As an experienced manufacturer with long-standing industry expertise, Elily supplies durable 3 Nm³/h Mini PSA Nitrogen Generators dedicated to welding applications. Backed by our complete integrated supply chain, we deliver competitive factory-direct pricing to all partners. Adopting mature PSA technology together with imported high-performance carbon molecular sieves, this series of nitrogen generators achieves a nitrogen dew point as low as -40°C. The stable high-purity nitrogen effectively shields the welding pool to eliminate oxidation, weld discoloration and slag formation, producing smooth, flawless and visually appealing weld seams. Boasting a compact all-in-one structure, the unit requires no special foundation or civil infrastructure. It can be put into normal operation right after simple on-site installation.

As a professional manufacturer, Elily provides premium 1 Nm³/h Mini PSA Nitrogen Generators tailored for welding scenarios. Equipped with proven Pressure Swing Adsorption (PSA) technology and imported carbon molecular sieves, the machine produces qualified nitrogen with a standard purity of 99.99% within only 20 minutes after startup, and it can be upgraded to an ultra-high purity of 99.999% on demand. Purpose-built for laser welding, TIG welding and precision spot welding processes, the equipment supplies high-purity shielding nitrogen to completely isolate ambient oxygen. It avoids weld seam oxidation, yellow discoloration and black stains as well as slag accumulation, delivering smoother, cleaner and better-looking welding surfaces. This nitrogen generator runs fully automatically and adopts a compact structure to save workshop floor space.

Elily factory specializes in custom two-stage fixed-speed rotary screw air compressors with power ranging from 22kW to 315kW. The discharge pressure can be fully customized from 0.8 MPa to 1.6 MPa to adapt to diverse industrial air supply requirements. Adopting professional two-stage compression and intercooling design, the equipment achieves an optimized compression ratio and effectively reduces exhaust temperature. Matched with a direct-drive structure and fixed-speed asynchronous motor, the compressor delivers continuous, stable and pulsation-free compressed air output. The unit adopts standard forced air cooling system, controlling the exhaust temperature within 15°C above ambient temperature. The operating noise is maintained at 75–85 dB, meeting industrial environmental noise standards. Equipped with premium SKF bearings and high-efficiency precision rotor profiles, the compressor features long service life, stable operation and strong environmental adaptability. Widely applicable for medium and large industrial scenarios including textile, chemical, mining and food processing industries, this two-stage fixed-speed air compressor serves as a durable, reliable and cost-effective compressed air solution for mass production facilities.
