Oil coalescence filters with patented Nautilus technology

Compressor element lubrication and your compressor installation itself can release oil aerosols and wet dust in your air system. DD+, PD+ and UD+ filters efficiently remove these contaminants to protect your equipment and your processes. These innovative filtration solutions are engineered to cost-effectively provide the best air purity and meet today’s increasingly stringent quality requirements.

Your benefits:

Maximum oil aerosol, wet dust and water droplet filtration and drainage – Highefficiency glass fiber Nautilus technology ensures a low-pressure drop.
Patented drainage technology – A coarse 3D-structured layer/barrier provides efficient oil drainage and prevents the re-entry of oil droplets into the air stream.
Minimal operating costs – Optimal design and filter technology allow for low pressure losses.
Cost-saving maintenance – Ribbed housing ensures easy removal of the filter bowl. The push-in element and drain connection were designed for effortless replacement. The service indicator shows (preventive) maintenance alerts.

UD+ 2-in-1 concept saves money and space

The UD+ combines two filtration steps (DD+ and PD+) into one, a unique technology to meet the quality requirements of diverse applications and offer superior energy savings. The UD+ filter provides the same air purity as a DD+-PD+ filter train with a lower pressure drop.

Save up to 50% in space: The 2-in-1 concept is ideal for applications where space is at a premium, reducing your environmental footprint, system complexity, and installation space.
Save money: Install UD+ filters to enjoy significant installation and maintenance (cost) savings compared to conventional filters.

Advanced filtration technology

Untreated compressed air can be contaminated by dust, water and oil. This makes filtration a crucial component of your air system. Atlas Copco has developed filtration solutions that protect your air-powered tools, your processes, and your final products. Our extensive
offer includes different filter types and a range of purity grades to meet your specific requirements.

Atlas Copco filters remove the smallest contaminants, including sand, salt and sugar grains; black carbon; rust; cement and paint particles; asbestos; and bacteria and viruses.

Filtration technology matters if you need constant air quality with low maintenance requirements. Over the years, Atlas Copco has innovated filter types, design, processes and media to give you best-in-class performance, reliability and lifetime.

Options

External wiring kit for smart indicator (alarm/power supply).
Interconnection kit.
Wall mounting kit.
EWD including connection kit.

Service indicator

To ensure constant air quality, the service indicator
allows for an easy check of the filter’s running hours,
differential pressure, and maintenance status. It can
even send a remote alert.

Element top cap

The top cap guides the air flow optimally into the
cartridge and to the outlet to reduce pressure drop and
Filtration technologies the overall energy use of the filter

Anodized aluminum housing with powder coating to maximize corrosion protection

Element bottom cap (UD+, PD+ & DD+)

A patented drainage system facilitates the removal of oil from the filter
element, eliminating the “wet band” at the bottom of the element that
can compromise filter performance and lifetime.

Strong and durable stainless-steel cylinders

The inPASS™ bypass.

Until now, servicing a filter involved shutting down the entire compressed air system or installing 3-valve bypasses around every filter. The inPASS™ re-directs the air through the filter head during maintenance, allowing for safe filter cartridge replacement without interruption of the airflow. This means there is no need to install extra piping around the filters or halt production maintenance. As a result, the inPASS™ saves customers on both installation and operational costs by allowing quick, seamless service.
