Reduce Cost, Protect, and Maintain System Performance.
Two-in-one filtration with supreme energy savings
Atlas Copco’s UD+ oil coalescing filters efficiently reduce oil aerosol, wet dust and water drops in your compressed air stream to protect your investment, equipment and processes. The UD+, combines two filtration steps (DD+ and PD+) into one, a unique technology to meet the high-quality requirements of diverse applications and provide ultimate energy savings.
UD+ Filters are suitable for flow rates up to 1165 cfm @ 100 psi and are available with threaded connections ranging from 3/8” to 3”.

Features and Benefits
Suitable for Most Industries
The UD+ filter is designed for most industries with a compressed air system*.
*Flow rates up to 1165 cfm @ 100 psi and are available with threaded connections ranging from 3/8” to 3”.
Protection, No Matter the Manufacturer
The UD+ filter is compatible with all compressor and dryer manufacturers. Its purpose is to protect the dryer and downstream equipment and tools from moisture, oil vapors, and other contaminants that may come out of the compressor and dryer.

|Filter rating||Type||Liquid ppm (part per million)||Particles micron||ISO class|
|A||Compressor – UD+||Air purity class ISO 8573-1:2010 [1:-:2]|
|B||Compressor – UD+ – Refrigerant dryer||Air purity class ISO 8573-1:2010 [1:4:2]*|
|C||Compressor – UD+ – Refrigerant dryer – QDT – DDp+||Air purity class ISO 8573-1:2010 [2:4:1]|
|D||Compressor – UD+ – Desiccant dryer – DDp+||Air purity class ISO 8573-1:2010 [2:2:2]|
|E||Compressor – UD+ – Desiccant dryer – QDT – DDp+ – PDp+||Air purity class ISO 8573-1:2010 [1:2:1]|
* Particle class 1 is reached directly after UD+. As downstream piping & vessels can add particles, it is advised to install particle filters DDp+ and PDp+ just before the application to reach particle class 1 at point of use.
The compressor should be equipped with a liquid water separation system such as an after cooler including a drain or a water separator (WSD). Always install a water separator in front of a coalescence filter. In case of critical applications, install extra air treatment products at point of use for the removal of pipeline contamination and condensation.
