Explanation of terms
What pressure do you require?
The working pressure of a screw compressor affects energy consumption. A higher working pressure results in higher energy consumption, approximately 7% per bar.
The working pressure is determined by the minimum required pressure of the various compressed air consumers. Almost every pneumatic tool operates optimally at 6.5 to 7 bar. Excessive pressure will lead to damage to the pneumatic tools.
Often, a higher working pressure is chosen for the compressor to compensate for pressure losses from couplings, filters, or a piping network (with a diameter that is too small). The pressure of the compressed air in combination with the required capacity determines the choice of compressor.
What is the compressed air consumption?
The amount of compressed air consumed per minute is an important factor in determining the compressor size. Every pneumatic tool or production site has its own compressed air consumption. Please research this thoroughly using the information available within your organization.
Determine the maximum number of users who can work with compressed air simultaneously under the most extreme conditions and add up their air consumption. The result is the required compressor capacity. Capacity is expressed in m³/min*.
When choosing compressor capacity, consider the future as well. A compressor can easily last 10 years or longer. A compressed air system often consists of multiple compressors. When expanding an existing system, a combination of small and large compressors is perfectly feasible.
* 1 m³ is equal to 1,000 liters. Example: 0.63 m³/min = 630 liters/min.
The power of the compressor
The required power of the compressor’s electric motor is a direct result of the chosen capacity (compressed air consumption) and working pressure.
All three of these units are interconnected.
If you already know the motor power your new compressor requires, you can base your choice on that. Otherwise, it follows automatically from the entered working pressure and capacity.
