  • Quick-release couplings for easy filter changing

Baclyser® WG

Baclyser® WG is a CE-marked medical device and has been developed specially for the sterile filtration of water in the supply line of birthing pools. It is equipped with a 0.2μm hollow fibre membrane for microfiltration ensuring bacterial retention resulting in 7 log reduction of Brevundimonas diminuta. This complies with the FDA definition of sterile filtered water. The filter thus holds back all microbes present in the water system such as Pseudomonas and Legionella bacteria.

Filtration does not alter the chemical composition of the water. Baclyser® WG supplies microbe-free water at a high flow rate allowing rapid filling of the pool. The quick-release coupling of the filter connections and the aqua stop incorporated in the filter inlet allow an easy filter change. After the end of its service life the filter can be disposed of in the appropriate way.
