What Are Filter Discs?

A filter disc filters different fluids, especially in irrigation projects. As it prevents blockages from occurring and impurities from building up in your system, it can save you thousands in expensive repairs. In this blog, we will be outlining the advantages of filter discs, their varying types, and unique features.

Similar in appearance to a screen filter, filter discs distinguish themselves in that their filter cartridge consists of different discs stacked on top of one another, each of which is blanketed in grooves or small bumps. Each disc or ring has a hole at the center that provides a hollow cylindrical passageway for water to pass through while the disc blocks particulate matter.

Generally, the quality of filtration is determined by the size and quantity that the filter element can retain. To make identification simpler, the discs are color coded to denote the filtration level. The micron rating for a majority of filter discs range from 20 microns for a very fine filtration level and reaches up to 400 microns for a coarse level of filtration.

Some filter discs may measure filtration quality in terms of mesh size. In such cases, the size of the mesh will range from 40 microns to 600 microns, where the lower range is the coarsest and the higher range is the finest. It is also important to note that filter discs are available in different sizes with small variations being as compact as ¾’’. Filter sizes are also dependent on the application at hand, meaning that small options may be ideal for drip irrigation systems and large options are suitable for industrial applications.

Filter discs offer a myriad of benefits, some of which we will cover. First, a filter disc is relatively easy to maintain, and you will spend very little time removing or cleaning the filter disc. Second, based on the application, the filter disc does not function under very high pressure, meaning that the system may not require a power system to increase the pressure. Next, installation necessitates little to no effort due to small space requirements. Lastly, they perform optimally in a variety of projects, are flexible, and provide long service lives.

The most significant part of the filter disc is the filter segment with a fabric coat. When water flows into the disc through the inlet of the filter disc housing, it makes its way through the inner space of the filter segment, and the fabric coat traps the impurities in the water. As previously mentioned, the filter disc is equipped with a series of stacked discs that determine its filtration capabilities. The more layers, the higher the quality of filtration. Once the water passes through all the layers of the filter disc, it finally exits through the filter housing outlet.

There are a variety of filter disc types, each of which is capable of performing different functions. For example, mesh filter discs are available in flat and pleated variations and are best suited for cleaning or protecting a gas or liquid flow system. Fiber filter discs, on the other hand, are not as effective for fluids with few contaminants. Other common filter discs include powder, automatic, and manual filter versions.
