Nautilus filter technology

Nautilus filter technology

Building on many years of experience and backed by extensive in-house testing, our Atlas Copco engineers gained completely new insights into oil coalescing filtration. The result is our Nautilus Filter Technology based on unique, low-density filter media, with the sophistication and looks of a nautilus shell.

How does Nautilus Filter Technology work?

To explain nautilus Filter Technology, we use the metaphor of a forest. The trees are the glass fibers in the filter media – strategically placed so that nothing can get past them. Now think of a balloon – representing the oil and solid particles you want to filter from the air – trying to pass through the forest. The air current will move the balloon and it will get stuck in the leaves of the trees.

Best-in-class performance

Nautilus Filter Technology uses filter media of a lower density than in classic coalescing filter technology. Even though the glass fibers in the filter media are not placed as closely to each other as with classic coalescing filters, the forest is significantly larger, resulting in extremely low oil carry-over. The outcome is Best-in-class performance.

40% Pressure drop reduction

Less dense filter media used in Nautilus Filter Technology ensure much easier passage of the air. This reduces the pressure drop and leads to a filter that is much more energy efficient. Combined with the two-in-one filtration concept, the result is 40% pressure drop reduction.
