Application

The HydroPur hydrostatic filter is a filter fleece for cleaning cooling lubricants during material removal operations.

Use as an independent cleaning unit (e.g. when grinding) or in combination with chip conveyors (e.g. when milling, turning)
Local (for one machine tool) or central use (for several machine tools) possible

The combination of vacuum technology and filter fleece cuts operating costs through low fleece consumption and reduced loss of cooling lubricants. Thanks to a modular system, the HydroPur hydrostatic filter can be configured to individual requirements.

Properties	Benefits
Higher hydrostatic pressure compared to flat bed filters	Higher volume flow Less fleece consumption Better level of purity
Build-up of a homogeneous filter cake, especially when grinding	Good filter quality
Less residual moisture in fleece and dirt discharge	Lower loss of cooling lubricant Reduction of waste disposal costs
Plug-and-Play via universal, digital interface	Quick installation and start-up
Control with KNOLL SmartConnect	Simple operation and monitoring, also with a smartphone or tablet
Standardised design	Short delivery time Favourable price-performance ratio
Compact design	Space-saving installation

Description

Filtration process

Contaminated fluid flows through the inlet into the filter
The filter fleece retains the dirt particles as they pass through
The dirt particles form a filter cake that separates even the smallest dirt particles
The optional vacuum support favours the filtration
The clean fluid is collected in the clean tank
Low- and high-pressure pumps supply the machine tool with clean cooling lubricant as required

Regeneration process

The growing filter cake increases the flow resistance
The fluid level in the filter increases
The belt drive switches on at a defined level and transports the filter fleece onwards
The carrier belt transports a piece of clean filter fleece onto the filter surface
The level of the dirty medium decreases again
After leaving the dirty medium, the filter fleece runs across a drying section into the sludge container or into an optional take-up unit
