Variable Frequency Oil Free Screw Air Compressor

Advantages:


1. High efficiency, high reliability, 100% pure oil-free compressed air, ideal isothermal compression, displacement: 0.8-45.0m³/min.
2. Technically superior electrical control system, caring and considerate maintenance instructions. Each unit adopts a microcomputer control system with self-diagnosis and protection functions. The multi-language liquid crystal display panel can display the actual operation of the unit. If the unit fails, the computer control system will respond accordingly according to different situations. The computer control system can prompt the user to replace parts and perform necessary maintenance in time. The computer system of the unit has a spare output, and the input terminal can realize interlocking control and remote control of multiple units. Guarantee to work safely for you 24 hours a day.

3. The original imported host has been verified in the market for nearly 20 years, and its air quality, energy saving and high reliability have all proved its advanced technical quality. Due to its perfect structure, it creates a fully symmetrical balanced compression, which has less vibration and lower noise. Completely oil-free air quality, replacing oil with water, realizing the four major functions of lubrication, cooling, sealing, and noise reduction, providing high-quality 100% oil-free air, pollution-free, and no special treatment for drained water, which meets environmental protection requirements. Due to the action of water, the compression is ideal isothermal compression, and the air volume per unit horsepower increases the output by 15% compared with the general dry compressor.

4. Ideal isothermal compression. Theoretically, when the air at 20°C is compressed to 0.7Mpa in an adiabatic process; since there is no cooling medium involved in the compression, the discharged air will be higher than 250°C. And we use lubricating water with cooling effect to inject the compression chamber, and the exhaust temperature will drop to 40℃, achieving high-efficiency isothermal compression. The moisture content in compressed air will also decrease due to the decrease in temperature. At the same time, the lubricating water will further take away the dust in the air.
5. In line with environmental protection requirements, the air compressor and other accessories are made of appropriate materials and treated to prevent rust. The compression chamber gaskets are also made of advanced materials such as ceramics and carbon fiber; high-precision water filters efficiently filter impurities to ensure The lubricating water maintains clean water quality.

Permanent Magnet Variable Frequency Rotary Screw Air Compressor saves more than 40% energy compared to conventional screw air compressors, using permanent magnet rare earth motors and high configuration spare parts. Low noise, because most permanent magnet variable frequency air compressors operate below the rated speed, resulting in less wear and noise on the main engine, and to some extent, extending the service life of the machine. The Aivyter factory manufactures Permanent Magnet Variable Frequency Rotary Screw Air Compressors with a power range of 7bar to 12bar from 10hp to 480hp
