WATEX CMA8 MultiMix Water Filter
The WATEX CMA8 MultiMix is a high-performance multi-purpose water treatment filter designed for household use, capable of not only softening water but also removing organics, iron and ammonium.
The filter system consists of a filter column, control valve and salt tank. Inside the column is a blend of cation and anion ion-exchange resins which reduce hardness, organic matter, ammonium and filter out iron (if under 3 mg/L).
Automatic backwash is driven by the built-in flow-meter in the control valve (Clack WS1CI) that initiates regeneration based on water consumption — helping to save salt and water.
Although salt tablets are used for media regeneration, the treated water is fully suitable for drinking and domestic use.
Key Features:
-
Multi-purpose filter: reduces hardness, organics, iron and ammonium.
-
Built-in automatic control: Clack WS1CI valve + flow meter for efficient regeneration.
-
Suitable for household installations: requires a minimum inlet pressure (~2.5 bar) and standard 1″ connections.
-
Durable design: filter column with quality ion exchange resins and automatic back-wash functionality.
-
Recommended pre-filtration: installing a mechanical filter upstream helps extend media life.
Recommended Use:
The WATEX CMA8 MultiMix is ideal for homes, cottages, guesthouses or any residential installation where water quality issues include hardness, iron, ammonium or organic contamination. Installation should be in a dry and stable environment with access to salt regeneration and drainage.
Installation & Maintenance Tips:
-
Ensure inlet pressure between ~2-6 bar and install shut-off valve before and after filter.
-
Use a pre-filter if water contains heavy sediments.
-
Regularly check salt tank and refill with NaCl tablets for media regeneration.
-
Monitor flow meter and regeneration cycles to ensure optimal performance.
