What Is an N2 Compressor?
An N2 (nitrogen) compressor is a specialized industrial gas compressor designed to pressurize nitrogen gas for various applications. Nitrogen compressors are essential in industries requiring high-purity, high-pressure nitrogen — from oil & gas processing and chemical manufacturing to food packaging and electronics production. Our compressors deliver oil-free, contamination-free nitrogen compression with exceptional efficiency and long service life.

Global Custom N2 Compressor Projects
Tailored nitrogen compression solutions delivered across industries and continents, engineered to meet the most demanding specifications.
Custom Application
A leading German chemical conglomerate required a custom-configured LW-series oil-free nitrogen compressor for their ethylene oxide production facility. The unit was engineered to deliver 42 m³/min at 1.0 MPa with explosion-proof motor configuration and ATEX-certified instrumentation for Zone 1 hazardous areas.
Ever-Power delivered the compressor ahead of schedule with full TÜV documentation. The oil-free design eliminated contamination risks in our catalytic reactor purge cycles, and the unit has operated flawlessly for 18 months with zero unplanned downtime. Their engineering team's responsiveness during commissioning was exceptional.
Custom Application
A major Saudi energy operator commissioned a 4MW-series ultra-large nitrogen compressor for their LNG liquefaction train expansion. The 900 kW unit was customized for desert climate operation with enhanced cooling systems, sand-resistant air filtration, and remote monitoring integration for their SCADA platform.
The 4MW-100/30 compressor has exceeded our performance guarantees in the harsh Arabian climate. Ever-Power's customization for high-ambient-temperature operation and their willingness to integrate with our existing DCS architecture made this project a success. We have since placed a repeat order for Train 2.
Custom Application
A Brazilian food packaging multinational ordered a compact ZW-series nitrogen compressor for their modified-atmosphere packaging (MAP) lines. The unit was tailored for food-grade nitrogen output with stainless steel piping, sanitary connections, and compliance with ANVISA pharmaceutical-grade gas standards.
We needed a compact, oil-free solution that could fit inside our existing production hall without structural modifications. Ever-Power's ZW-6/7 unit was the perfect fit—quiet operation, minimal vibration, and the nitrogen purity consistently meets our <3 ppm oil residue requirement. Their after-sales support in São Paulo has been outstanding.
Custom Application
A Korean semiconductor foundry contracted a DW-series high-purity nitrogen compressor for their 300mm wafer fabrication cleanroom. The system was customized with ultra-high-purity gas paths, electro-polished 316L stainless steel components, and particle filtration to <0.01 micron for sub-7nm process nodes.
Semiconductor manufacturing leaves zero tolerance for gas contamination. Ever-Power's DW-36/30 with custom UHP modifications achieved particle counts below our most stringent specifications. Their engineering team conducted virtual FAT via livestream during COVID restrictions, and the unit passed our on-site qualification in a single attempt. Truly world-class execution.
