Pure air for clean water
When ventilating water chambers, contamination enters the drinking water through air exchange. For this reason, the line must be fitted with a suitable filter. The air is either filtered through polypropylene or a combination of polypropylene and activated carbon. The activated carbon layer even helps to absorb odorants.
Safety with a pre-set differential pressure
Operating the system results in underpressure or overpressure in the reservoir chamber due to filter contamination. Considerable forces act on the reservoir doors due to the fluctuations in pressure caused by contaminated filters. These forces pose a high safety risk to those entering the reservoir chamber. If a pre-set differential pressure is exceeded, a signal is output via potential-free contacts. The online differential pressure display makes this risk a thing of the past.
