Donaldson Ultrafilter Coalescing Filter Replacements

Donaldson Ultrafilter Coalescing Compressed Air Filters

ProAirSupply supplies replacement coalescing filter elements and compressed air filtration components for Donaldson Ultrafilter systems. These filters are used to remove oil aerosols, condensed water, and fine particulate contamination from industrial compressed air.

Proper coalescing filtration helps protect air dryers, pneumatic equipment, instrumentation, valves, and downstream processes while improving compressed air quality.

How Donaldson Ultrafilter Coalescing Filters Work

Coalescing filter media captures very small liquid aerosol droplets suspended in the compressed air stream. As the droplets pass through the element, they combine into larger droplets that can drain away from the air stream.

This process helps reduce compressor oil aerosol, liquid moisture, and fine particulate before compressed air reaches downstream equipment or processes.

Donaldson Ultrafilter Replacement Filter Elements

Replacement elements should be matched to the correct filter housing, filtration grade, airflow requirement, and operating conditions. Similar-looking elements may have different dimensions, seals, filtration efficiencies, or mounting configurations.

Verify the complete Donaldson Ultrafilter part number before ordering a replacement element.

Coalescing Filter Applications

• Oil aerosol removal: Helps reduce compressor lubricant carried downstream in the compressed air.
• Water aerosol removal: Helps remove fine liquid moisture from compressed air systems.
• Fine particulate filtration: Captures small solid contaminants that may pass through upstream filtration.
• Air dryer protection: Helps reduce contaminant loading on downstream refrigerated and desiccant air dryers.
• Equipment protection: Helps protect pneumatic tools, valves, controls, instrumentation, and production equipment.

Donaldson Ultrafilter Filtration Stages

Compressed air treatment systems may use multiple filtration stages to achieve the required air quality. A particulate or prefilter can be installed upstream of a finer coalescing element, with additional final filtration used where required by the application.

The correct filtration sequence depends on the equipment, contaminant load, and required compressed air quality.

Finding the Correct Donaldson Ultrafilter Filter

The most reliable way to identify the correct replacement element is by using the original Donaldson Ultrafilter part number and the filter housing model.
