Kromschroeder GFK32R40-6 (81938200) Gasfilter

The Kromschroeder GFK32R40-6 (81938200) gas filter is a component installed in the gas supply line upstream of the gas valve. Parts of this type protect the valve, burner control, and metering components from particles, dirt, or pipe debris that could impair sealing or block gas orifices. The filter is typically placed between the main shut-off valve and the gas valve train, often directly before a multiblock or solenoid valve. Selection of a replacement gas filter depends on the connection size and thread type, the required flow capacity for the burner output, and the filtration fineness (mesh rating). For safe operation, the filter element must be cleaned or replaced at intervals specified by the burner manufacturer; a clogged filter causes pressure drop and can lead to incomplete combustion or burner lockout. When exchanging a filter of this type, ensure that the gaskets or seals are renewed and that the flow direction arrow on the housing matches the gas flow.
