Oil Injected compressor are widely used in various industries to provide compressed air power. CMN oil injected screw air compressor adopts patented shaft sealless design to ensure that the air end will never leak oil. The unique single-screw type air end achieves twelve times of compression in one rotation, with high efficiency. The ultra-high machining accuracy allows the air end to achieve good sealing and lubrication effects by spraying only a small amount of lubricating oil so the oil content can be less than 2ppm to meet most usage requirements. OIL INJECTED SCREW COMPRESSOR VS RECIPROCATING PISTON COMPRESSOR Piston air compressors use the piston to reciprocate in the cylinder to compress the air. They have high noise and vibration and many wearing parts. After the piston rings are worn, the air volume will decrease causing the decreased efficiency.

APPLICATION OF AIR COMPRESSOR IN DIFFERENT INDUSTRIES Compressed air is widely used in various industries. Thus air compressor applications in industry are also very common. In addition to some major applications, air compressors are also the following industries:

OIL FREE SCREW & SCROLL AIR COMPRESSORS FOR ELECTRONICS AND SEMICONDUCTOR INDUSTRY The air compressor is one of the indispensable equipment in the electronics manufacturing industry, and its application and role are crucial to the development of the entire industry. Here we will discuss the working principle, application fields, and functions of electronics air compressors.

The characteristics determined by the partial pressure of water vapor in compressed air and the temperature of compressed air are used for cooling, dehydration and drying. While keeping the compressed air pressure basically unchanged, lowering the temperature of the compressed air can reduce the water content in the compressed air, and the excess water vapor will condense into liquid. The refrigerated dryer uses this principle to dry compressed air using refrigeration technology, so the refrigerated dryer has a refrigeration system. Refrigerated air dryer working Refrigerated air dryer how it works The refrigerated dryer sucks the low-pressure (low-temperature) refrigerant in the evaporator into the compressor cylinder. After the refrigerant vapor is compressed, the pressure and temperature increase at the same time; the high-pressure and high-temperature refrigerant vapor is pressed to the condenser. The higher temperature refrigerant steam exchanges heat with the lower temperature cooling water or air. The heat of the refrigerant is taken away by water or air and condensed, and the refrigerant vapor becomes a liquid.

Pure water instead of lubricating oil is used in air end for lubrication. Air end and all parts contacting with water are made of 304 food grade stainless steel. Compressed air passes TUV oil free test and also meets requirements of FDA and GMP. With no oil in the whole machine, maintenance is simple which only requires the replacement of air and water filter. Water injected screw compressor adopts a direct coupling method between the air end and the motor, resulting in high transmission efficiency. Due to the direct injection of water for cooling circulation, the unit operates at a very low temperature which is around 45 degrees Celsius. Working Principle Of CMN No Oil water injected compressor The single screw air end is composed of a main screw and two symmetrically arranged flat star wheels to form a meshing pair, installed inside the stainless steel shell. The screw's groove, the inner wall of the air end shell, and the tooth surface of the star wheel constitute the compression chamber. The motor directly drives the rotation of the screw shaft, which drives the rotation of the star wheel. The gas enters the screw groove through the suction port, undergoes compression, and is then expelled through the exhaust port on the air end shell. There are spray holes on the air end shell for injection of lubricating oil or water into the compression chamber, serving as sealing, cooling, and lubricating functions.

Pure water instead of lubricating oil is used in the air end for lubrication. The air end and all parts in contact with water are made of 304 food-grade stainless steel. Compressed air passes the TUV oil-free test and also meets the requirements of the FDA and GMP.

Relying on the low operating temperature of the air end, CMN 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 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.

CMN independently develops and manufactures various post-processing equipment for supporting air compressors, including gas storage tanks, filters, cold dryers and suction dryers, etc., to achieve the purpose of removing oil, water and filtering impurities.
