POOLKING's depth sand filter connected with 2" or 3" flange , it has two different sand beds . Coarser less dense sand at the bottom of the filter bed , and finer , denser particles in the top layer . The downstream filtering allows very deep and effective filtration of particles and higher filtration rates . With this combination , a depth sand filter provides many advantages over a conventional sand filter .
The advantage of a fixed nozzle bottom is that filtering takes place through the entire surface . At the backwash , the reverse circulation takes place at depth which results in a very efficient backwashing . In order for a visual inspection to take place in a very simple way , the sand filter is fitted with a sight glass in clear plexiglass . Equipped with manual venting and large manhole for easy maintenance . These filters are well suited to commercial pools or spas.
