Ko te whakauru i to maatau reera rewharewha FLUID-SYSTEM, te otinga tino pai ki te pupuri i te pāmahana tino pai me te kounga o te wai o to ara iahiko waipēhi. Kei te mohiotia ano ko te reera whakawhiti, i hangaia tenei taputapu nui ki te whakaheke i te hinu wera ki te whakamatao i roto i te tuku hydrostatic, me te whakarite kia mau tonu te pāmahana, ka mau tonu te kounga o te wai.
