The filter footprint is very small given the flow, compared to Vacuum DE or Sand Filters. These filters are designed to use Perlite, a filter media similar to DE but which does not contain crystalline silicate, the Hazardous Component of DE, making Perlite a nuisance dust only, and Perlite is lighter than DE which means it is flushable, with- out clogging drains. When the pressures in a Defender filter rises, instead of backwashing the filter it can be “Bumped”, the media shaken up, redistributed, and reused several times before being replaced. The water usage to maintain/backwash this style of filter is very low. The “Lever Bump” models are very simple and reliable to use, and custom larger models typically have these features power assisted/automated to simplify maintenance. The recommended/ideal flow rate for these filters is 1.2 usgpm/ft2, the maximum flow rate is 2.0 usgpm/ft2. These products carry NSF, UL, and CE certifications. The larger models are priced as requested. As a replacement filter the Neptune Benson Defender Regenerative Filter requires a small footprint and can be modified to fit thru doorways. This plus the additional benefits described on this page make this the ideal filter to consider when replacing or upgrading older filters. Also ask for a cost benefit information package for your pool. These filters are priced on request. Features: 1) Steel tank with Flexsol 3000 interior lining and 10 year fully rated warranty. 2) Automation – can be upgraded with a Filter Controller to Automate and monitor all of the filter operations, and provide connectivity to VFD and UV systems. 3) Vacuum transfer of media, for ease of operation and no dust. 4) Integral filter mounted lifting davit for ease of access when needed. 5) The “Bump” feature lengthens filter run times. Benefits: 1) Low filter pressures allow more water flow at less head pressure resulting in electrical energy savings. 2) Reduction of backwash waste results in corresponding savings in water and water treatment costs.
