UD+ SERIES

Two-in-one oil coalescing filters with supreme energy savings

UD+ 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+ oil coalescing filters

Reduce energy costs by 40% with the UD+ two-in-one oil coalescing filtration solution. Best-in-class air purity. Protect your investment, equipment and processes.

Next generation of filtration solutions

Atlas Copco has launched the UD+ coalescing filters, which combine two filtration processes in one product. The UD+ is unique in the market and offers energy savings, efficiency gains and reliably clean compressed air.

40% energy savings

A 40% lower pressure drop than the conventional line filter combination results in 40% higher energy efficiency thanks to our unique Nautilus filter technology.

Small footprint

The two-in-one filtration concept reduces installation space and complexity, making these filters particularly suitable for applications where space is at a premium.

Save money

Install the UD+ to enjoy significant cost savings compared to conventional filters.

Pure air

Air purity is equal to that obtained using two conventional filters in line, thanks to the design of UD+ filters and the media used.

No risk of cracks in filter media

Nautilus filter technology runs no risk of cracks in the filter media because the filter media are wrapped around the filter.

SFA silicone-free filters

Our SFA filters provide exceptional air purity for applications where silicone-free air is required, such as painting and automotive. Protect your end-products.

Silicone-free removal of oil aerosol, dust and oil vapor.

Guaranteed silicone-free

We produce our SFA filter housings and elements in a clean room environment and clean and test them according to certified procedures.

Maximum contaminant removal

Our SFA filter ensures maximum removal of dry and wet dust, particulates, oil aerosol and water droplets through its high-efficiency glass fiber and fleece media.

Energy savings

The design and media used for our compressed air filters minimize reduction in pressure.

High performance

High-quality materials such as stainless steel cores, double O-rings, epoxy sealed caps and anti-corrosive coated filter housings are selected to ensure high performance and reliability.

Easy maintenance

Push-on elements and external ribs on the threaded housing make filter maintenance easier.

SFA ensures superb air purity

Our high-quality silicone-free SFA filters safeguard your instruments and end products by efficiently preventing dry and wet dust, particulates, oil aerosol, oil vapour and water drops from entering your compressed air system. The SFA is certified by the Fraunhofer Institute as guaranteed silicone-free.

Why choose SFA silicone-free filters?

Although our standard compressed air filters thoroughly clean air, they still have potential to release silicone into the air stream from lubricants, components and processes used during manufacturing. That’s why it is crucial to install SFA silicone-free filters to prevent major problems from occurring such as paint defects like craters and blisters, or even poor paint adhesion.

 Examples of typical installations

A SOLUTION FOR EVERY APPLICATION
At different points of use, different compressed air purities might be needed, depending on the application.
The various air purity classes are provided in the table below, which clearly shows the various Atlas Copco filters and dryers that meet all the different classes.

Importance of filter

Get clean compressed air by using the right compressed air filters. Protect your pneumatic equipment.

Compressed air filters protect your equipment from dust, dirt, oil and water. Dust will wear down your equipment (like the air motor in grinders, pneumatic actuators and it can make pneumatic control valves get stuck.Especially when the dirt and dust is combined with oil (which is often the case with compressors), a sticky mess can form inside valves, motors and other compressed air equipment.

To protect your equipment, you need to install some compressed air filters.

Which ones? Find out below…

There are many different kinds of filters, and I have often seen people using the wrong one.

I have seen many ‘compressed air filter mistakes’ for that matter, like: wrong filters installed, too small filters installed, filters installed in the wrong place.

People also tend to forget about their filters… while the compressor gets its service every year, people seem to think that their filters will last a lifetime!

That’s not true of course… and it will cost you money!

Filter build-up

Look at the picture below what a typical filter looks like. The workings are quite simple: air enters on one side and goes through the filter element, where all dust, water or oil is collected. The clean air then leaves the filter housing on the other side.

Take Atlas copco filter as example,

Filter types

So you need a compressed air filter, but are overwhelmed by all the different types, sizes and specifications. Don’t worry! Let me help you..There are:

Particulate filters

Particulate compressed air filters are used to remove dust and particles from the air.

Coalescing filters

Coalescing filters are used to capture oil and/or moisture that is suspended in the compressed air in very tiny droplets.

Activated carbon filters

Activated carbon filters will remove odors and vapors. They are used in factories where food is produced or for breathing-air for example.

Filter elements

As you can see above, the compressed air filter usually is made up of two main parts: the housing and the filter element.

The filter element itself is the part that is doing the job: filtering your compressed air.

In some cases, the filter housing is doing an important job too: it’s often used to separate dust or water/oil droplets by cyclone action. What does it mean? The housing is designed in such a way that the compressed air moves around in it like in a tornado. All the solid particles and droplets will get smashed into the walls of the housing, while the rest of the air moves to the filter element.

You can buy the filter elements separately from the housing, so you can change them for new ones every year or so.
