Centralised Vacuum System for CNC Woodworking
Reduce Energy Costs by 25% in Premium Cabinet Manufacturing
In the manufacture of high-end cabinetry and sliding door systems, a reliable vacuum source is not merely an accessory to CNC routing; it is fundamental to process stability and finished-product quality.
This case study demonstrates how rethinking vacuum generation can improve efficiency, reliability and long-term performance, particularly as vacuum systems are often one of the largest hidden energy consumers in CNC operations

About the Customer
A UK-based premium manufacturer specialising in bespoke cabinetry, architectural sliding doors and precision surface finishes operated a multi-CNC environment where sheet stability, machining accuracy and cycle time efficiency were critical.
As production volumes and energy costs increased, the company began reviewing how vacuum was generated and distributed across the facility. By upgrading to a centralised vacuum system for CNC woodworking, the manufacturer achieved a 25% reduction in energy consumption.

Why Vacuum is Critical in CNC Woodworking:
In CNC nesting applications such as cabinetry, sliding doors and decorative panels, vacuum is essential for maintaining material stability during machining. Consistent vacuum performance ensures:
- Stable sheet positioning during routing
- Reduced micro-movement during cutting
- Clean edge finishes
- Improved machining precision
- Consistent part quality
Most CNC vacuum systems operate between 250–350 mbar(a), where both vacuum level and airflow must be carefully balanced to maintain effective hold-down.
The Challenge: Distributed Vacuum Systems
The manufacturer, Integral Doors, previously operated four CNC routers supported by 16 BECKER VTLF vacuum pumps (up to four per machine) along with four VLR 251 claw pumps. While this configuration delivered sufficient vacuum performance, it created several inefficiencies common in multi-CNC woodworking facilities.
Each machine operated independently, resulting in:
- High installed motor capacity
- Simultaneous full-load operation
- Excessive energy consumption
- Frequent maintenance interventions
- Increased workshop heat and noise
Each CNC operated as an independent vacuum island, limiting opportunities for demand-based optimisation. As production volumes increased and energy costs continued to rise, it became clear that the existing system was no longer efficient. The company therefore sought a more energy-efficient vacuum solution for CNC woodworking, without compromising machining performance.
BECKER System Configuration:
Following a detailed site assessment and energy modelling analysis, BECKER designed and implemented a centralised vacuum system for our partner's CNC nesting applications.
The system included:
- Two high-efficiency VADS 1500 rotary screw vacuum pumps as the primary supply
- Integration of existing claw vacuum pumps into a centralised rack
- Intelligent control system for demand-based operation
- Factory-wide ring main supplying all CNC machines
- External installation in a purpose-built pump house
- Operating vacuum level of 300 mbar(a)
By consolidating vacuum generation into a single, controlled system, the manufacturer was able to move from fixed-output operation to demand-based vacuum supply.
Return On Investment:
Energy modelling confirmed that the new system could significantly reduce power consumption.
Based on:
- 25% energy reduction
- Electricity cost of £0.18 per kWh
- 6,000 operating hours per year
The project delivered a strong and clearly defined return on investment.
At the required operating vacuum level, the screw vacuum pumps delivered improved efficiency and lower shaft power demand than the previous system. For manufacturers evaluating similar upgrades, calculating energy savings in CNC vacuum systems often reveals faster payback than expected.
Operational Improvements Beyond Energy Savings:
In addition to reducing energy costs, the centralised system improved overall production performance.

Is a Centralised Vacuum System Right for Your Facility?
Centralised vacuum systems can offer major advantages for woodworking manufacturers operating multiple CNC nesting machines, high sheet throughput, decorative laminates or vinyl-wrapped components, engineered panels, or architectural sliding systems.
In these environments, stable and efficient vacuum performance is essential for maintaining consistent production.
If your operation is experiencing rising energy costs, increasing maintenance demands or inconsistent vacuum performance, it may be time to reassess your current setup. In many cases, redesigning the vacuum system — rather than replacing individual pumps — unlocks significant efficiency gains.
Expert insight: Designing for Long-Term Performance
When transitioning to a centralised vacuum system, factors such as acoustic design, installation planning, energy modelling and future scalability should be considered early in the process. Taking a holistic engineering approach ensures reliable, long-term performance — supported by BECKER as your trusted vacuum solutions partner.
“The move to a centralised vacuum system has improved stability across our CNC operations and reduced overall energy consumption. Maintenance is now simpler, and the system gives us confidence as we continue to scale production.”

Frequently Asked Questions (FAQ)
| What vacuum level is required for CNC nesting? |
|
Most CNC nesting applications operate between 250–350 mbar(a), depending on material permeability and sheet size. spoilboard condition. Achieving the correct vacuum level ensures stable material hold-down, preventing movement that can affect machining accuracy and surface quality. More porous materials may require higher airflow, while denser materials can perform effectively at lower flow rates. |
| Is a screw vacuum pump more efficient than a vane pump for woodworking? |
|
The most efficient solution depends on the specific application, operating vacuum level and production requirements. At mid-range vacuum levels (around 300 mbar), rotary screw vacuum technology (VADS 1500) can offer strong energy efficiency. However, all screw, claw and vane technologies have their advantages, and selecting the right solution requires a detailed assessment of the process. At BECKER, we take a consultative approach - recommending the most suitable technology based on your process, not a one-size-fits-all solution. |
| What are the benefits of a centralised vacuum system? |
|
Energy savings, improved reliability, lower maintenance, reduced noise, and scalability for multi-CNC facilities. |
| How can I reduce energy costs in CNC woodworking? |
|
Energy savings can be achieved by optimising vacuum generation through system design, pump selection and intelligent control. Factors such as installed motor capacity, operating hours and load conditions all influence energy consumption. Using an energy savings calculator is a practical first step in identifying potential improvements. |
