Adsorption Dryer Compact UDD
Ultrafilter offers 7 different standard compact adsorption dryers. In addition, our adsorption dryer meets all maintenance requirements that guarantee maximum performance and ease of use.
The extremely compact design, which can be installed both vertically and horizontally, is very space-saving and contains a complete filtration package with both pre- and post-filter and condensate sinks.
Why drying compressed air?
Compressed air is used in almost all areas of industrial production as a source of energy or processing. Compressed air must be dry, oil-free and clean to prevent downtime and loss in production quality. The atmospheric air that is sucked in contains harmful substances, dirt, particles and moisture in the form of water vapors, which censor in compressed air pipes and can lead to significant damage (corrosion, freezing, etc.).
Which model should you use? Read the table at the bottom of the page or find further info in the data sheet, which you will find on the product page.
How does the UDD work?
Two vessels connected in parallel are required for the continuous operation of drying via the adsorption process. Each vessel is filled with desiccants which act as the drying medium. AFE desiccant dryers use high performance molecular sieve which have a long service life at high input temperatures, resulting in very low pressure dew points.

Ultrafilter UDD – Quality and reliability
Compressed air is a commonly used power source. Over the years it became a crucial part of a wide range in industrial processes. However, compressed air after compression is not clean and contains impurities like water, oil, dirt, wear particles and so on. This mixture creates a form of condensate which damages downstream equipment like air tools, pneumatic cylinders and other pneumatic equipments. It also causes high product rejects, high maintenance and costly air leaks in compressed air systems.
The use of highly efficient compressed air filters and condensate drains will remove a lot of these impurities and can eliminate most of the problems downstream. For many applications this is not enough. These applications need an even higher level of compressed air quality. AFE’s UDD desiccant dryers will provide this level of air quality at the point where the quality is needed without investing a large amount in centralized purification systems which are often not needed because only certain areas of the production process need that high quality air.
The UDD series of compact desiccant air dryers offers users the air quality at the point where it is needed. Utilizing a reliable technology, the UDD dryers provide the security to run the process without interruption and to have safe and reliable operations of downstream machines and air tools. This series comes with installed pre- and afterfilter, desiccant fill and a reliable PCB controller with indication lights to monitor the operation. The PCB controller is ready build in and only has to be connected to an electrical power source and compressed air inlet/outlet. Optionally available is a dryer run/stop dry contact as well as a load control system for energy savings. This series of compact desiccant air dryers will meet the requirements of ISO 8573.1 Class 1.2.1 as a standard. Higher quality classes based on request are available.
