Automatic backwash filter – filtration down to 50 μm
HAWLE-CANFIL is a fully automatic, continuous system that works according to the principle of surface
filtration. A wedge wire screen or metal fibre fabric is used for filter candles which retain particles of
different sizes on their surfaces. After the pre-determined degree of contamination has been reached,
the filter candles are cleaned by back-washing using small amount of filtered medium, while filtration
continues during backwashing.
