Why this water filter earns its place
The AG557 is a genuine Lincat FC04 replacement filter cartridge for FilterFlow FX series water boilers. It is not the boiler itself; it is the consumable cartridge that keeps the filtration side of the boiler doing its job, which makes it a small part with a very practical role in a tea point, cafe counter or staff refreshment area.
Its purpose is straightforward: continued filtration of particulates that can affect the taste and quality of hot drinks. In sites where tea, coffee and hot water are served constantly, that matters because the water going into the cup has a direct effect on the drink coming out. The manufacturer also states that the cartridge inhibits limescale, helping reduce the risk of equipment downtime.
Lincat lists the FC04 for the FilterFlow FX series and names compatibility with CS570, CS571, CS572, CS573, CS574 and CS575 water boilers. It is described as easy to install, WRAS approved, and compatible with all Lincat FilterFlow FX Series boilers, so it is the replacement to check when maintaining those machines rather than trying to improvise with a generic filter.
