That always depends on the specific application.
Experience shows that the motto "more is better" is often applied. Unfortunately, this is not always a good idea from an energetic point of view.
For example: Parts are cleaned using a standard blow gun. If the pressure is increased from 4 to 6 bar, the compressed air consumption increases proportionally to the pressure. This means that the consumption (cost) increases by 50 bar because the pressure is increased by 50 bar (from 4 to 6 bar).
Simplified example: If a compressed air gun consumes 200 l/min at 4 bar, it would consume approximately 300 l/min at 6 bar.
If the amount of moving air needs to be increased at the same pressure, some of our products are helpful.
Small detail, big impact: By using a different nozzle, in this example, with otherwise unchanged parameters, up to >700l/min can be moved instead of 200l/min by utilizing the Venturi effect.
