Kromschroeder GFK15R10-6 (81935190) gas filter

Kromschroeder GFK15R10-6 (81935190) gas filter. Catalogue article 624.880.020. A gas filter of this type is installed in the gas supply line upstream of the gas valve and the burner control. Its purpose is to trap particles, pipe scale and other debris that could block the valve seats, servo regulators or burner nozzles. The filter body contains a replaceable filter element, typically a sintered metal or wire mesh cartridge. Parts of this class are selected by connection size (threaded or flanged) and by the fineness of the filter element, which is chosen to match the maximum gas flow and the sensitivity of the downstream components. Many filters in this series have a transparent or metal bowl that allows visual inspection of the element condition. When replacing a filter of this type, verify that the flow direction arrow on the body matches the gas flow, and check the seal between the bowl and the head. The element should be replaced according to the manufacturer's service interval or whenever a pressure drop across the filter is detected. Ensure that the filter is rated for the gas type (natural gas, LPG or biogas) and for the supply pressure present on site. The brand and series designations are Kromschroder GFK, and the specific article is identified by the codes 81935190 and 624.880.020.
