View specification How cleaning works Upstream equipment protection Capture visible particles before they reach your softener The 40-micron mesh provides a first barrier against larger suspended particles carried by the mains supply. Installed before a compatible water softener or other treatment system, it helps prevent coarse debris from reaching the downstream equipment. 40-micron stainless-steel mesh screen Silver-coated filtration mesh Built-in pressure gauge Brass head with union-nut connections For treated municipal mains water 4040-micron meshCaptures larger suspended particles ↻Washable screenCleaned without removing the cartridge ◷Pressure gaugeIncluded for supply-pressure visibility ¾Two connection sizes3/4-inch and 1-inch unions supplied Understand its purpose A pre-filter—not a water softener or drinking-water purifier The KF-B protects downstream equipment by screening larger particles.

Kinetico does not publish it as a fine drinking-water purifier or chemical-contaminant filter. Does it soften water or remove limescale?No. The KF-B is a mechanical pre-filter. It does not remove hardness minerals or replace a water softener. Can it be installed before a Kinetico water softener?Yes, that is a typical purpose for a mains pre-filter: intercepting coarse material before downstream treatment equipment. The installer must still confirm compatibility, sizing and the correct plumbing arrangement. Does the filter cartridge need regular replacement?The stainless-steel mesh is washable and intended for reuse. Kinetico lists a genuine replacement mesh screen, reference 723723, for situations where replacement becomes necessary. What connection sizes are included?The KF-B is supplied with both 3/4-inch and 1-inch union-nut fittings. Kinetico publishes a flow of 3 m³/h with the 3/4-inch union and 4 m³/h with the 1-inch union. What pressure range does it require?The published pressure range is 1–10 bar. The installer should measure the actual supply and ensure every downstream component is also suitable for the operating pressure. Is the automatic washing kit included?No. Kinetico lists the automatic washing kit as an optional accessory under reference 723719. The standard KF-B is described as semi-automatic. Is the supplied PDF an installation manual?No. It is a technical and commercial data sheet. It confirms the product specification but does not provide a complete property-specific installation schematic. Premium product support Need to confirm the connection size or flow?
