Filtration technologies Choose the best filtration technology for your application to improve your air system performance:	Anodized aluminum housing with powder coating to maximize corrosion protection	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.
Wet particles: wrapped media Wrapped media are known for their durability in wet and oil-contaminated environments. Our patented Nautilus technology combines multiple wrapped layers to offer constant air quality at the lowest pressure drop, even in the harshest working conditions. • Solid particles: pleated media Pleating is the optimal technology for capturing dry particulates in compressed air. Pleated media have a large surface area and therefore ensure a longer filter service lifetime and lower pressure drop. • Oil vapors: macro-structured activated carbon Macro-structured activated carbon has a larger surface compared to the typical carbon filter media, giving it a superior adsorption capacity and a steady performance over a longer time. • Water: cyclone The use of centrifugal forces secures a proper separation of liquid water droplets in the air flow.	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   Differently colored end caps to easily recognize the filtration grade   Easy-service float drain Our non-stick float drain automatically expels all captured oil and water. To save you time and money, our drains can easily be serviced without removing the filter bowl. The threaded drain connection to the bowl also makes it easy to replace the float drain with an external manual or automatic drain.	Element top cap The top cap guides the air flow optimally into the cartridge and to the outlet to reduce pressure drop and the overall energy use of the filter.   inPASS™bypass Atlas Copco's revolutionary built-in bypass can be used to reroute the air during filter service to ensure an uninterrupted air flow. It's an invisible invention that will give you big investment and operational savings: • Service your filters at any time, even during working hours. • Secured air flow for your production during maintenance. • Reduced maintenance time as your air system doesn't need to be shut down. • Eliminates the huge cost of an external piping bypass. • Lowers the risk of leakages, resulting in lower energy costs.

Product Feature

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.

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.

 

DDp+ and PDp+ filters efficiently prevent dust, corrosion particles,micro-organisms, dirt and adsorption material from entering your compressed air stream.  These innovative filtration solutions are engineered to cost-effectively provide the best air purity and meet today's strict quality demands.

High-performance oil vapor filters

QD+ filters efficiently reduce hydrocarbons, odors and oil vapor in your compressed air to protect your investment, equipment and processes.

The macro-structured activated carbon will reduce the residual oil content through adsorption to less than 0.003 mg/m³. The pressure drop is low and remains constant during the lifetime of the filter.

 

Activated carbon towers for optimal oil vapor filtration

The high-efficiency activated carbon tower is capable of removing hydrocarbons, odors and oil vapor from compressed air. The activated carbon will, through adsorption, reduce the residual oil content to lower than 0.003 mg/m³. The pressure drop is low and stays minimal during the filter's lifetime.
