The RO-50M is a modified version of the RO-50. The difference between these two units is the RO-50M features an auto shut-off valve, as well as a larger DI resin stage.

This system comes complete with 4 stage filtration, 50gpd RO membrane, DI mixed bed resin stage, as well as all fittings. Provides water for aquariums, propagation of plants, as well as use in pharmaceuticals.

This reverse osmosis water filter, like all unpumped reverse osmosis water filters, does rely on you having a strong mains water pressure, please do not buy this item if you do not have a good water pressure.

This unit operates best as input water pressures of between 30psi (2 Bar) & 60psi (4 Bar). We would suggest that this is not suitable for use with gravity fed unpumped cold water systems (where the water is stored in the loft). Normal UK water pressure should be from around 2 bar and above. Please note all gallons are quoted by the factory in US gallons which are 3.78 litres = 1 US Gallons.

Reverse osmosis membranes are damaged by chlorine in the mains water this why it is so important to change your prefilters regularly.

There is an option to upgrade the mixed bed resin to a colour change resin. A colour change resin changes from green to yellow straw colour when the resin is worn out.

In order to look to extend the life of the reverse osmosis element we have incorporated as manual flush valve on this unit. This will allow you to open the flush tap and allow a high pressure flow of water to go across the membrane and flush away accumulated impurities.

Filter Life

Dependant upon usage of the unit the 1, 2 cartridge filters will need changing every 6 months, the RO membrane requires changing at approximately 12 months but this is dependant upon the quality of your input water. If you live in a hard water area the life of your RO will me much lass than if you live in a soft water area.

If there is an option to supply your RO Filter from a softened water supply this will extend the life of your membrane.. The DI cartridge is designed for low output pure water production All filters are in stock and can be purchased at any time. The need to change filters is dependant upon actual use and the quality of your water. To save on postage cost we strongly recommend purching a spare set at time of original purchase.
