Frotec RO-3012-300 is a Domestic Reverse Osmosis Membrane that will provide 300 US Gallons per day, 47 Litres per hour optimum output. It is an Ultra Low Pressure Domestic Reverse Osmosis Membrane that can be used in most types of RO filters.

The Frotec membrane has a 50Psi output, which is the same pressure as most homes. This means you can expect to achieve a much higher RO water output than most other membranes that need a pressure of 60-70Psi, making them less suitable to the average home.

Other Reverse Osmosis membranes are difficult to remove from their housing, with pliers or grips need to be struggled with to break the seal. The Frotec membrane has a hexagonal thread on the end, so you simply insert an Allen key, turn, and remove the membrane. On top of this, the American Membrane technology means a 20% increased water output at lower water pressures.

Operating conditions:

  • Elements contain preservative solution, therefore the permeate from the first hour of operation should be discarded, to flush the protective solution in the elements.
  • Keep elements moist at all times after initial wetting

Elements should be immersed in a protective solution during storage, shipping or system shutdowns to prevent biological growth and frost damage.

If the operating conditions are not followed appropriately , we can not honor the warranty of the element as you will be unnecessarily reducing the life of the filter.
