Machine Tools and Metalworking
The machine tool and metalworking industries place the highest demands on precision, process reliability, and plant availability. Turning, milling, drilling, and grinding inevitably generate chips, abrasion, fine particles, and oil and emulsion mist, which directly impact the machining process and machine performance.
Filtration is a central component of production in this sector. It ensures that cooling lubricants, hydraulic oils, and process air are continuously purified of contaminants. Only with clean, conditioned media can tool wear be minimized, sensitive machine components protected, and consistent machining quality guaranteed.
At the same time, modern filter technology makes a significant contribution to the efficiency and sustainability of metalworking. The treatment and reuse of cooling lubricants reduces media consumption and operating costs, while the separation of dust and oil aerosols ensures clean, safe working environments.
Filtration is therefore far more than just a supporting function: it forms the basis for stable processes, long service life, and a high-performing, competitive machine tool industry.
Industry in focus
Clean fluids and ambient air – with energy-efficient filtration solutions in production facilities
Industry applications
Filtration solutions for media, emissions, and drive systems in machine tools
Gear oil filtration
Hydraulic drives in machine tools require clean, high-quality oil to ensure precise movements and a long service life for the components. Even the finest particles can lead to malfunctions, performance losses, or premature wear.
Pressure filters, air breathers, and duplex filters ensure the necessary oil purity on a permanent basis – even during continuous operation and under heavy loads.

Coolants filtration
Coolants cool, lubricate, and flush the machining zone and remove chips. The purity of the medium is crucial, especially for internally cooled tools and high-pressure systems.
Modern systems combine self-cleaning automatic filters with disposable depth filters to ensure reliable filtration even under extreme conditions. Dual-switch filters enable uninterrupted operation by seamlessly taking over when one filter is changed.

Industrial air pollution control
Dry machining or minimum quantity lubrication (MQL) processes—especially when machining gray cast iron—generate highly abrasive chips and a high proportion of fine dust. These particles pose a significant burden on machines and the environment.
High-performance dust extraction and dust collection systems with star-pleated filter elements and patented cleaning systems ensure effective particle separation. The gentle cleaning of the filter elements guarantees maximum service life and consistent extraction performance.

Oil aerosol separation
When cutting, grinding, or drilling oils are used in machine tools, fine oil aerosols are generated that can settle in the machine environment or be released into the exhaust air. Closed-loop oil aerosol separators enable decentralized, highly efficient separation of these emissions directly at the machine.
The purified air is returned to the production area, while the separated oils are reused in the process.
Advantages
- Clean working environment
- Protection of machinery and electronics
- Compliance with legal environmental and occupational safety regulations
- Recovery of valuable cooling lubricants
