How to choose

Determine gas consumption (flow rate)

Calculate the total air consumption: You should sum the air consumption of all your pneumatic equipment (units: m³/min or L/s).
Apply the simultaneous use factor: Since your equipment will not operate at full load simultaneously, you should typically multiply the total by a factor of 0.6-0.8.
Include a margin: You should add a 10-20% margin to accommodate future expansion.

Determine work pressure

Check the maximum operating pressure requirements of your gas-using equipment.
Common pressure ratings include: 0.7 MPa, 0.8 MPa, 1.0 MPa, and 1.3 MPa.
Note: Pipelines typically cause a pressure drop of approximately 0.05-0.1 MPa. You must account for this pressure loss when selecting your system pressure.

Comparison of key performance parameters

Energy Efficiency Indicators

Specific Power (kW/(m³/min)): Users should select models with lower values for better energy efficiency; National Level 1 Energy Efficiency requires a specific power of ≤ 7.2.
Variable Frequency vs. Fixed Frequency:
  • Users experiencing large gas consumption fluctuations should choose variable frequency drives (achieving 30-40% energy savings)
  • Users with stable gas consumption should choose fixed frequency drives (reducing initial costs)

Cooling Methods

Air Cooling: Manufacturers design these for easy installation; users should select this for small and medium-sized models in moderate ambient temperatures.

Water Cooling: Engineers optimize these for superior heat dissipation and low noise; users should select this for high-power applications in high-temperature environments.
