Why Choose the Refill Case 10 Inch Fat 4.5″ Diameter?

n

This cartridge shell stands out because it supports custom filter media combinations—such as activated carbon, KDF, resin, or Siliphos—which makes it extremely adaptable. Additionally, the wider “fat” 4.5″ diameter gives more media capacity than standard slim cartridges, so you get longer life or higher flow before replacing them. Moreover, because the shell is refillable, you save on costs and reduce waste from disposable cartridges.

Applications & Benefits

Install this refillable cartridge in your 10″ “fat” filter housing when you want full control over your filtration media.

Installation & Usage Tips

n

n
• Ensure your housing accepts a 4.5″ outer diameter cartridge and is rated for your system’s flow and pressure.

n

• Load your chosen media into the empty shell according to manufacturer guidelines—e.g., granular activated carbon followed by KDF, or Siliphos for scale inhibition.

n

• Install the cartridge in the correct flow direction, and check the sealing O‑rings for leaks.

n

• Monitor flow and pressure drop; replace or refresh media when performance declines.

n

• Because the shell is refillable, keep a log of media changes and ensure compatibility with your water chemistry.
