Next generation of filtration solutions

Atlas Copco has launched the UD+ coalescing filters, which combine two filtration processes in one product. The UD+ is unique in the market and offers energy savings, efficiency gains and reliably clean compressed air.


40% energy savings

A 40% lower pressure drop than the conventional line filter combination results in 40% higher energy efficiency thanks to our unique Nautilus filter technology.

Small footprint

The two-in-one filtration concept reduces installation space and complexity, making these filters particularly suitable for applications where space is at a premium.

Save money

Install the UD+ to enjoy significant cost savings compared to conventional filters.

Pure air

Air purity is equal to that obtained using two conventional filters in line, thanks to the design of UD+ filters and the media used.

No risk of cracks in filter media

Nautilus filter technology runs no risk of cracks in the filter media because the filter media are wrapped around the filter.
