Reverse Osmosis

Pack of 4 replacement filter foams for our 10" Reverse Osmosis resin holder.

These replacement foams can prevent the need to purchase a complete resin holder if replacement sponges are required.

Finest Filters 1/4" Reverse Osmosis tubing is available in a range of 4 colours (White, Black, Blue and Red). Typically using different coloured tubing allows for easy distinguishing of product and waste water lines in a RO unit setup. Please select the colour and length required from the drop down menu when ordering.

The Finest-Filters 4 stage RO unit with booster pump is ideal for ultra pure water production in a range of applications, and especially in situations where the water pressure is too low for effective water production rate from an un-pumped system. This is a very advanced RO unit, with a built in booster pump, automatic membrane back flush, pressure gauge, high pressure and low pressure switch.

The 300cc automatic flush valve is a replacement reverse osmosis spare part. It can be used in your unit to replace a combined manual flush and waste restrictor valve, or a current automatic flush valve.

This is a complete replacement flush valve flow restrictor assembly for use with any RO unit using standard ¼” pipe. This assembly is installed on the waste water line on the RO unit and allows the membrane to be backflushed to prolong its life.

The flow restrictor is available as either 300cc, 400cc, 550cc or 800cc. Please see our recommendation for which restrictor to use depending on the size of the membrane in your system.

Our replacement flow restrictors are suitable for use with any reverse osmosis system using ¼” push fit pipe.

The flow restrictor is available as either 300cc, 400cc, 550cc or 800cc. Please see our recommendation for which restrictor to use depending on the size of the membrane in your system.

The E-Chen self-regulating booster pumps are a newer model pump which will automatically stabilise the outlet pressure at 70psi when the inlet pressure is between 10-40psi. The consistent output pressure gives the advantage of prolonged RO membrane life.

We have these pumps available in 5 different models – 50gpd, 75gpd, 100gpd, 200gpd and 400gpd. Please select the model required from the drop down menu when ordering.

Pack of 20 x replacement 1/4" locking collet clips. These can be used with all 1/4" RO pipe fittings. Using these locking clips will prevent the pipe from accidentally being removed by mistake during use. A locking collet clip should be used on every fitting. Safety first!

Ista Auto Top Off Valve acts as a ballcock device that cuts the water flow off when the water in a container fills to a point that the float valve is raised.

These are incredibly handy with auto top off units (ATO’s) and when producing purified water such as Reverse Osmosis (RO).  

The fitting these come with is a ¼” John Guest (push fit) connection which easily connects the standard ¼” RO / High Pressure tubing.

The Ista Float Valve can be installed via a drilled hole in the container or via the hang-on bracket supplied. The float valves themselves are adjustable making them adaptable for most applications.
