1. Meet the working pressure demand: First of all, the actual working pressure demand of the air consumption end must be determined, and on this basis, the margin of 1-2bar must be increased. This is because in practice, the length of the line and the number of turning points affect the pressure loss, especially when the line is long or there are many turning points.

2. Consider system leaks: When planning the capacity of an air compressor, it is important to take into account the leaks that may occur in the compressed air system. Leaks can cause pressure drops, so choosing a slightly higher pressure will ensure that the system will maintain the required operating pressure even in the event of a leak.

3. Influence of duty cycle: The operating cycle of the compressor in the application needs to be considered, that is, the actual running time of the compressor. This will have a direct impact on the size of the compressor and the capacity requirements of the air tank. For those duty cycles with shorter run times, higher pressures may be required to ensure that sufficient compressed air is supplied during compressor shutdowns.

4. Ensure the operation efficiency of the equipment: Choosing the appropriate working pressure will help the air compressor to operate in an efficient working area, and avoid the reduction of equipment efficiency or damage to the parts due to insufficient pressure.

5. Adapt to changing working conditions: Since different working environments and conditions may require different levels of stress, choosing a slightly higher pressure provides more flexibility to adapt to changes in working conditions and fluctuations in demand.

6. Avoid energy waste: If the pressure of the selected air compressor is too low, it may not be able to meet the job requirements, which will not only lead to energy waste, but also may cause mechanical problems. Choosing a slightly higher pressure can help avoid these problems and optimize energy and machinery efficiency.

7. Enhanced safety and reliability: Choosing a slightly higher pressure provides an additional layer of safety, ensuring that the air compressor can operate stably and reliably under a wide range of operating conditions.
