Filtro per gas Kromschroeder GFK50F60-6 (81941103)

The Kromschroeder GFK50F60-6 (81941103) is a gas filter. Parts of this type are installed in the gas supply line upstream of the gas valve, burner control, and other sensitive components. They remove solid particles from the gas stream — debris, rust, or scale that can originate from the pipework or the supply — to prevent clogging of valve seats, servo regulators, and nozzles. In a typical boiler or burner system, the gas filter is the first component after the manual shut-off valve and before the gas pressure regulator or the multiblock. Such filters are selected by connection size (threaded or flanged), the housing material, the filter element mesh or porosity, and the maximum operating pressure. The flow capacity must match the burner output; an undersized filter causes pressure drop, while an oversized one may not trap fine particles reliably. The element can be washable or replaceable, and some designs include a differential pressure gauge to indicate when cleaning is due. When replacing a filter, check that the sealing gasket is in good condition and that the flow direction arrow on the housing points toward the gas valve. Also confirm that the filter rating is compatible with the gas type (natural gas, LPG, or biogas) and that the temperature and pressure ratings suit the installation.
