The Aquafilter FCCA20BB is a 20-inch Big Blue granular activated carbon (GAC) water filter cartridge designed to reduce chlorine, selected organic contaminants and unwanted tastes and odours in potable water. Its coconut-shell activated carbon media provides effective adsorption, helping improve the taste and smell of treated water.

Designed for compatible 20-inch Big Blue filter housings, the FCCA20BB is suitable for point-of-entry (POE) and other larger-capacity water filtration installations in domestic and commercial settings.

Granular activated carbon filtration

The FCCA20BB uses a blend of activated carbon media, including coconut-shell granular activated carbon, together with a polypropylene non-woven filter layer. The carbon helps reduce free chlorine and selected volatile organic compounds (VOCs), while the cartridge's construction helps retain filtration media within the cartridge.

Aquafilter's FCCA series is designed to improve water quality by reducing substances that can affect the taste and odour of drinking water.

Up-flow filtration design

The FCCA20BB uses an up-flow filtration arrangement, with water passing through the cartridge from bottom to top. This design provides contact with the granular carbon media during filtration.

The 20-inch Big Blue format offers a larger media capacity than standard 10-inch cartridges, making it suitable for systems requiring a higher-capacity carbon filter.

Suitable applications

The Aquafilter FCCA20BB can be used in compatible filtration systems for:

• Reducing chlorine in mains or treated water.

• Improving unpleasant water tastes and odours.

• Reducing selected organic compounds and VOCs.

• Domestic whole-house water filtration.

• Commercial and larger-capacity water treatment installations.

• Pre-treatment stages in multi-stage filtration systems.
