Core Advantages

100% Oil-Free Design – Zero Gas Contamination

Utilizes PTFE-filled piston rings and guide rings for completely oil-free lubrication within the compression chamber. Eliminates the risk of oil contamination, ensuring the highest purity of output gas and meeting stringent requirements for food, pharmaceutical, and other high-purity industries.

Compact Structure – Space-Saving & Easy Installation

Features a V-type or W-type block design with a skid-mounted configuration. Compact footprint allows for flexible installation and easy system integration, perfect for space-constrained environments.

Multi-Stage Efficient Compression – Stable & Controlled Pressure

Employs 2-stage or 3-stage compression technology to increase pressure progressively and smoothly. Effectively controls the compression ratio per stage and discharge temperature, ensuring long-term reliability and extended service life.

Efficient Air-Cooling System – No Cooling Water Required

Equipped with a high-efficiency air-cooling system, eliminating the need for complex external water cooling circuits. Reduces installation and operational costs, especially suitable for areas with limited water resources.

Intelligent Control & Safety Protection

Includes automatic shutdown for overpressure protection, motor overload protection, and other smart safety features. Ensures equipment and process safety, with support for remote monitoring and automation integration.

Energy Efficient – Low Operating Costs

Optimized drive system and low-friction components significantly reduce shaft power and energy consumption, enabling cost-effective continuous operation.

Typical Applications

  • Industrial Nitrogen Systems – Supply, boosting, circulation

  • Chemical & Petrochemical Processes – Inerting, blanketing, transfer

  • Food & Beverage Industry – Packaging inerting, atmosphere protection

  • Laboratories & Research Institutions – High-purity nitrogen supply

  • Metal Processing – Welding, cutting shielding gas

  • Gas Cylinder Filling – Industrial & medical nitrogen cylinders


Operational Notes

  • Inlet gas must be dry, dust-free, and free of particulates; pre-filtration and drying devices are recommended.

  • Equipment should be installed in a well-ventilated, non-corrosive environment.

  • Regular inspection of belt tension, filters, and safety valves is required.

  • Custom voltage options available (220V/380V/415V/440V, 50/60Hz).

  • Delivery Lead Time: 30–40 days after contract signing and receipt of advance payment.
