CMN oil-free high-pressure screw air compressor, with an air supply pressure of 20 to 40 bar, can be adapted to high-standard gas processes such as PET bottle blowing and blow molding. The whole high-pressure oil-free air compressor does not contain any lubricating oil to ensure that the outlet compressed air is oil-free. The screw-type air end performs two-stage compression with low vibration and noise. As one of the best oil free compressor suppliers, CMN oil-free high-pressure air compressor adopts an advanced two-stage dual-drive design and is equipped with two permanent magnet variable frequency motors with an efficiency of up to 97%. The inverter drive always supplies air with optimal efficiency. Maintenance is simple, only the air filter and water filter need to be replaced, reducing maintenance costs by 50% to 80%.

The working principle of the pure oil-free screw compressor is the same as that of the normal pressure oil-free screw air compressor. The difference is that the low-pressure screw air compressor is equipped with a low-pressure stainless steel air end with a compression ratio of 1.2 to 4, and the air supply pressure of the unit is 1.2 to 4 bar. The unit has good stability and low energy consumption.

CMN oil-free carbon dioxide reciprocating compressor, the air end is made of 304 stainless steel. If there are special requirements for the co2 screw compressor, 316 stainless steel can also be used to prevent corrosion. The inlet pressure, outlet pressure, and exhaust volume can be designed as required.

Relying on the low operating temperature of the air end, CMN, the hydrogen compressor manufacturers and suppliers, has developed a unique screw hydrogen compressor with a flow range of 5 to 59m3/min and a pressure range of 4 to 45bar. Since water is directly injected into the air end for compression, the operating temperature of the host will usually not be higher than 45 degrees Celsius, so safety can be guaranteed.

The advantages of the CMN oil-injected screw compressor are reflected in its outstanding energy-saving effect and variable frequency performance. The unit is equipped with a high-efficiency permanent magnet variable frequency motor and variable frequency drive, which automatically adjusts the speed to reduce energy consumption. Maintenance only requires replacing the filter element and air compressor oil. The CMN oil-injected screw air compressor is designed with no wearing parts, making maintenance simple and the designed service life is more than 20 years.

The high-pressure micro oil screw air compressor crafted by CMN has an air supply pressure of 20 to 45 kg. The air end is lubricated with high-quality lubricating oil and has two stages screw compression air end, which can be adapted to most high-pressure compressed air supplies.
