Description
Puretec IMB+ Series is an innovative filter with a patented system of cleaning composed of two different actions: brushing of the filtering cartridge and high speed discharge. This method allows an efficient and thorough cleaning both of the filtering cartridge and the filter bowl. The cleaning is started by rotating clockwise the upper grey knob: this movement activates, at each click, the brushing system and the opening of the discharge valve which creates a high-speed tangential flow that removes impurities accumulated in the filter bowl.
