Finerfilters 4 Stage Dental Reverse Osmosis System with Diaphragm Booster Pump (75 GPD)
This unit will work as a direct flow system however we also have pressurised storage tanks available to purchase seperately.
It is recommended that a storage tank is installed to maintain the supply of purified water for surgeries with quick turnaround times or larger client bases. A tank would also be useful incase of an emergency such as a water outage, or continuing to use the deionised water whilst changing the filters.
This system produces up to 379 litres per day of purified water and comes complete with:
- Installation Manual.
- Stainless steel mounting bracket.
- All pipes, pre-filters, post filters, and fittings required for installation.
- Diaphragm Booster Pump with high and low pressure switches.
The membrane/s can last between 1 and 2 years dependent on water hardness.
Filters to be replaced every six months.
DI Resin to be replaced when the TDS starts to increase.
This system requires a minimum incoming / mains water pressure of 29 PSI (2 BAR) to work.
This pressure is required to operate the booster pump, do not install with lower pressures as this may damage the pump.
The outgoing water pressure from the booster pump can be adjusted. The ideal pressure required to push water through the membrane depends upon several factors such as incoming water TDS and temperature but around 60 PSI (4 BAR) is acceptable.
Reverse Osmosis Systems waste water to make water, this is normal and is how all RO systems operate.
This is due to how the membrane rejects the impure water, which goes to the drain, to produce the pure water. This process should be done at a high pressure as the water is being forced through microscopic holes which catch contaminants.
The system works optimally at 80-90 PSI (5.5 - 6 bar), and to get to the quoted output, we’d recommend running the system on or around this pressure.
This allows the system to reduce the waste water to pure water ratio and work quicker at producing pure water.
|The 4 stages of filtration are;
||5µm (micron) sediment filter made of 100% pure Polypropylene fibres. Removes suspended solids such as dirt, sediment, sand and rust.
||5µm (micron) Carbon Block filter. Composed of high performance activated coconut carbon. Removes Trihalomethanes, Pesticides and Volatile Organic Chemicals (VOCs).
||High rejection TFC (thin film composite) reverse osmosis membrane. This membrane removes contaminants present in water down to 0.0001µm Including, up to 99% of dissolved Salts, Lead, Copper, Barium, Bacterial by-products, Oestrogen and Silica and more.
||Refillable inline cartridge pre-filled with DI Resin. This cartridge, when used after RO process, uses a catalytic ion exchange process to remove water of non-essential, charged ions. This further reduces the TDS and creates highly purified water that is suitable for use in medical and laboratory use.
