Refill Case 10 Inch Fat 4.5″ Diameter – Empty Cartridge Shell for Custom Filtration

The Refill Case 10 Inch Fat 4.5″ Diameter offers a durable, empty filter cartridge shell that can be filled with your choice of media to suit specific water‑filtration needs. Designed with a wide 4.5″ outer diameter and standard 10″ length, this cartridge gives you the flexibility to customise your system for applications from residential to light commercial.

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

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.

Technical Specifications

• Size: 10″ length, 4.5″ outer diameter (“Fat” size)
• Shell Material: Polypropylene white body for rugged service and corrosion resistance.
• Refillable: Yes—empty shell allows you to load media of your choice.
• Pre/Post Screens: Built‑in screens to prevent media loss during operation.
• Applications: Compatible with many standard 10″ “fat” housings found in water‑treatment setups.
• Colour: White body for easy visual inspection and clean installation.

Applications & Benefits

Install this refillable cartridge in your 10″ “fat” filter housing when you want full control over your filtration media. Use it in water‑bars, under‑sink systems, or UV/RO setups where custom media blends are required. Because the Refill Case 10 Inch Fat 4.5″ Diameter supports higher media volume, you benefit from enhanced service life and improved filtration performance. Plus, the ability to refill means you can tailor the media to your water quality (for example, heavy chlorine load, high iron content, or heavy aerosol sediments).

Installation & Usage Tips

• Ensure your housing accepts a 4.5″ outer diameter cartridge and is rated for your system’s flow and pressure.
• 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.
• Install the cartridge in the correct flow direction, and check the sealing O‑rings for leaks.
• Monitor flow and pressure drop; replace or refresh media when performance declines.
• Because the shell is refillable, keep a log of media changes and ensure compatibility with your water chemistry.
