The Atlas Copco UD+ Oil Coalescing Industrial Compressor Filter uses wrapped filtration technology to filter aerosols and solid particles under wet conditions from compressed air systems, which may arise from lubrication of the compressor element, intake air, and/or the compressor installation itself. The UD+ combines two filtration steps (DD+ and PD+) into one, helping to meet the quality requirements of diverse applications and save energy. The UD+ filter provides the same air purity as a DD+-PD+ filter train with a lower pressure drop. It is ideal for applications where space is at a premium, reducing environmental footprint, system complexity, and installation space.

The inPASS™ bypass option is also available for all models. The built-in bypass can be used to reroute the air during filter service to ensure an uninterrupted air flow, allowing for service during working hours, reduced maintenance time as the air system will not need to be shut down, lower leakage risk, and elimination of a need for an external piping bypass.
