Dragon-Line can work with a variety of filters, including hydrocyclones/sand separators. Choose from semi-automatic brush away and automatic filters. See below for examples.
Hydrocyclone Filters are designed to remove >90% of sand before the filter. Because of this, the filter does not have to be flushed as often. The filter is a 4″ Dual Scan-Kleen 120 Mesh screen designed to handle up to 500 GPM and has a gauge on the inlet and outlet to get a pressure differential. It can be flushed by opening a 1″ valve and turning the crank to clean the filter screen off one side at a time.
Amiad provides a selection of low-maintenance Automatic Filters that work well with Dragon-Line, such as the Sigma Pro or the Mini Sigma Pro Series.
Semi-Automatic Inline Brush Away Filters trap dirt from water as it flows through a perforated or a weave-wire stainless steel filtration element. It provides an excellent method of manually cleaning the filter screen without removing the screen itself. It is often combined with a hydrocyclone sand separator for even better filtration.
