Selection
Choose a low-flow or medium-flow style filter for instruments with ? female thread at the inlet; the high-flow filter is suitable for mounting into instruments with ? female thread; the ultra-low-flow filters have 1/8" connections.
In principle select finest porosity with low P; preferably P not higher than 250 to 500 mbar, and porosity not bigger than 5 ?m.

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.
