A nitrogen compressor is a device designed to pressurize nitrogen for transportation, storage, or industrial use. It has a wide range of applications across the national economy, particularly in industries requiring high-purity nitrogen.
Pressurizing nitrogen for laser cutting
Nitrogen acts as a shielding gas in laser cutting, preventing oxidation of metal workpieces and surrounding areas at high temperatures, thereby improving cut surface quality and cleanliness.
Nitrogen storage
For PSA nitrogen generators with outlet pressures ≤10 barg, storing nitrogen allows for cost-effective use, such as charging during off-peak hours or when the generator has high displacement.
High-pressure nitrogen compressors for cylinder filling can be air-cooled or water-cooled, and are available in single-acting or double-acting designs. The Fengpai series oil-free nitrogen compressors provide stable operation, high efficiency, energy saving, and long service life, and are widely used in nitrogen laser cutting, nitrogen canning, and chemical engineering.
1. Completely oil-free design – Eliminates any possibility of oil contamination in high-pressure, high-purity nitrogen.
2. Simple and user-friendly structure – Easy to control and operate.
3. No contamination to the compressed nitrogen – Maintains consistent nitrogen purity from inlet to outlet.
4. Fully oil-free design with stainless steel cylinders, eliminating oil contamination, maintaining stable oxygen purity, and suitable for VPSA / PSA oxygen source boosting applications.
5. Stable and efficient operation – Long service life with energy-saving performance.
