Aquarium Tank Reverse Osmosis Water Filters - Replacement Reverse Osmosis RODI Water Filter Packs To Suit Our Pro-5-Dj Models

Standard volume pre-filters can used for up to +/- 10,000 litres of RO DI water produced and the high volume Matrikx CTO filter will be able to produce +/- 30,000 litres [based on typical town water and includes waste water].

Membrane flow is rated in GPD [gallons per day] at 55psi so on average membranes produce at the following flow rates: 50GPD = 8 Litres Per Hour, 75GPD = 12LPH, 100GPD = 18LPH, 150GPD = 22LPH, 180GPD = 28LPH.

The Pentek 100GPD TLC membrane is a new generation membrane that has a higher rejection rate [98%] versus standard TFC membranes [96%] and the Pentek TLC membrane can deal with feed water TDS levels up to 4x what standard membranes can and you can download the Pentek TLC performance data sheet here.

Our resin is the highest food grade mixed bed deionising resin and is supplied loose so you can refill your existing refillable in filter cartridge or in a refillable filter cartridge [let us know if you want a white or clear cartridge or we'll dispatch according to stock levels].

All of the parts that come into contact with the water in our systems are manufactured from BPA free food grade plastics. All of the filters and parts that we source are of the highest quality and meet the required quality standards.
