IN-LINE Filter<br /><H2>High Flow Serie M-423</H2>


Inherent to its construction, a thermal mass flow meter or controller for gases is sensitive to contamination. To increase the MTBF (Mean Time Between Failure) it is important to make sure that the gas entering the instrument is clean. The IN-LINE Filter Assembly, screwed into the inlet of the instrument, provides this service. It contains a 316L sintered metal filter cartridge that is suitable for general purpose filtration and can be cleaned with a suitable solvent. If the gas contains a large particulate content, we advise the use of a pre-filter.



This High Flow filter has a ½” female thread at the inlet and a ½” male tread on the outlet. The M-423 series has a porosity (µm) of 2, 5, 10, 20 or 40 μm, depending on the model. The pressure rating for this model is 200 bar. The ΔP across the IN-LINE filter can be calculated with the help of our online calculation tool FLUIDAT on the Net.
