Gas filtration

What is gas filtration?

Gas filters are used to remove (solid) particles and aerosols from a gas stream. The particles are captured in a fine filtration filter medium. By using an Interfilter Group gas filter, you can achieve a clean gas stream without contamination. All gas filters from Interfilter Group guarantee an efficiency of at least 98%.

Various types of gas filters

Here you will find our various types of gas filters which are available in different sizes and types. The gas filters are used for removing contaminants, removing mist, and separating liquids from a gas stream. The types of gas filters used for this purpose are: hot gas filters, dry gas filters, particle filters, coalescers, and separators. For more information, visit a specific product page of the gas filter or contact one of our employees.

Frequently asked questions

A gas filter is used to remove solid contaminants from a gas stream. A coalescer combines very small liquid droplets into larger droplets. A separator then removes these larger droplets from the gas stream. Which type of filter is required therefore depends on the contamination present in the gas.

A coalescer and separator are usually used together when small liquid droplets need to be removed from a gas stream. The coalescer causes small droplets to combine and become larger, but does not remove them from the gas stream itself. The separator then removes the larger droplets from the stream. If solid particles are also present, a solids removal filter can be used as an additional filtration stage.

Gas filters are used under a wide range of process conditions. The filter element, seals and housing must be suitable for the pressure and temperature at which they are used. An element that is suitable for a standard gas stream is not automatically suitable for a process with very high temperatures. Therefore, always provide the operating pressure and temperature when selecting a gas filter.

To select a suitable gas filter, information about the gas stream and the contamination that needs to be removed is required. Data such as the flow rate, operating pressure and temperature are also important. The required filtration rating, available connection and available dimensions for the housing can also play a role. Based on these data, Interfilter can determine which filter element and housing are suitable for your process.

Special hot gas filters are available for high-temperature gas streams. These filters are designed to remove solid particles from hot gas streams where standard filter materials are not suitable. The required version depends on factors including the maximum temperature, the type of gas and the contamination. Based on these process data, Interfilter can select a suitable filter.

Yes. Interfilter supplies replacement gas filters for various existing installations and brands. The range includes alternatives for GSFE, Golden Super, Parker, EFC, PALL, Consler and Dollinger. Preferably provide the current part number and process data. This allows us to determine which replacement is suitable.
