Description
The Kromschroder gas filter 81937200 is designed for the purification of combustible gases and air, ensuring stable operation of gas-consuming equipment. It has a nominal diameter of DN 25 mm and features an Rp internal thread. The maximum operating pressure is 4 bar. The pressure drop across a clean filter pad should not exceed 10 mbar, and replacement is required when the pressure drop reaches 20 mbar.
Further details
| Application | effective purification of combustible gases and air |
|---|---|
| Pressure Drop Operation | contaminants gradually accumulate on the filter element, leading to an increase in pressure drop |
| Pressure Test Points | pressure test point at the inlet and outlet |
| Typical uses | various gas systems, including industrial installations, heating systems |
Choosing and fitting
Parts of this type are selected by nominal diameter (DN) and thread type, which must match the existing piping. The filter is installed with an Rp internal thread connection. Before ordering, verify the DN and thread type against the equipment specifications. The maximum permissible pressure of the system must not exceed the filter's rated pressure.
Signs of failure
As the filter element accumulates contaminants, the pressure drop across it increases. When the pressure drop reaches the replacement threshold, typically indicated by a pressure gauge or differential pressure switch, the filter element must be replaced. Failure to do so may allow impurities to pass through, potentially causing malfunctions or damage to downstream equipment.
