Coalescer Separator Filter Vessels
Precision Filtration Products supplies coalescer-separator filter vessels for separating water and solid contaminants from fuel, oil, and other compatible industrial fluids. Available in vertical and horizontal configurations.
ASME CODE COALESCER SEPARATOR FILTERS
Coalescer Separators for Water & Solids Removal
Two-stage coalescer-separator filter vessels are the primary defense against fuel contamination by water and dirt. The coalescer separator housings contain both first-stage coalescer and second-stage separator cartridges with no internal moving parts. They are designed to meet commercial and military Energy Institute (EI) test specifications.
Our two-stage coalescer separators will continuously remove solids and water contaminants from aviation fuels. Vertical and horizontal housing designs are available with a wide selection of coalescer and separator cartridges to meet specific applications. All are built to ASME Code, Section VIII, with many standard and optional accessories and connections available to facilitate piping and installation requirements.

FAQ’s
What types of contaminants do coalescer-separator vessels remove?
These vessels are designed to remove both solid particulates and free water from fuels or light oils. The coalescer stage captures solids and forms large water droplets, while the separator stage removes the coalesced water before the fuel exits the vessel.
How often should coalescer and separator elements be replaced?
Element life depends on fuel quality, solids loading, and water content. Coalescer elements typically require more frequent replacement than separator elements. Routine outlet testing and differential pressure readings are the best indicators of when a changeout is required.
Can coalescer-separator vessels handle emulsified water?
Yes, but performance depends on the fuel’s surfactant load. High surfactant levels can reduce separation efficiency, which is why clay treaters or pre-filters are often placed upstream to restore proper coalescing performance.
What information is needed to size a coalescer-separator vessel correctly?
Key information includes flow rate, fuel type, allowable water content, expected solids load, temperature, and whether the application is permanent or temporary. This determines the proper vessel diameter, element count, and flow configuration.
Are coalescer-separator vessels suitable for aviation fuel or only industrial fuels?
They are widely used for both. These vessels are standard equipment in aviation fuel handling, pipeline terminals, military operations, and industrial fuel purification systems where water removal and particulate control are critical.
