Select Carefully Before Purchasing: When choosing an oil-free air compressor, two parameters must be met: exhaust volume m3/min and exhaust pressure Mpa.

Displacement: Consider factors such as air volume, the capacity of the storage tank, usage cycles, future expansion plans, and management losses. Generally, it's advisable to have a capacity around 20% more than the actual usage.

Exhaust Pressure: The actual operating pressure of the gas source equipment should be used as a reference, while taking into account pipeline losses and pressure drops caused by the purification system.
