Instrumentation Filters

Headline filters are one of the largest manufacturers of instrumentation and gas analysis filters in the world and have an enviable reputation within the industry.

Headline filter housings and cartridges are suited for use in a wide range of applications.

Headline filters offer many advantages over traditional filtration methods with its ability to be used in high temperature applications and chemically aggressive environments as well as for general purpose filtration.

Headline 110 & 120 series filter housings are constructed entirely from 316L stainless steel with viton seals. They are free from welds and comply with NACE MR-01-75.

(1) Above 200ºC the pressure rating is reduced, consult Headline Filters for the exact rating at any specific temperature.

(2) Maximum temperature 200ºC using standard seals. For temperatures up to 450ºC use a high temperature gasket.

(3) Replace ‘xx’ with grade required, e.g. 12-32-50C, SS-12-32-25, PT-12-32-03.


The Headline Membrane Filter consists of a highly porous hydrophobic or oleophobic PTFE membrane in a stainless steel/PTFE housing with two bypass ports and inlet and outlet ports. The ports are designed to allow for permanent pipework, thereby enabling easy maintenance of the filter membrane. Within the housing 3 angled venturies cause the gas to be rotated beneath the membrane, helping to keep the membrane clean and at the same time allowing the finer gas molecules to pass through the membrane for gas sampling and leaving the larger liquid molecules to exit through the bypass ports. Further benefits of the Headline Membrane Filter are that it is extremely inert and is recommended for most applications, the only exception being hydrofluoric acid. It is always recommended to use a coalescing pre-filter and to use the membrane filter as the last form of protection. The membrane is currently available in high flow applications.
