LF 300 Series

The LF-300 has been designed with quality and reliability in mind, with genuinely unique features designed into this single stage regulator. Finite Element Analysis, combined with physical cycle tests, created an Inconel X750 diaphragm that lasts 50% longer than a typical stainless steel designs.

The metal diaphragm means that leak integrity is maintained, and that no sample media is absorbed by the sensing element — reducing purge times between sample analysis. A Brass machined Washer also ensures no torsional load is applied to the diaphragm during assembly.
