The Poly Blown Sediment Filter is extremely efficient at removing particulates such as dirt, rust, sand, scale and salt. It is a very important stage of the RO or RO/DI system as these particulates would otherwise clog up the RO Membrane quickly.
Having good water pressure is crucial for the operation of your RO or RO/DI system, we recommend changing out the sediment filter every 4-6 months, or when a 5PSI drop is observed. If your system does not have a pressure gauge, you can easily add one with our Pressure Gauge Kit.
All AquaFX RO and RO/DI systems feature Poly-Blown Sediment Filters. These filters are made of Thermally-bonded 100% Pure, FDA-grade Polypropylene. No adhesives, silicone nor lubricants! Chemical and Bacterial resistant for increased service life.
Poly-Blown Sediment Filters are made by melting down small Plastic Polypropylene beads. Once melted, the resin is blown through a very fine nozzle with hot air. The filter created for the melted resin is collected on a rotating collection tube. Heat bonds the fibers together so no adhesive is required. The collected fibers form a tube and the tube is then cut to size for use in your filter. The concept is similar to that of a cotton candy machine.
By adjusting the fiber size, the rotation speed of the collection tube and the air flow, different pore sizes are created to form different layers on the sediment filter. This gradient design allows the entire filter to be utilized; maximizing the dirt-holding capacity while minimizing the pressure drop.
Larger particles are trapped on the outside of the filter cartridge, while the smaller/finer particles are trapped closer to the core of the cartridge.
For applications with unusually high amounts of sediments in the water supply, a pleated sediment filter can be added before the RO/DI system to remove the larger sediment particles.
At AquaFX, we offer better filters, better service!
