Oil-free screw air compressor compresses air through two-stage screw rotors, and removes water from the compressed air through a water-gas separator. At the same time, because there is no oil injection cooling, it is generally equipped with a pre-cooler, an intercooler, and an aftercooler to cool the compressed air to reach the required exhaust temperature. The shaft of the rotor is sealed with excellent performance to prevent lubricating oil from leaking into the compressed air, so as to achieve true oil-free.
The turbine rotor rotates in the order of Figure 1→2→3→4, and the air is sucked into the space between the turbine stator and the turbine rotor. The volume of the crescent-shaped (point-symmetrical) compression chamber gradually decreases, and the compressed air is discharged from the exhaust port in the center.
Oil-free scroll air compressor produces high-quality pure compressed air without oil, and is widely used in food and beverage, biology, electronic semiconductor, scientific laboratory, chemical industry and precision spraying and other fields.
Quiet
The scroll compressor is silent and has little vibration, providing a comfortable working space. There is no need to worry about affecting the environment even if it is operated at night.
Saving
Multiple air compressors are built into one chassis, and multi-level control is used to achieve operation and energy saving. Multi-level control is used to freely operate according to the number of units according to the amount of air used, thereby eliminating unnecessary operation and achieving energy saving.
Cleanse
No oil is needed for lubrication, and the exhaust air is of course clean. Due to the standard optional rust-proof air tank, the drainage is also clean. Therefore, a clean environment can be maintained at all times.
Small
The air machine has a smart design and a small and simple box, which greatly reduces the installation space. It can be easily moved after installing casters.
