Paper band filters are one of the simplest forms of separating particles from all types of fluids. Its cost-effective nature and design make this filter a popular choice for many industrial applications. The filtration level ranges from 15 to 100 microns, depending on the type of application and media used.
The dirty coolant liquid from machining centers is passed through a special filter paper where all the dirty particles (ferrous and non-ferrous), grinding grit, etc. are collected. When the porosity of filter paper fills up, the dirt level in the paper rises till it touches the float switch. The float switch will then start a geared motor to remove the used filter paper and produce a fresh one in its place without disrupting the filtration process.
The filter papers are available in the form of rolls. The common filter paper materials used are polypropylene and polyester, which are selected based on the type of liquid being filtered. The nylon mesh type is our latest addition, where the filter can be reused. This is mainly used in grinding operations.
