CalMax S is designed for heavy usage when the demand for filtered water is high – the ideal solution for the office, factory etc. A robust housing unit, combined with powerful Max S cartridge, guarantees the highest level of filtration efficacy. The special wound filter construction of the Max S cartridge, extensively tried and tested in industry, effectively combats problems with sediment, dirt and discolouration of water. Contaminants are trapped within the special cartridge matrix, giving maximum filtration performance. CalMax S is easy to install by connecting to an existing tap. Little maintenance is required for a continuous supply of finely filtered water.
