Description
The Kromschroder Gas filter 81939200 is a gas filter with a nominal diameter of DN 40 and an Rp internal thread. It is designed for use with natural gas, LPG, or biogas, and is compatible with the gas composition. The filter has a maximum pressure of 4 bar and includes pressure test points at the inlet and outlet. With a clean filter pad, the maximum pressure gradient is 10 mbar.
Further details
| Differential pressure gauge port | some filters include a differential pressure gauge port for monitoring |
|---|---|
| Filter element replacement | replaceable without removing the body from the pipe |
| Function | remove solid particles and pipe debris from the gas stream |
| Installation position | upstream of the burner control train |
| Maintenance requirement | inspect and change at scheduled intervals or when noticeable pressure drop occurs |
| Pressure drop warning | noticeable pressure drop across the filter |
| Pressure gradient increase | will increase with soiling due to the gas |
Choosing and fitting
When selecting a gas filter of this type, ensure the connection size (DN) and thread type match the existing pipeline. The filter must be suitable for the specific gas type (natural gas, LPG, or biogas) and the operating pressure must not exceed the filter's maximum pressure rating. Check the flow direction marked on the housing and verify that the seal material is compatible with the gas composition.
Signs of failure
A clogged or missing gas filter can cause erratic valve operation, pressure drops, or failure of downstream components such as pressure regulators and burner nozzles. Symptoms may include reduced gas flow, unstable flame, or unexpected shutdowns. Inspect the filter element for soiling and replace it if the pressure gradient exceeds the recommended limit.
