FILTERS

In order to ensure optimum reliability of safety shut off valves and other operating conditions it is often considered necessary to install filters in the gas pipeline to an appliance.

Most burner standards require a minimum of a fine strainer installed in the pipeline; this strainer is often an integral part of a solenoid or safety shut off valve.

The strainers normally must be capable of removing particles down to 0.5mm in size.
In applications wher it is thought necessary for process or safety reasons to have superior cleanliness of the gas it is necessary to install a seperate gas filter.

Gas filters are fitted with synthetic, washable filtering elements that can be removed quite easily for maintenance.

Filter elements usually filter the gas supply down to 50 microns, although special elements capable of filtering to 10 or 20 microns can be supplied.

When installing gas filters the pressure drop caused by the filter should always be considered.

For more information regarding the design, structure and application of Gas Filters consult the Technical (controls) section of this web-site.
