Poolking Commercial Sand Filter From 1200~3000mm For Commercial Pools1

POOLKING ' s commercial filter was made by the latest in fiberglass winding technology . The design and the manufacturing process of the whole vessel , incorporation of non metallic fittings plus reinforced manhole openings with proprietary methods, is unique to Poolking . Poolking are the first to introduce the benefits of the new lateral system  instead of the conventional lateral system forc ommercial filters . Poolking's new lateral configuration eliminates any " dead corner " by improving water flow distribution through the filter bed , which ensures maximum performance .

Another option is the nozzle plate system which allowws the introduction of pressurized air directly into the bottom of the filter media  .Uniform introduction of air and water through the nozzple plate provides vigorous agitation and the filter media bed expansion required for an effective air/water backwash leading to reduced backwashing times and reduce volumes of water . The minimum water and energy like that save money for the swimming pool investment and operation.
