Basic introduction to oil-free screw compressors

Oil-free screw compressors are divided into oil-free single screw compressors and oil-free twin screw compressors, and Mr. B. Zimmern of France in 1969 from the invention of the first oil-free screw compressor with high sealing efficiency means the birth of oil-free water-lubricated screw compressor technology. As soon as this advanced technology was discovered, it was immediately characterized as military technology by developed Western countries, and the technological blockade of developing countries was carried out for a long time. And then it is widely used in military manufacturing and ship support. The carrier-based military oil-free water-lubricated screw compressors of the United States, Britain, Germany, France and other countries have been using this technology, which makes B.zimmern's oil-free screw compressor technology develop rapidly and maturely.
