  • Small Scale Car Detailing & Window Cleaning Water Filter
  • Ideal for Use with a Pressure Washer at flow rates of up to 7.5L/Min (6L Model) or 11L/Min (9L Model)

  • Convenient & Cost Effective alternative to Reverse Osmosis & Distilled Water

Our NEW GT1-112-DI Spot Free Rinse Window Cleaning & Car Detailing Media Vessel System produces softened, de-ionised, "TDS-Free" Water (<1 Total Dissolved Solids) to remove contaminants and particles for the ultimate, shiny, scale-free spot-free rinse, reducing the need to chamois or polish surfaces, thus reducing the risk of unsightly scratches and scale build-up! This system is perfect for small-scale applications, or for use with Pressure Washers at home (especially if you have a carbon filter system installed prior, as Chlorine/Chloramine can deplete the DI resin). Ideal for use on Cars, Boats, Trucks, Vans, Utes, Motorbikes, Caravans, RVs, Prestige Vehicles (pretty much any type of vehicle you can think of), but may also be suitable for casual users such as car enthusiasts wanting to do a regular spot-free touch-free rinse of a ceramic coated/paint protected vehicle or those with many glass fixtures around the home (i.e. windows/glass pool fences). Works well with common pressure cleaner brands such as Gerni, Ryobi, and Karcher. The 9" x 17" media vessel is compact in size and stature (for easy transportation and storage), and can be used with Pressure Cleaners at flow rates of up to 7.5L/Min (6L Model) or 11L/Min (9L Model). The inlet of the system is a 1” BSP female port with garden hose adaptors, which makes hooking the system up between your tap and pressure washer super quick and easy.

*Note: Zero (0) TDS is equivalent to <1ppm TDS. As with any filter, the capacity of virgin de-ionizing resin to remove TDS from water gradually degrades over time. As the hardness of water varies depends on the water source, there is no hard and fast rule for when you should replace the DI resin. As a rule of thumb, DI resin is due for replacement when you notice spots appearing.
