Kromschroder Gas filter GFK100F60-6 81944103

Kromschroder Gas filter GFK100F60-6 81944103 is a gas filter with a nominal diameter of 100 mm, designed for installation in gas supply lines upstream of gas valves and pressure regulators. It operates at a maximum pressure of 6 bar and features flanged connections to ISO 7005. The filter has pressure test points at both inlet and outlet, and includes a replaceable filter element. A flow direction arrow is cast into the body for correct installation.

When selecting a gas filter of this type, ensure the connection size and flange standard match the existing piping. The filter must be installed with the flow direction arrow pointing in the direction of gas flow. The filter element should be replaced according to the manufacturer's datasheet, and the gasket or o-ring between the bowl and head should be inspected for compression set during replacement.

A clogged or missing gas filter can cause erratic gas pressure, valve leakage, or burner ignition failure. If the filter is undersized or blocked, it may restrict flow and cause a pressure drop that prevents the gas pressure switch from closing, leading to burner lockout. Check the filter for blockage and replace the element if the pressure gradient exceeds 20 mbar.
