Triple Stage Filter Housing Systems are available as 10" or 20" sizes, both in Standard Diameter and Large Diameter (LD) sizes (formally known as Big Blue or BB). These are supplied as a complete pre-assembled kit to included Bracket, Spanner and Differential Pressure Gauges to indicate when filters need replacing.

These are often used in commercial applications or with private water supply e.g. bore holes where the water supplied may require more treatment.
