Compressed air contaminated by dust, water and oil needs to be properly treated to protect your system and your end product. Atlas Copco has developed various top-quality oil-coalescing filters that ensure your operation runs smoothly, that the service life of your equipment is maximized and that your end products meet even the most stringent quality standards.
If you are unsure, and only know that you have to protect your system from dust, then you need to find out your air quality requirements. For some applications, such as inflating tires, some contaminants in the compressed air do not pose any problems. Others, such as applications in cleanroom environments, require the highest air purity. Knowing your air quality requirements and which standards to comply with will help you select the right air filter, which could lower your investment costs and ensure that you get the most out of your compressed air system. If you are not sure which ISO standard applies to your operation or which type of contaminant you have to protect your system from, you can contact Atlas Copco.
The lubrication of the compressor element or the compressor installation itself can produce oil aerosols, wet dust and water drops that could harm the entire air system. Atlas Copco’s DD+ and PD+ filters that use the oil coalescence filtration process to efficiently reduce these contaminants and ensure that your system runs more smoothly and efficiently. These high-performance, oil-coalescing filters are engineered to cost-effectively provide top air purity at a low pressure drop. Thanks to their high-efficiency glass-fiber technology and a coarse 3D-structured layer/barrier, the DD+/PD+ series allows you to meet increasingly stringent air quality demands. Their stainless-steel cores, epoxy-sealed caps and anti-corrosive coated filter housing make the filters especially reliable.
The UD+ series combines two filtration steps (DD+ and PD+) into a single unique technology that allows you to meet the high quality requirements of various applications while providing ultimate energy savings. However, they do not just save you money, but also space by eliminating the need for a second filter. At the same time, these two-in-one coalescent filters protect your equipment and processes by efficiently reducing oil aerosol, wet dust and water droplets in your compressed air stream. The UD+ series ensures a lower pressure drop than a conventional filter combination, which results in energy savings. Thanks to the thick filter package, these filters also provide an air purity equal to that obtained by using two separate filters in a row. With a patented drainage technology, the UD+ series prevents oil droplets from re-entering the air stream.

For filtering out dust (as well as other contaminants), Atlas Copco also offers the high-pressure H series of filters and its silicone-free SFA series.
DD+/PD+ and UD+ oil-coalescing filters use the wrapped technology that is especially effective for wet particles. The wrapped filtration media offer durability in wet and oil-contaminated environments. The patented Nautilus technology of the coalescing filter series combines multiple wrapped layers to ensure constant air quality in the harshest conditions.
In addition to outstanding oil coalescence filters, you also get the revolutionary built-in bypass that allows you to service your filter without disrupting the air flow. To you that means big investment savings by eliminating the need to install an expensive external piping bypass, lower operating and energy costs as well as reduced maintenance times.
To ensure constant air quality, the service indicator allows for an easy check of the filter’s running hours, differential pressure, and the maintenance status. It can even send a remote alert for your peace of mind.
Atlas Copco’s dedicated filtration team is always looking for ways to give you a competitive edge in your compressed air system. Our new generation of oil coalescence filter series feature several innovations that make your filtration system more efficient and its operation easier. Here are just three examples of how this oil-coalescing technology works.
