Our company produced many kinds of oil free compressor, inlcuding oil free air compressor, oil free gas compressor, including oxygen gas, nitrogen gas, hydrogen gas, natural gas, Argon gas, helium gas, Sf6 gas ects more than thirty kinds of gas medium,max pressure up to 40Mpa.
Bailian manufactures fully oil-free nitrogen booster compressors engineered for industrial applications demanding discharge pressures up to 35.0MPa and air displacement up to 1500Nm³/h. Our reciprocating piston nitrogen compressor systems deliver reliable, contamination-free gas compression for laser cutting, cylinder filling, food preservation, and chemical processing industries requiring pure nitrogen supply at elevated pressures.
Our nitrogen compressor portfolio encompasses multiple configurations optimized for diverse pressure ranges and flow requirements. The vertical sled-mounted compressor series excels in applications requiring compact footprints with discharge pressures from 250 to 350 bar, while our W-type and V-type skid-mounted models provide flexible installation options for facilities with space constraints. For laser cutting operations demanding 40-100 bar working pressure, our oil-free nitrogen compressors ensure oxidation-free cutting edges without post-processing requirements.
The nitrogen gas booster compressor functions as a downstream pressure amplification system, accepting pre-compressed nitrogen from generators or storage at suction pressures up to 1.0MPa and elevating discharge pressure 1.3 to 10 times the inlet value. This staged compression approach optimizes energy efficiency while preventing excessive heat buildup through multi-stage intercooling. Industrial clients benefit from our laser cutting compressors delivering flow rates from 4 to 1500 Nm³/h with purity maintenance throughout compression cycles.
Our nitrogen compressor systems incorporate fully oil-free lubrication technology utilizing PTFE piston rings and self-lubricating guide systems, eliminating hydrocarbon contamination risks in sensitive manufacturing environments. Single-acting reciprocating piston designs enable air-cooled operation with minimal maintenance intervals, reducing total cost of ownership over 20-year service lifecycles. Advanced PLC control systems monitor discharge temperature, inter-stage pressure differentials, and vibration parameters with automatic shutdown protection when operating thresholds are exceeded.
Compression efficiency peaks at 85-92% across rated capacity ranges through optimized valve timing and low-clearance cylinder designs. Multi-stage compression with inter-stage cooling maintains gas temperatures below 180°C, preserving nitrogen purity while extending seal and valve component lifespans. Our nitrogen compressor packages meet ISO 18623-1 safety standards for air and inert gas compression equipment, ASME B19.1 system safety requirements, and CE marking directives for pressure equipment, ensuring compliance across international markets.
Manufacturing facilities deploy our high-pressure nitrogen compressors for cylinder filling operations requiring 200-300 bar final pressures, with automated pressure monitoring preventing over-pressurization incidents. Food and beverage processors utilize nitrogen blanketing systems operating at 6-50 bar to displace oxygen in storage vessels, extending product shelf life while maintaining flavor profiles. Pharmaceutical manufacturers depend on our contamination-free compression for nitrogen transfer applications where trace hydrocarbon levels below 0.1 ppm are mandated by regulatory bodies.
Laser cutting operations consume 20-150 Nm³/h of assist gas at 15-25 bar pressure, with our oil-free systems preventing oxide formation on cut edges for aluminum, stainless steel, and copper materials. Chemical and petrochemical facilities implement nitrogen purging compressors for vessel inerting prior to maintenance activities, eliminating flammable vapor concentrations through continuous low-pressure nitrogen flow. Aircraft tire inflation systems specify our portable nitrogen compressors maintaining consistent 200-250 psi pressures resistant to thermal expansion during flight operations.
Two decades of manufacturing expertise in reciprocating compressor technology enables customized solutions matching precise pressure, purity, and flow specifications without oversizing equipment. Our engineering team collaborates with clients during system design phases, analyzing nitrogen generation methods, required discharge pressures, and duty cycles to optimize compressor selection and auxiliary equipment integration. Complete turnkey nitrogen compressor packages include air treatment components, pressure vessels meeting ASME Section VIII requirements, and automated control panels with remote monitoring capabilities.
24/7 operational capability stems from robust crankcase designs, premium bearing selections, and thermal management systems preventing oil degradation in cylinder assemblies. Maintenance intervals extend to 4000-6000 operating hours between major overhauls through precision manufacturing tolerances and advanced seal materials resisting high-pressure differentials. Global service networks provide rapid response for technical support inquiries, with comprehensive spare parts inventories minimizing production downtime when component replacement becomes necessary.

Q: What pressure range can nitrogen booster compressors achieve?
A: Our nitrogen compressor systems deliver discharge pressures from 6 bar for blanketing applications up to 350 bar for high-pressure cylinder filling, with suction pressures accommodating 0.1 to 1.0 MPa inlet conditions from nitrogen generators or bulk storage sources.
Q: How does oil-free lubrication technology work in nitrogen compressors?
A: Oil-free designs utilize self-lubricating PTFE piston rings and carbon-filled guide bearings eliminating hydrocarbon contamination risks, making them ideal for food-grade, pharmaceutical, and electronics manufacturing applications where trace oil content cannot exceed 0.01 ppm.
Q: What maintenance schedule applies to reciprocating nitrogen compressors?
A: Standard maintenance intervals occur every 2000 hours for valve inspections and seal replacements, with major overhauls at 8000-10000 hours including piston ring replacement and cylinder bore examination. Automated monitoring systems provide predictive maintenance alerts based on actual operating conditions.
Q: Can nitrogen compressors handle other inert gases?
A: Yes, our compressor designs accommodate argon, helium, and other chemically stable gases with similar molecular weights. Gas-specific seal materials and compression ratios are specified during ordering to ensure optimal performance and component longevity when compressing alternative inert gases.
Q: What energy consumption should I expect for nitrogen compression?
A: Power requirements range from 15-350 kW depending on flow rate and pressure ratio, with specific energy consumption typically 0.35-0.50 kWh per Nm³ compressed. Variable frequency drives reduce energy costs by 20-35% during partial load operation compared to constant speed motors.
