Strong permanent magnetic tubes are fixed onto a framework. When anything containing iron/steel substances passes through the framework, the iron/steel substances will attach themselves onto the wall of the tubes. As a result, your equipment and facilities will be safe and sound, and your products will be safe for consumption.Model magnetic filters may apply in medicines, sanitation, textile, machinery and foodstuffs. The filer will attract iron/steel substances away from liquids, from among grains or powders.Size and length of the magnetic tubes, and shape of the framework will vary at your request.
