Kromschroder Gas filter GFK50F60-6 81941103

The Kromschroder GFK50F60-6 gas filter (SKU 81941103) is designed for combustible gases and air. It has a nominal diameter of DN 50 and flanges to ISO 7005. The maximum pressure is 6 bar, and the pressure drop across a clean filter pad should not exceed 10 mbar. It includes pressure test points at the inlet and outlet. The filter element should be replaced when the pressure drop reaches 20 mbar.

When selecting a gas filter of this type, ensure the connection size (flanged or threaded), flange standard, maximum operating pressure, and filter element porosity match the system requirements. The filter must be installed upstream of sensitive components like gas valves and regulators, with the flow direction arrow pointing toward the gas valve. Check that the filter rating is compatible with the gas type and that the pressure and temperature ratings suit the installation.

As contaminants accumulate, the pressure drop across the filter increases. If the pressure drop reaches the replacement threshold (e.g., 20 mbar for this type), the filter element must be replaced to prevent impurities from passing through. Symptoms of a clogged filter include reduced gas flow, pressure fluctuations, or improper burner operation. Regularly check the pressure drop using the test points to determine when cleaning or replacement is needed.
