The drive rotor is driven by the motor, while the driven rotor is synchronized via a gear transmission. The rotors do not come into contact with each other; there is a gap between them. Compressor oil is used in this design to lubricate the gear transmission and bearings, and is prevented from entering the compression chamber by a mechanical seal on the main unit shaft.\r\n<h2>Main components, advantages<\/h2>\r\n<ul>\r\n \t<li>oil-free twin-screw unit, compact with a long service life;<\/li>\r\n \t<li>energy-efficient electric motor, brushless, with frequency control, increased efficiency;<\/li>\r\n \t<li>protective coupling, needed to protect the screw pair from overloads;<\/li>\r\n \t<li>frequency converter, smoothly regulating speed, ensuring fast response;<\/li>\r\n \t<li>cooling and filtration system for lowering the temperature of gas and oil and effectively removing impurities, dust, and moisture from the gas environment;<\/li>\r\n \t<li>programmable logic controller with an extended range of performance adjustment, the ability to connect to a cloud monitoring system;<\/li>\r\n \t<li>oil supply and filtration unit, in which the pump ensures a stable oil supply, and a dual-line dirt-trapping filter switches lines without stopping the compressor;<\/li>\r\n \t<li>separator, for two-stage separation and subsequent drying with minimal pressure loss.<\/li>\r\n<\/ul>\r\n\r\n<h2>\u0412\u043e\u043f\u0440\u043e\u0441\u044b, \u043e\u0442\u0432\u0435\u0442\u044b<\/h2>\r\n<ul>\r\n \t<li>Which compressor should you choose, oil-lubricated or oil-free?<\/li>\r\n<\/ul>\r\nOil-lubricated compressor units are more suitable for high-performance production facilities that do not require a clean air environment.\r\n\r\nOil-free compressors are in demand in industries (medical, pharmaceutical, food) where absolutely clean air without oil impurities is required.\r\n<ul>\r\n \t<li>What are the advantages of using oil-free compressors?<\/li>\r\n<\/ul>\r\nAdvantages of oil-free units:\r\n<ul>\r\n \t<li>providing absolutely clean air, free of oil impurities;<\/li>\r\n \t<li>reduction in operating costs for frequent maintenance, filtration costs, and oil replacement;<\/li>\r\n \t<li>use in industries where air purity is paramount;<\/li>\r\n \t<li>compensation for the relatively high initial cost through subsequent long-term savings;<\/li>\r\n \t<li>exclusion of waste oil disposal.<\/li>\r\n \t<li>What is the service life of an oil-free compressor?<\/li>\r\n<\/ul>\r\nThe unit can operate for 10 to 15 years depending on the intensity of use, compliance with operating regulations, design features, and timely maintenance.\r\n<ul>\r\n \t<li>\u0418\u0441\u043f\u043e\u043b\u044c\u0437\u0443\u0435\u0442\u0441\u044f \u043b\u0438 \u0432\u0438\u043d\u0442\u043e\u0432\u043e\u0439 \u043a\u043e\u043c\u043f\u0440\u0435\u0441\u0441\u043e\u0440 \u0431\u0435\u0437 \u0440\u0435\u0441\u0438\u0432\u0435\u0440\u0430?<\/li>\r\n<\/ul>\r\nSuitable for continuous consumption and stable supply.
