In this system the filtration is produced by the retention of the particles in the channels originated by the superposition of parallel rings set. The Lama parallel disk are designed to have a large free surface passage, to favor a gradual filtration, effective and with minimal pressure drop. The disk filtration is advisable for any type of water which has a concentration of solids in suspension lower than 200 parts as million (<200ppm). Lama disk filters come in three different types of cleaning systems: automatic, semiautomatic and manuals. Plus three types of materials: plastic, carbon steel and stainless steel.
