I. Core Parameter Analysis
Air Discharge (m³/min)
Calculation should be based on the total demand of the air consuming equipment, multiplied by a 1.2 safety factor. For example, if the total air consumption of a production line is 10m³/min, it is recommended to choose a model with an exhaust capacity of 12-15m³/min.
Scenario adaptation: laboratory small equipment can choose 0.5-2m³/min oil free scroll compressor; semiconductor production line and other large displacement demand scenarios, it is recommended to choose the centrifugal compressor exhaust volume>10m³/min.
exhaust pressure (bar)
Conventional working conditions (such as food packaging, pneumatic tools) For normal working conditions (e.g. food packaging, pneumatic tools), the exhaust pressure is 6-8 bar; for high-pressure conditions (e.g. laser cutting, high-pressure cleaning), the exhaust pressure is 10-13 bar, and the high-pressure model of the
Oil Free Screw Compressor should be selected.
Power (kW) and energy efficiency ratio
Priority is given to IE4 permanent magnet motor models, for example, the energy efficiency ratio of a certain model of ZAKF reaches 4.8kW/m³/min, which is more than 20% of energy saving compared with traditional models.
Application Scenario Adaptation Strategy
Food and Pharmaceutical Industry: To meet ISO 8573-1 Class 0 oil free standard,
Water Lubricated Oil Free Compressor is recommended to avoid lubricant contamination of the gas source and comply with GMP production standard.
Electronics and semiconductor industry: Ultra-clean vacuum environment (oxygen content <1ppm) is required, oil free scroll compressor is suitable for chip manufacturing, LCD panels and other precision processes by virtue of oil free and clean characteristics.
Chemical explosion-proof field: ATEX certification is required,
Dry Screw Vacuum Pump can handle flammable and explosive gases, and the motor and electronic control system have Ex d IIC T4.
Automobile manufacturing: under continuous high load working conditions, oil free Screw Compressor has better durability, and it can satisfy the continuous gas supply demand of spraying and assembling lines.
Evaluation of Brand and Technical Strength
Certification Standards
CE/PED certification is required for the EU market (e.g., ZAKF models comply with 2014/68/EU), and ASME BPVC Section VIII Div. 1 certification is required for the North American market.
Intelligent Technology Configuration
Permanent magnet inverter models (e.g. ZAKF VSD series) can be selected for scenarios with large load fluctuations (e.g. intermittent production), with energy saving of up to 30%; with the IoT remote monitoring module, vibration and temperature can be monitored in real time (with an accuracy of ±0.1%) to provide early warning of failures.
Maintenance and cost optimization
Maintenance cycle: replace the filter element every 2000 hours for oil free scroll compressor and check the scroll disk every 5000 hours; centrifugal compressor needs overhaul by professional team every 10000 hours.
Full life cycle cost: the initial investment of oil free scroll compressor is 15% higher than the same displacement screw machine, but the IE4 motor model saves 20% electricity compared with IE2, and the difference can be recovered in 3-5 years.
