Dixon hygiene filters for your BSCCQ inline and side-entry filter/strainer units are constructed from a variety of materials depending on size. These filters are special-order, and minimum requirements may apply; contact us for details. Use of this filter requires the use of two retaining rings, which are not included with the base unit. These filters are made from disposable process media and designed to remove finer particles from the stream. These filters can be used to filter particles down to 40 microns in size.
