PUFCO nitrogen compressors are primarily employed for boosting low-pressure nitrogen. Typically, nitrogen produced by PSA or membrane nitrogen generators operates at pressures of 7-10 kg, requiring compression to 15-45 kg for applications such as nitrogen shielding in laser cutting machines, nitrogen protection in chemical plants, and nitrogen shielding within the tyre manufacturing industry.
Completely oil-free, environmentally friendly and pollution-free, requiring no oil lubrication.
Friction seals such as piston rings and guide rings are manufactured from special self-lubricating materials that do not affect gas composition.
1. The entire compression system operates without thin oil lubrication, eliminating any possibility of oil contacting high-pressure, high-purity nitrogen.
2. The system features a simple mechanical structure, facilitating straightforward control and operation.
3. No contamination of the compressed gas medium occurs, with identical nitrogen purity at both the compressor inlet and outlet.
