Dryer Technology
Donaldson manufactures a complete line of refrigerated compressed air dryers, adsorption and membrane dryers to meet your specific air quality requirements and system solutions. The modularly designed processing ranges offer individual customer solutions, and therefore guarantee the highest efficiency.

Compressed Air Filters
With over 30 years of compressed air purification experience behind us, Donaldson Ultrafilter has developed an extensive line of air filtration products with a range of efficiencies and optional features to cost-effectively meet any need. Our prefilters and afterfilters can be custom-configured to suit the requirements of your specific application.

Oil/Water Separators
Compressor condensate typically contains as much as 5% oil, making it too harmful to the environment to be discharged without purification. Donaldson Ultrafilter oil/water separators process condensate to a residual oil content as low as 5 ppm, allowing the processed water to be discharged into most municipal waste water treatment systems.

Condensate Drains
Donaldson offers reliable, future orientated products for economic and environmental oriented draining and purification of condensate. Condensate purification saves disposal costs. According to your filtration solutions requirement you can choose from level-controlled condensate drains, oil/water separators for stable and non-stable solutions or complete systems for condensate treatment.

On-Compressor Filtration
Development and customised design of air/oil filtration systems improves compressor performance. A new laboratory helps us to continually improve our technology.
