Configure high-vacuum extraction to meet your specific needs
The right configuration determines whether a high-vacuum system achieves the desired suction capacity, ease of use, and expandability in actual operation. In addition to the extraction unit, the piping network, hoses, connections, filters, capture elements, and control system must be coordinated with one another. Even small changes to cross-sections or line lengths can affect pressure loss.
Here’s what you should look for when making your selection
✔ Number of extraction points in use simultaneously
✔ Required vacuum pressure and air flow rate
✔ Hose and pipe diameters
✔ Filtration and discharge system
✔ Dust type and potential ATEX requirements
✔ Control, operation, and expandability
Consider the system rather than individual components
For high-vacuum extraction systems, a holistic approach is particularly important. The capture element, together with the hoses and piping network, creates a defined resistance. The exhaust unit must be able to overcome this resistance while maintaining the required air flow. Therefore, an option is only practical if it matches the actual operating point of the entire system.
Typical configuration ranges
✔ Number and location of extraction points
✔ Hose lengths and hose reels
✔ Filter equipment and cleaning
✔ Collection containers and discharge
✔ Electrical control and automatic start
✔ Conductive design for special applications
Selection Guide
| Planning Point | Impact | Practice |
|---|---|---|
| Hose length | Pressure loss | Keep the translation as brief as possible while maintaining clarity |
| Cross-section | Flow velocity | Tailored to the system and application |
| Outlets | Total demand | Take simultaneity into account |
| Type of dust | Filters/Safety | Clarify material properties in advance |
FAQ
Can a high-vacuum extraction system be expanded later?
Generally speaking, yes, provided that the power reserve, piping network, and control system allow for the additional withdrawal points.
Why is the hose diameter so important?
It influences flow velocity and pressure drop, and thus the actual operating point.
Does ATEX always have to be taken into account?
Only if the specific application is relevant to explosion protection. The substance, process, and risk assessment are decisive.
Can any of the options be combined as desired?
No. Components must be technically and flow-wise compatible with one another.
Configuration Guidance
For more complex high-vacuum systems, it is worthwhile to consider the extraction unit, piping network, hoses, and collection points together. This allows the configuration to be tailored to the actual application.
