Single cartridge in-line filter brings numerous benefits

9th July 2019

A patent-pending single cartridge in-line filter is set to replace the traditional two-filter solution, commonly used in oil-injected compressor applications.

Filters are used to achieve suitable quality compressed air by decontaminating compressed air lines through the removal of concentrations of water, dust and oil (in the case of oil-injected compressors).

The new filter technology delivers a 40% lower pressure drop and removes contamination in compressed air down to 0.01 parts per million. In addition, it potentially reduces maintenance costs and has a number of environment-friendly benefits.

Atlas Copco’s UD+ single cartridge in-line filter encompasses its 2-in-1 nautilus technology, which allows the air to move through spiral pathways. The more open glass-fibre type filter media is wrapped around itself, creating a significantly larger filtration area. As a result of this technology the filter clogs more slowly, which reduces the pressure drop by 40% while retaining filtration efficiency. This combination technology has been achieved without having to increase the size of the filter housing.
