The vacuum filter VL is a high-performance filter for the cleaning 
of cooling lubricant during material removal process, in particular 
with grinding processes. The combination of vacuum technology and 
endless belt produces a pure filter concentrate with low residule 
moisture and forms the bases for a particularly economoically efficient use. 
Filter Process: 
The contaminated fluid streams into the bottom of the sludge tank and 
rises. The vacuum pump extracts the air out of the filter chamber 
producing a vacuum there. The vacuum together with the hydrostatic 
pressure of the contaminated fluid create a high pressure difference 
at the filter surface. The fluid passes through the filter belt, which 
holds back the dirt particles in the filter chamber. A thick filter cake 
is produced here, which acts as a filter medium and holds back the smallest 
of particles. A filter pumps extracts the cleaned fluid into the clean tank.

Filter Belt Regeneration: 
The increasingly thick filter cake slows down the volume flow through the 
filter surface - the level of contaminated fluid rises. At a defined level, 
the belt drive switches on and conveys the carrier belt together with the 
filter belt a small distance forward. This allows the clean filter belt 
to reach the filter surfacem the volume flow increases and the level of 
contaminated fluid drops. After moving out of the contaminated fluid 
the endless belt runs through the following stations dry phase, scraper, back washing abd belt drying.
