Today, we will start with the basics: capacity and pressure.
Pressure and flow rate are the two main specifications to consider when purchasing an air compressor;
-Pressure is expressed in bars or PSI (pounds per square inch).
The flow rate is expressed in CFM (cubic feet per minute), liters per second, or cubic meters per hour per minute.
Remember: Pressure refers to 'strength', and capacity refers to 'capacity'. one
What is the difference between a small compressor and a large compressor? The difference lies not in pressure, but in capacity.
How much pressure do I need?
The design working pressure of most compressed air equipment is about 7 to 10 bar. Therefore, most people only need a compressor with a maximum pressure of 10 bar. But in some applications, higher pressure is required, such as 15 or 30 bar. Sometimes even pressures of up to 200 to 300 bar or higher are required (such as scuba diving and paintball shooting).
How much pressure do you need?
Check the tool or machine you are using, which should indicate the minimum pressure required. However, to ensure safety, please refer to the specifications or consult the manufacturer.
What size/flow rate (CFM/m "* min) compressor do I need?
Flow rate refers to the amount of air that a compressor can pump out, measured in CFM (cubic feet per minute).
How much capacity do you need?
Add up all the pneumatic tools and mechanical equipment you have.
This is the maximum capacity required for your device in total.
