As shown in the picture the controller unit comes with 3/4" plastic pre-filter (mesh 120 - 130 micron) for a better pre-filter protection and longer lifetime. Tip: if you stop using the dual chamber filter for a long time we suggest: a) make a deep backwash to avoid the sand to compact b) empty the filter from the remaining water using the two plugs below, c) remove the batteries from the controller unit to avoid rusting.

WHEN YOU NEED SAND MEDIA FILTERS:
L'AGREN sand media filters ensure very small particles filtering, like microorganisms and organic materials, that can cause irrigation system malfunctioning.
Thanks to their wide filtration area, dual chamber sand media filters are tipically installed if you have water with algae, micro-algae and organic material.
GALVANIZED STEEL FILTERS PROS:
Unlike the other filters that are just painted, L'AGREN dual chamber sand media filters are fully built in galvanized steel. This allow you to have definitely better reliability and a much longer lasting!
