Filtro de gas Kromschroeder GFK65F60-6 (81942103)

Gas filters of this type are installed upstream of the gas valve in the gas train, protecting the valve, burner components, and control accessories from particulate contamination. They trap debris carried by the gas supply that could impair valve sealing, clog burner nozzles, or foul pressure regulators. The filter element is typically a sintered metal or paper cartridge housed in a cast or drawn body, with a transparent or metal bowl for visual inspection or a differential pressure gauge connection for service monitoring. Selection of such filters is based on connection size—usually threaded Rp 1/2" to 2" or flanged—and on the required filtration grade, expressed in microns. The flow capacity must match the burner's maximum gas throughput; a filter that is too small creates excessive pressure drop, starving the burner, while an oversized unit wastes space and cost. Compatibility with the gas type—natural gas, LPG, or biogas—and with the operating pressure range is essential. When replacing a filter, check that the gasket or O-ring material suits the gas and temperature, verify the flow direction arrow on the body, and ensure the bowl can be drained or the element accessed without disassembling the entire train.
