PSA Nitrogen Generator High Purity Nitrogen Production Equipment For Laser Cutting Industrial Gas Supply

A game-changer for laser cutting quality. High-purity nitrogen ensures smooth, dross-free cut edges. The HDFD99.99-40 PSA Nitrogen Generator is a skid-mounted pressure swing adsorption nitrogen production unit built for fiber laser cutting lines that require a continuous 99.99% purity nitrogen supply. It produces nitrogen on site from compressed air, replacing cylinder and liquid nitrogen delivery with a stable, low-cost gas supply.

A must-read for laser processing enterprises: insufficient nitrogen purity directly leads to dross formation during cutting, oxidation and yellowing of weld seams, and low yield rates. Luoming's high-purity nitrogen generators offer a purity level of up to 99.9995%, with stable, adjustable pressure and a dew point as low as -40°C to -70°C — all monitored in real time. Featuring rapid startup and consistent gas output, these systems effectively enhance cutting precision and surface finish while reducing defect rates. Furthermore, they are energy-efficient, highly reliable, and compatible with laser equipment of all sizes. By providing a one-stop solution to boost processing efficiency and product competitiveness, they ensure a quick return on investment and complete peace of mind.

• 99.99% high-purity nitrogen output — meets the assist gas requirement of fiber laser cutting for stainless steel and aluminum, keeping the cut edge oxide-free and weld-ready.
• Laser cutting nitrogen supply system — outlet pressure is held stable within ±1% through the buffer tank and pressure regulator, so the kerf stays clean at high feed speed.
• Skid-mounted nitrogen generator — air compressor, refrigerated dryer, filters, air buffer tank and nitrogen separator are pre-piped on one frame; site work is limited to power and air connection.

Fiber laser cutting of stainless steel, carbon steel and aluminum plate; sheet metal fabrication; electronics and semiconductor assembly; chemical blanketing; general industrial nitrogen gas supply. Nitrogen and oxygen are widely used as assist gases in metalworking processes, including laser cutting, heat treatment, and welding. A reliable gas supply is essential to maintain consistent production, minimize interruptions, reduce gas procurement costs, and ensure production continuity.

• Shielding Gas for Metal Welding
• Heat Treatment
• Metal Annealing
• Metal Manufacturing

Clean compressed air passes through the carbon molecular sieve beds. Oxygen is adsorbed at high pressure while nitrogen passes through as product gas. Two beds alternate between adsorption and regeneration, giving a continuous nitrogen flow at constant purity.

OEM and ODM production, factory acceptance test before shipment, installation drawings, remote commissioning support, and spare parts supply for the full service life of the unit.
