JF Series Water-Cooled Two-Stage Screw Air Compressor

Power: 45-315 kWPressure: 7-10 bar

High-Efficiency Filtration System

High-efficiency oil-gas separator ensures oil content in discharge air is below 3 ppm.

High-precision oil filter guarantees optimal oil supply to the airend, providing better protection and extending its service life.

High-efficiency vertical air filter keeps the internal system clean, protecting the airend rotors and bearings from wear, and prolonging the life of the lubricating oil.

Two-Stage Air-Cooled Compression Unit

Horizontal structure with low center of gravity, low vibration, and more stable operation;

Integrated main unit and motor structure with 100% transmission efficiency (Patent No. 2014103573965);

Lower compression ratio compared to single-stage compression, less internal leakage, inter-stage oil injection cooling, approaching isothermal compression;

Achieves synchronous stepless speed regulation to meet various demands, with motor efficiency of 95.5%, 4.1% energy saving, high torque, and smooth operation.

Dual Inverter System — Constant Temperature & Constant Pressure

The electrical control cabinet is divided into independent hot and cold zones, enhancing the cooling performance of the inverters;

An enlarged radiator with anti-rust and anti-corrosion surface coating ensures easy cleaning, extended service life, and stable temperature control;

Low oil temperature prevents oil circuit coking, carbon buildup, and overheating issues;

The unit operates smoothly with extended lifespan, effectively avoiding shutdowns caused by high temperatures.

Intelligent Control System

Simultaneous intuitive display on-site, mobile phones, and computers, with synchronized views for users, service providers, and manufacturers showing operating status, operational data, fault warnings, etc.;

Real-time online monitoring of pressure, power, and temperature fluctuations.

Cooling System

Water, as a cooling medium, has a high specific heat capacity, enabling rapid and effective temperature reduction of the screw compressor to ensure efficient operation.

It features a compact size, low noise, and stronger adaptability to various environments.
