Hilco seal gas filters are used to filter contaminants out of seal gas (also known as buffer gas) used in critical rotating machinery applications. These filters provide a continuous clean, dry gas and comply with international pressure vessel and design codes such as API 692.
In addition to replacement elements where Hilco filters are specified by the equipment manufacturer, Hilco can also provide direct replacement filters for most industrial seal gas applications, including systems that were built with Indufil brand filters. The table below shows some of the most common seal gas service filters. If your application is not listed, please complete the form so we can assist with your application.
