Water Boiler Filter Cartridge FC02 — Up to 4000 Litres

The FC02 is a replacement water filter cartridge designed for use with a range of commercial water boilers, including Lincat EB3F, EB4F, EB6F, EB6TF, and EB3F/PB models, as well as units supplied under various trade codes including J978, J979, J980, F934, DK882, DP498, GH184, GC719, DP495, GH183, DP496, DP497, DN984, and DN986. Its purpose is straightforward: to reduce scale-forming minerals in the incoming water supply before they reach the heating element and internal components of the boiler.

In commercial kitchens and hospitality environments, water boilers are frequently exposed to hard water, which accelerates limescale build-up on heating elements and in pipework. Left unchecked, this reduces energy efficiency, extends heat-up and recovery times, and shortens the serviceable life of the boiler. A filter cartridge in good condition helps protect the unit and maintain consistent output across busy service periods.

With a treatment capacity of up to 4000 litres, the FC02 is suited to moderate-use environments such as smaller cafés, staff canteens, or office catering points. Operators in high-throughput settings — hotel dining rooms, busy café bars, or large staff facilities — may find the cartridge requires more frequent replacement to maintain effective filtration, and should factor this into their maintenance planning.

Fitting is straightforward on compatible models, and regular cartridge replacement is one of the more cost-effective ways to protect a water boiler from the long-term effects of hard water. The replacement interval will depend on local water hardness and daily usage volume, so it is worth checking water quality data for your area when planning a maintenance schedule.

If you are unsure whether this cartridge is the correct fit for your boiler model, or if you would like guidance on filtration intervals based on your usage and water hardness, the team is happy to help before you order.
