4. The fourth step is to determine the compressor flow you need. This is generally determined by the flow rate. It is generally identified by CFH, or NM3/HR, SM3/HR. It is necessary to be clear that some customers are accustomed to press M3/. HR to identify, NM3 is different from M3, NM3/HR=intake pressure*M3/HR


5. Does the compressor work indoors or outdoors? What is the ambient temperature? Is there cooling water?


6. What is the local three-phase voltage frequency? For example, 380V 50HZ/3 phase, or 460V60HZ/3 phase


7. The load of the compressor is intended to work 8 hours a day, or 15 hours a day, or 24 hours?


8. Are there any other special requirements, such as whether PLC control, whether the various signals of the compressor need to be transmitted to the central control room, our standard control method is traditional switch instrument control, without PLC control

    Q13.How to choose an oil-free gas compressor suitable for your own working conditions
    1. First determine your working gas medium. If it is a single component, please let us know the purity of the gas, and whether there is water vapor and hydrogen sulfide. If there is any serious impact on the subsequent stable operation of the compressor, if it is Mixed gas, please tell us the composition of each gas 2. The second step is to determine the inlet pressure. Generally, the inlet pressure is PSIG, BARG, Mpa. Please indicate whether it is gauge or absolute pressure. Absolute pressure = gauge pressure +1 bar. If the inlet pressure is a range, Please indicate the range of fluctuation 3. The third step is to determine the pressure of use. Considering the pressure drop of the pipeline, the discharge pressure of the general compressor is slightly larger than the pressure you need. For example, if you use 100 kg of pressure, the compressor discharge pressure is 105 kg. 4. The fourth step is to determine the compressor flow you need. This is generally determined by the flow rate. It is generally identified by CFH, or NM3/HR, SM3/HR. It is necessary to be clear that some customers are accustomed to press M3/. HR to identify, NM3 is different from M3, NM3/HR=intake pressure*M3/HR 5. Does the compressor work indoors or outdoors? What is the ambient temperature? Is there cooling water? 6. What is the local three-phase voltage frequency? For example, 380V 50HZ/3 phase, or 460V60HZ/3 phase 7. The load of the compressor is intended to work 8 hours a day, or 15 hours a day, or 24 hours? 8.
