Our range of filters and filter dryers offer a complete solution to every instrument gas supply or liquid filtering problem and includes particulate filter dryers through to coalescers.

Our instrument filters are used extensively for removing contaminates that include Sulphur, Mercury, particulates, aerosols and water from the gas before it is used for such duties as gas supply to pneumatic instruments, valve actuators or analysers.

In addition, similar filters with a change of filtering element are used for contaminate removal in liquids for applications such as odourant injection.

Care should be exercised to ensure that the medium being filtered does not have an overload of impurities as they could quickly contaminate the filter element and inhibit flow. In cases such as these staged filtering may be a solution.

Also, the selection of a filter body that has capacity to drop out and store the contaminates before the gas passes through the filtering elements is a wise choice, provided of course the drain is operated periodically.

In cases where there is a high level of liquids, pre-filtering with a coalescing filter element should be considered.

Care should be exercised in the selection of a filter for filtering analyser gas. Filtering could remove some of the heavy ends that should form part of the analysis.
