Kromschroder Gas filter GFK80F60-6 81943103

Kromschroder Gas filter GFK80F60-6 81943103 is a gas filter with a nominal diameter of 80 mm, designed for filtration of fuel gas and combustion air in gas-consuming appliances. It has a maximum pressure of 6 bar and features pressure test points at the inlet and outlet. The filter pad has a standard separation rate of 50 μm, and the pressure gradient over a clean pad must not exceed 10 mbar. The filter is flanged according to ISO 7005.

When selecting a replacement gas filter of this type, ensure the nominal diameter (DN) matches the pipe size, and the flange standard (e.g., ISO 7005) is compatible with existing connections. Verify the maximum allowable pressure (Pu) of the filter is at least the system's operating pressure. Check that the filter has pressure test points at inlet and outlet if required for monitoring. Installation should follow manufacturer guidelines, ensuring proper sealing and orientation.

Gas filters of this kind typically fail due to clogging from dirt and debris. Symptoms include an increased pressure drop across the filter, which may lead to reduced gas flow and poor burner performance. If the pressure gradient exceeds 20 mbar, the filter pad must be replaced to prevent dust from being forced through. Regular inspection of the pressure differential is recommended to detect clogging early.
