Vacuum technology
Central Vacuum Systems
Many pumps, one managed system.

How it works
Central vacuum systems combine multiple pumps, receivers, piping and controls to serve a whole plant or department instead of individual machines. They can reduce installed capacity and energy use when demand varies.
Pumps feed a receiver and distribution network. Controls stage pumps or adjust speed to hold a set-point as demand changes.
Performance range
Depends on the pump technology inside the system
Typical industry range. Exact capability is model specific, see each model’s curve.

Advantages & tradeoffs
- Redundancy
- Lower total connected load
- Heat and noise moved out of the work area
- Piping design matters
- Higher upfront engineering
- Single point of failure without redundancy
Best applications
Common in Packaging, Medical.
Maintenance
Per pump technology, plus receiver drainage, controls and leak management.
Energy characteristics
Specific-energy comparisons (kW per unit of flow at your operating point) appear here as sourced performance curves are added. Until then, compare models directly on the Performance Map.
