<p>A skimmer box (10) forms a central housing for the components of a filtration system (20). A weir door (12) is present at an opening (14) to a body of water (2) in a pool (4) and a strainer basket (16) is positioned to provide the primary coarse straining of the water as it enters a main chamber (32). Below the strainer basket (16) is a cartridge filler (20) which is positioned such that the water must pass through the cartridge filter (20) to a central chamber (34), before passing through outlets (36a-c). A pump (50) is positioned below the filter medium (22) and forms an integral part of the lower part (24) of the slammer box chamber (30) and draws water through the strainer basket 16 and filter (20) under vacuum. As water passes through the pump (50), the lowest portion of the skimmer box (24) is under positive pressure. The number of outlets (36a-c), their diameter and the short distances the water is required to travel from the filter (20) before re-entering the pool, minimizes the pressure and friction losses.</p> |
