Coolant belt filter systems
Automatic filtration of coolants and process fluids
Our coolant belt filter systems remove solids from coolants, metalworking fluids and other process fluids. Depending on the filtration requirements, vacuum belt filters, pressure belt filters or compact folding belt filters are used to prepare the process fluid for continued use.

Overview
Coolant belt filter systems
How belt filter systems work
Belt filter systems are automatic filtration systems used to separate solid particles from liquids. An intermittently advancing filter belt removes the captured particles from the process fluid. Depending on the system, the filter medium consists of an endless synthetic or stainless-steel mesh belt or filter fleece supplied in rolls.
The systems can be designed with a horizontal or inclined filter area. Depending on the filter type, filtration is achieved by gravity, pressure or vacuum.

Belt filter systems for different filtration requirements
KÖBO ECO>PROCESS offers three types of coolant belt filter systems for different filtration requirements: vacuum belt filters, pressure belt filters and folding belt filters. The systems differ primarily in their filtration principle, filter area, throughput capacity and field of application.

Vacuum Belt Filter
The vacuum belt filter uses vacuum to separate very fine particles from coolants and other process fluids. It is particularly suitable for processes requiring a high level of fluid cleanliness, including applications in the metalworking and automotive industries.
The filter body also accommodates and stores the system’s coolant volume, supporting the beneficial effect of longer coolant residence times. A moderate vacuum provides high filtration performance while keeping energy consumption comparatively low.

Pressure belt filter
The pressure belt filter is a high-performance filtration system for coolants and other process fluids with a high solids content. The applied pressure increases filtration performance and enables efficient throughput while maintaining a high level of fluid cleanliness.
The system is particularly suitable for demanding applications with consistently high filtration requirements.

Folding belt filter
The folding belt filter is a compact solution for lower filtration volumes. Its simple, space-saving design allows it to be integrated effectively into existing plant areas. Although the comparatively small filter area limits the throughput, it offers clear advantages when used as a secondary filter or to supply smaller machine units.
The operating principle is based on pressure filtration of the coolant, reliably separating solids from the liquid.

Benefits of coolant belt filter systems
Efficient particle removal
Belt filter systems remove solid particles from coolants and other process fluids, helping to extend the usable life of the process medium.
Reduced operating costs
Extending the service life of the process fluid can reduce the demand for fresh fluid and lower disposal costs.
Durability and reliability
Their robust construction and high-quality materials make the systems resistant to wear and support a long operating life.
Low maintenance requirements
Automated operation reduces the need for manual intervention and helps keep maintenance requirements low.
Flexible configuration
The modular design allows the filtration system to be adapted to different process requirements and integrated into the respective production environment.
Improved process stability
Automated filtration supports consistent process-fluid quality and stable production conditions.

FAQ
Frequently asked questions about coolant belt filter systems
How do bandpass filter systems work?
The liquid to be purified enters the belt filter system from the top and is distributed evenly across the entire surface of the filter medium, which consists of a special fabric or nonwoven material. The filter fabric, which separates the contaminated area from the clean area, traps contaminant particles while the liquid flows through the filter fabric into a separate tank for further use.
As soon as the filter medium is saturated with particles, the belt motor engages, transporting the contaminated filter fabric to the filter cake discharge and to the downstream automatic belt cleaning system. The separated filter cake is removed, and clean filter fabric is fed through.
For which applications are belt filter systems suitable?
Belt filter systems are used in the following industries, among others:
- Metalworking Industry: Purification of Cutting, Grinding, and Rolling Oils
- Automotive Industry: Used in machining processes such as turning, drilling, milling, grinding, honing, or washing
- Chemical Industry: Filtration of Process Fluids for the Production of Chemicals and Solvents
- Pharmaceutical Industry: Ensuring the Purity of Liquids in Pharmaceutical Manufacturing Processes
- Food Industry: Clarification of liquids in production processes, such as in beverage manufacturing
- Plastics Processing: Removal of Particles from Coolants and Lubricants in Plastics Production
- Textile Industry: Purification of Process Fluids to Improve Fabric Finishing
