Why Correctly Sizing Pneumatic Components is Important

The most important function in the design of a pneumatic system is to correctly size the pneumatic components. Too often, components are chosen primarily because of what is readily available at the time or because the component is already currently being used throughout a facility. Improperly sourced components can result in an inefficient system leading to decreased productivity and increased cycle times, along with increased component and energy costs associated with compressed air.

One of the key factors in determining how to properly size for performance and efficiency includes Fittings & Tubing selection.

Fittings and Tubing Selection

Fittings and tubing are often the most overlooked components in the system. Many times the selection is based on what tubing size is normally used in the plant. This can lead to a poor performing system by restricting the flow or it can act as a volume chamber needing to be filled and dumped at every cycle. The length of the tubing greatly affects its flow capacity and should be taken into consideration when designing a system. Once you’ve determined the Cv required for the system, you can easily use the following charts as a general guideline in selecting the proper fittings and tubing.











Optimizing performance, reducing component costs and reduced energy costs associated with compressed air are all easily achieved if time is taken to properly size out air components within the early planning stages of your design.
