Kromschroder Gas filter GFK65F10-6 81942190

The Kromschroder GFK65F10-6 gas filter (SKU 81942190) is a flanged unit with a nominal diameter of 65 mm, designed to be installed in the gas supply line upstream of the gas valve and burner control. It traps particulate matter and debris to protect valve seats, burner nozzles, and other sensitive components. The filter has a maximum operating pressure of 1 bar, conforms to ISO 7005 flange standards, and includes pressure test points at both inlet and outlet. Replacement is recommended when the pressure drop reaches 20 mbar. The type designation is GFK 32R40-6, and it carries article numbers 81942190 and 624.880.018.

When selecting a replacement gas filter of this type, verify the connection size (flanged or threaded), the micron rating of the filter element, and the maximum operating pressure of the system. Ensure the flange standard matches the existing piping (e.g., ISO 7005) and that the filter is compatible with the specific gas type (natural gas, LPG, or biogas). Before installation, check the condition of the housing seal and replace it if hardened or cracked. After installation, measure the pressure drop across the filter to confirm it is within the clean element value.

A clogged gas filter of this kind can cause a significantly higher pressure drop than the clean element value, reducing gas flow to the burner. This may lead to flame instability, incomplete combustion, or safety lockout. Regular inspection or use of a differential pressure gauge is recommended to detect clogging. If the pressure drop reaches the replacement threshold (e.g., 20 mbar for this type), the filter element should be replaced.
