs for nitrogen supply
• Continuous on-demand nitrogen availability for production
