Application

KNOLL gravity belt filters PF and belt filters for cleaning cooling lubricants chip-removing working processes.

Use as stand-alone cleaning unit on machine tools or in combination with chip conveyors
Generally local use (for one machine tool)

Properties	Benefits
Good price-performance ratio	Short amortization time
Low maintenance and wear	Low operating costs
Simple layout, easy access to all components	Easy maintenance
Can be used universally for different working processes, materials, cooling lubricants, delivery rates and degrees of purity	Simple design and planning

Description

Filtration process

Contaminated liquid flows through the inlet box into the filter trough
The filter fleece holds back the contaminant particles during streaming
The contaminant particles form a filter cake, which itself separates even the smallest dirt particles
The filtered fluid collects in the filtered fluid tank

Regeneration process

The growing filter cake increases the flow resistance
The fluid level in the filter trough increases
At a defined level, the belt drive switches on (alternatively: time-controlled)
The carrier belt transports a piece of clean filter fleece to the filter surface
The fluid level sinks again
A sludge container takes up the dirty filter fleece
