Composed of a low-pressure stage and a high-pressure stage, the two-stage compressor is driven by a single motor. The compressor head features an integrated gearbox for variable speed operation. The first stage delivers a discharge pressure of approximately 2.2 bar, after which the compressed air passes through an intercooler into the second stage for further compression. Both the rotor surface and the inner walls of the main housing are specially coated to enhance efficiency and extend service life. The coating is thin yet hard, offering excellent corrosion resistance, heat tolerance, and long-term durability.
The rotors are all treated with special composite coating for surface treatment, which is durable and can withstand high temperatures and pressures. The unique structural design enables them to match different specifications easily. The operation and maintenance are simple. The professional shaft seal design ensures that the compressed air is absolutely oil-free.
| Pharmaceuticals, Biotechnology Compressed air usually comes into direct contact with products or packaging. Zero-grade oil-free air prevents oil contamination from directly transferring to the products. For the requirements of sterile air in the process, zero-grade oil-free air is even more indispensable. Our zero-grade compressed air technology can avoid issues related to product safety. | Food and beverage industry Oily-free compressed air, after being compressed at high temperatures, helps food and beverage manufacturers avoid the risk of contamination. During processes such as packaging, filling, and sealing, compressed air usually comes into direct contact with the products. Zero-grade oily-free air ensures high product purity, eliminates the risk of contamination of the final products, and avoids potential health hazards. |
| Chemical Industry The quality of compressed air is of paramount importance in the chemical production industry. Safety is the top priority. Issues such as safety management, equipment malfunctions, operational errors, and unknown chemical reactions can all be mitigated by using oil-free compressed air. This can help chemical producers reduce risks through their compressed air systems. | High-quality spraying industry Impure gases often result in poor coatings. High-quality spray finishes require oil-free compressed air as the first choice. Oil-free air effectively eliminates oil stains, which may hinder the adhesion of the paint and cause premature corrosion. It ensures the adhesion of the paint and prevents blistering. |
| Textile industry Jet looms require dry and oil-free air. During the production process, the fine nozzles blow the air onto the yarn bundles, creating vortices that give the yarn its shape, elasticity and resilience. The pure compressed air provided by the oil-free compressor can ensure the quality of the finished fabric. | Electric power industry Compressed air is mainly used in control instruments. The operation of thermal power generating units requires a large number of control instruments to support the operation. And the actions of these control instruments are all controlled by oil-free compressed air. Even the desulfurization of flue gas also requires oil-free compressed air. |
