RATEC central vacuum systems, also known as central dust extraction systems or centralised dust collectors, serve many extraction points at once from a single plant, from machines to whole production lines. A pipe network links every dust source to the central unit, which delivers constant suction and filtration and is controlled from one place. We design every system around your operation and build it at our own plant in St. Veit an der Glan, Austria.

How central vacuum systems work
Instead of placing a separate extraction unit at every machine, a central vacuum system works with one shared central unit. From there, a pipe network runs to all extraction points in production halls, workshops or along production lines. The dust is captured right at the source, carried away through the pipes and separated in stages in the central unit. The cleaned air leaves the system via the fan.
To make sure every extraction point receives the suction it needs, suction manifolds distribute the airflow evenly. Points that are not in use are closed by butterfly valves, and sniffle valves keep the suction constant and reduce energy consumption.
Filter stages as required
The system shown in the pictures is just one example from a customer project. Every RATEC central vacuum system is built to the requirements of the respective customer.
| Stage | Component | Loading |
|---|---|---|
| Pre-separation | pre-separators or cyclone filters | catch coarse and medium-sized particles |
| Main filtration | cartridge filters | separate dry dust, fumes and fine dust |
| Ultra-fine filtration | High-Efficiency Particulate Air (HEPA) / Ultra-Low Penetration Air (ULPA) Filters | retain the finest particles and aerosols |
Your benefits
- Several extraction points at once: one system for the whole operation.
- Consistently high performance: constant suction and filtration efficiency.
- Central control and monitoring: easy maintenance in one place.
- Lower operating costs: energy-efficient design, low-maintenance construction.
- Robust and durable: built for continuous industrial use.
Key technical data
| Feature | Central Vacuum Systems |
|---|---|
| Application | production halls, workshops, production lines, machines, workstations |
| Construction | central unit with filtration and control, pipe network to the extraction points |
| Filtration stages | pre-separator, cartridge filter, HEPA filter, freely combinable |
| Control | central control and monitoring |
| Air volumes, number of extraction points, dimensions | designed individually to your requirements |
What matters in the design
- Extraction points: number, location and how many are used at the same time.
- Dust: type, quantity, particle size, combustible or hazardous fractions.
- Building: pipe routing, space for the central unit, discharge or return of the cleaned air.
- Safety: occupational health and safety, fire and explosion protection.
Everything from a single source
From initial consultation through planning, technical design and manufacturing to installation and commissioning: RATEC handles the entire process. It always starts with a careful analysis of your operational conditions. You can find out more about our approach under Extraction systems. We manufacture in our own plant in Carinthia, certified to ISO 9001, EN 1090-1 and ISO 3834-2.
