The Aquafilter FCCBKDF-L is a 20-inch granular activated carbon (GAC) water filter cartridge combining coconut shell activated carbon with KDF-55® filtration media. Designed for compatible slimline 20-inch filter housings, it helps reduce chlorine, selected organic compounds and heavy metals while improving the taste and odour of drinking water.

The combination of activated carbon and KDF media provides multi-media filtration for domestic and commercial water treatment systems. Its extended 20-inch design offers a greater filtration media capacity than standard 10-inch cartridges.

Coconut shell activated carbon and KDF-55® media

The FCCBKDF-L combines two complementary filtration technologies:

• Coconut shell granular activated carbon (GAC): Helps reduce free chlorine, organic compounds and substances that can cause unpleasant tastes and odours.

• KDF-55® media: Uses an oxidation-reduction process to help reduce chlorine, iron, hydrogen sulphide and selected heavy metals. It also has bacteriostatic properties that help inhibit microbial growth within the filtration media.

• Polypropylene filter layers: Help retain the filtration media inside the cartridge and prevent it from escaping into the filtered water.

Both the coconut shell GAC and KDF-55® media are identified by Aquafilter as NSF-approved media.

Up-flow filtration design

The FCCBKDF-L uses an up-flow filtration arrangement, with water passing through the cartridge from bottom to top. This provides extended contact time with the activated carbon and KDF media, supporting the adsorption and treatment process.

The combination of media is designed to help improve water quality while retaining naturally occurring minerals such as calcium and magnesium.

Suitable applications

The Aquafilter FCCBKDF-L can be used in compatible water filtration systems for:

• Reducing chlorine and improving water taste and odour.

• Reducing selected volatile organic compounds (VOCs).

• Helping reduce selected heavy metals, including lead, arsenic, cadmium and mercury.

• Reducing iron compounds and hydrogen sulphide.

• Supporting filtration in domestic and commercial water treatment systems.

• Point-of-use (POU) and point-of-entry (POE) filtration installations.

Installation and replacement

Install the Aquafilter FCCBKDF-L in a compatible 20-inch slimline filter housing. Check the housing dimensions before ordering, as this cartridge is designed for a standard 2.5-inch diameter housing and is not suitable for 20-inch Big Blue housings.

For improved cartridge service life, Aquafilter recommends installing a suitable sediment pre-filter upstream of the FCCBKDF-L.

Flush the cartridge in accordance with the manufacturer's installation instructions before use. Replace it regularly to maintain filtration performance. Actual service life depends on incoming water quality, chlorine concentration, flow rate and total water consumption.

Important: This cartridge is intended for cold potable water filtration. Do not use it with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the filtration system.
