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%.
Noisy - affects staff working, complaints from residents
Maintenance problem---Maintenance is hard, changing oil causes environmental pollution, and efficiency drops huge with delayed maintenance
High temperature - Potential safety hazard
In the working process of high-pressure oil free screw compressors, through two-stage compression, the CMG series can provide pure oil-free compressed air of 20 to 40 bar pressure. The air enters the first-level air end through the air filter element for compression. When the pressure reaches 5 to 7 bar, it enters the water vapor separation barrel for separation. Then the compressed air enters the second stage air end for secondary compression.
At this time, the pressure in the high-pressure oil-free compressor will reach 20 to 40 bar. It is separated again through the second-stage water vapor separation barrel, passes through the post-processing equipment, and reaches the user. The motor is directly connected to the air end for transmission, with a maximum speed of 3000rpm. The speed is automatically adjusted through a frequency converter (frequency range 40% to 100%) to ensure that the gas production of the high-pressure oil-free compressor matches the actual gas consumption to achieve the purpose of reducing energy consumption.
CMN oil-free high-pressure oil free screw compressors offer a perfect solution for PET bottle blow molding, especially for beverage bottles, cosmetic containers, medicine containers, and infusion containers.
Beverage bottle/ water bottle production: generally requires 25~35 bar compressed air. Oil pollution influences the taste of beverages or water and affects consumers' health
Cosmetic container: Touch with skin directly. Oil pollution will affect skin health.
Medicine and infusion container: Strictly regulated by the FDA, the product shall be free of oil and bacteria.
For the CMG series high-pressure oil free screw compressors, all parts that come into contact with compressed air are made of food-grade 304 stainless steel, and rotors are lubricated by water to ensure the compressed air is absolutely clean and pure
No-wearing parts design: CMN high-pressure oil free screw compressors have fewer parts than traditional piston compressors, have a simple structure, and only need to replace the air filter and water filter for maintenance; the operation cost is low.
Low noise and low vibration: screw-type compression, very low noise, and small vibration.
Energy saving: Equipped with a permanent magnet variable frequency motor, and isothermal compression to realize high efficiency.
