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. <br> <br>OIL INJECTED SCREW COMPRESSOR VS RECIPROCATING PISTON COMPRESSOR <br>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. <br> <br>The oil injection screw compressor mainly consists of a screw and star wheels to form a compression chamber. The air compression process is completed through the rotation of the screw which has higher requirements for processing accuracy because higher accuracy means higher volumetric efficiency. The noise and vibration are small, the unit has basically no wearing parts so the maintenance cost is low. <br> <br>HOW DO OIL INJECTED AIR COMPRESSOR WORK？ <br>The main components of an oil free vs oil injected compressor are the air end, motor, oil and gas separation tank and cooler. Since the oil requires a higher temperature to ensure its good lubricity, the oil injected air compressor is generally air-cooled. The air is filtered by the filter element and then sucked into the air end for compression. <br> <br>Lubricating oil is injected into the air end for lubrication and sealing. The compressed oil and gas mixture is separated by the separation core in the oil and gas separation barrel to get compressed air with an oil content of less than 2ppm. After being cooled by the air-cooled cooler, the high-temperature oil returns to the compression air end and circulates continuously. <br> <br>For more information about difference between oil free compressor and oil injected compressor and a screw compressor, please feel free to contact us! <br>#oil#injection#screw#compressor <br>[a]https%3A%2F%2Fwww.cmncompressor.com%2Fproducts%2Foil-injected-air-compressor%2F[/a]

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. <br> <br>Working Principle Of CMN No Oil water injected compressor <br>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&#039;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. <br> <br>Air is sucked into the air end through the air filter, getting compressed in the air end. During compression, water in injected into air end to cool and lubricate. Water gas mixture then is separated in gas water separator and compressed air is discharged from the minimum pressure valve on the top of the gas water separator to the user. Water remains at the bottom of gas water separator, being cooled by the water cooler or air cooler, and goes to air end for compression again. <br> <br>Industry Applications of CMN non oil air compressor <br>No oil compressor finds extensive applications across various industries. In the pharmaceutical and food industries, compressed air is utilized for stirring and conveying raw pharmaceuticals or food ingredients. Compressed air is directly contacted with drugs or food, so the quality(oil content, bacterial content, dust content) is highly demanded, requiring compliance with GMP or FDA regulations. In the electronic or semiconductor industry, no oil air compressor can be used for cleaning circuit boards or conveying electronic components. Also, oil free air compressors can provide a pure air source for various precised instruments. <br> <br>Features of CMN No Oil Water Injected air compressor without oil <br>Whole machine is free of any lubricating oil, ensuring absolutely oil free compressed air supply. <br>The operating temperature of the compressor is low, typically below 45 degrees Celsius. <br>Low maintenance costs, requiring only the replacement of air and water filter. <br>Isothermal compression, high efficiency with direct coupling of the air end and motor. <br>The air end rotates at a speed of only 3000 revolutions per minute, resulting in low noise and vibration. <br> <br>Why chose CMN no oil air compressor? <br>Life time Oil free Guaranteed <br>Stability---Stably compress your air for at least 10 years <br>Easy maintenance---No wearing parts design <br>If you need water injected screw compressor air solution, feel free to send us an inquiry! <br> <br>There are many oil free screw compressor manufacturers, but we are one of the best choices for you. <br>#water#injected#compressor <br>[a]https%3A%2F%2Fwww.cmncompressor.com%2Fproducts%2Fno-oil-water-injected-screw-air-compressor.html[/a]
