The coolant fluid with iron dust particles falling by gravity to the inlet of the separator from the precision machine tools such as grinders, milling machines, automates etc. The coolant with iron impurities come in to contact with magnetic drum and extracts all iron particles.

The magnetic drum is kept clean at all times by a scrapper blade along the circumference.

A rubber roller squeezes the sludge gathered to ensure that no coolant is wasted.
