PENTAIR's PRF-RO, the replacement to the Merlin RO or alternative to the Modular PRO system, has been designed to meet the requirements of light commercial applications without any reduction in performance. Benefiting from a smaller size and footprint to comparable systems, the PRF-RO has the added advantage of being able to operate off mains pressure. The complete system comes with all componentry,as shown, including a high capacity Fibredyne carbon pre-filter and two membranes which locate into the unique manifold with three colour coded push-fit connections for simple installation.
