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.
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.
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.
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.
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
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.
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.
