Most advanced heating systems use water for heat transmission. This water may also transport unwanted substances such as lime, calcium, magnesium, oxide, carbonates as well as larger particles such as welding or soldering residue, metal chips and dirt. These substances may cause malfunctions in fittings and control units. A compact flow filter (particle separator) removes these particles from the water. The particles settle in the collection chamber of the filter and can be flushed out via a valve with small amounts of water. Clean water supports trouble-free operation of systems and reduces the fuel and maintenance costs.
Clean system components have better thermal conduction, they provide for faster heating up and thus contribute to reduced fuel consumption and emissions.
The combined air/flow filter was developed for heating systems which are subject to problems caused by oxygen or other gases. The vent valve automatically removes the gases.
