Pressure belt filter
Clean processes, less downtime
In metalworking, contaminants accumulate in the coolant over time, which can affect process reliability and tool life. To maintain consistent fluid quality, the KÖBO ECO>PROCESS pressure belt filter removes fine solid particles from oils, emulsions and aqueous solutions, supporting clean processes and stable production conditions.

Overview
Pressure belt filter for coolant filtration
A pressure belt filter is an automated filtration system for cleaning coolants in metalworking. A filter belt or finer filter fleece effectively removes solid particles from the fluid after the contaminated coolant has passed through a pressure-controlled chamber. The filtered fluid is returned to the production process, while the separated solids are discharged as a dewatered filter cake.

Advantages of a pressure belt filter
High filtration performance
The pressure belt filter reliably removes even very fine particles from the coolant. This improves machining quality and extends the service life of tools and machines.
Consistent filtration quality with reduced energy consumption
Positive pressure in the upper chamber ensures uniform flow through the filter belt, increases filtration efficiency and reduces energy consumption.
No backflushing required
The pressure belt filter prevents separated solid particles from mixing back into the coolant. This saves water or coolant and energy while helping to reduce operational downtime.
Quick installation and commissioning
Pre-assembled delivery significantly reduces installation time, allowing the system to be put into operation quickly.
Modular design
The modular design allows flexible adaptation to individual production requirements and enables easy expansion of the filtration capacity.
Fully automatic self-cleaning
Integrated beater shaft, brush and rinsing systems automatically remove residues from the filter belt, reduce manual intervention and improve system availability.
Low-maintenance and durable
Robust construction and high-quality materials reduce wear, extend the service life of the system and lower long-term maintenance costs.

Overview
Design of the KÖBO ECO>PROCESS pressure belt filter
The KÖBO ECO>PROCESS pressure belt filter is a fully automatic, low-maintenance filtration system for industrial coolant treatment. It can be adapted to different operating requirements, flow rates and particle loads. The upper, pressure-controlled dirt chamber receives the contaminated coolant. A horizontal filter belt support separates the upper pressure chamber from the lower filtrate chamber.
Under positive pressure, the coolant passes through the filter medium while solid particles are retained. The cleaned coolant is collected in the lower chamber and directed to the clean tank. Pneumatically operated sealing flaps ensure reliable sealing of the filter chamber. The filtrate outlet can be positioned at the side or underneath the system. Thanks to its pre-assembled design, the pressure belt filter can be installed and commissioned with minimal on-site effort.

How the pressure belt filter works
The pressure belt filter operates fully automatically and continuously, with only brief interruptions for filter regeneration. Depending on the configuration, filtration is performed using a circulating or reversing filter belt, or filter fleece as a consumable filter medium.
1.
Filtration process: The contaminated coolant enters the upper pressure chamber. Under positive pressure, the coolant is forced through the filter medium and collected in the filtrate chamber below.
2.
Drying the filter cake: Before discharge, an airflow reduces the remaining moisture in the filter cake.
3.
Regeneration phase: A pressure measurement or preset time interval ends the filtration phase and initiates the discharge of the filter cake and the cleaning of the filter belt.
4.
Fully automatic belt cleaning: A brush or beater shaft and a belt rinsing system automatically clean the filter belt for the next filtration cycle.

Applications of the pressure belt filter
➔
Metalworking: The pressure belt filter removes solid particles from coolants, helping to extend fluid service life and maintain stable production conditions.
➔
Chip separation: Steel and aluminium chips as well as steel wool are separated from process fluids to facilitate further processing or disposal.
➔
Machining: Chips and grinding particles are separated from emulsions and oils, protecting machines, tools and downstream components.
➔
Secondary filtration: As a downstream filtration stage, the pressure belt filter increases fluid cleanliness and reduces the load on downstream filtration systems.
➔
Oil filtration: The pressure belt filter removes solid particles from oils, helping to reduce machine wear and extend oil service life.
➔
Wash water treatment: Solid particles are removed from industrial process water and wash water, supporting reuse or proper disposal.
