product name: zw series oil-free lubricating compressor
zw (3 ～ 10m3) series oil-free lubricating compressor is a product produced by the ministry of machinery industry in our company, and also one of the leading products produced by our factory. the series of products include zw-3 / 7, zw-3 / 10, zw-6 / 7, zw-6 / 10, zw-10 / 7, zw-10 / 10 type six basic products and a variety of types for users selected variants. the zw (3 ～ 10m3) series oil-free lubricating compressors are vertical double-cylinder water-cooled piston type, which are not oil-lubricated in the working cylinder, and are single-acting or double-acting two-stage compression type compressors. composed of compressor main engine, intercooler, inter-separator, after-cooler, after-separator, gas storage tank and control system, it is directly driven by electric motor. this series of compressors are widely used in chemical, petroleum, pharmaceutical, food, textile, environmental protection, power station, electronic component and instrument manufacturing, scientific research and other departments to transport pure gas or as equipment to automatically control the gas source. according to user needs, it can also be equipped with a corresponding gas drying and purification device.
