The purity of breathing air is essential in both industrial and medical applications.
That’s why facilities rely on breathing air purification to help protect their teams and meet international standards.
Donaldson’s breathing air systems are independently tested by the Institute for Environment & Energy, Technology & Analytics (IUTA). Their results confirm compliance with the European Pharmacopoeia Monograph 1238 limits for contaminants such as carbon monoxide, sulfur dioxide, nitrogen oxides, oil, and water vapor.

Ultrapure Breathing Air Purification Packages
The Ultrapure Smart ALG and Ultrapure HL-ALG breathing air purification packages combine advanced filtration and adsorption technologies in compact, modular systems

Ultrapure Smart ALG systems
The Ultrapure Smart breathing air systems are purification units based on Ultrapac Smart adsorption dryers to supply breathing air. The purification package removes particulates, liquid oil, oil vapor, CO, CO2, NOX, and SO2 as a plug & play solution package. Installation and maintenance costs can be significantly reduced by using this compact purification unit to generate breathing air.

Ultrapure HL ALG systems
The Ultrapure HL-ALG range of heatless regenerated adsorption dryers delivers compressed air at pressures up to 16 bar. To meet your needs even in high ambient temperatures or environments with elevated humidity levels, the drying process — based on adsorption of water molecules out of a gas stream using hygroscopic desiccant materials — can achieve pressure dewpoints of -40°C or lower at 7 bar.
