Atlas Copco SMD 3-32 membrane air dryers ensure the highest compressed air quality. Extend your equipment lifespan and increase efficiency with preventative air treatment.
Extend your equipment lifespan and increase efficiency with preventative air treatment. Atlas Copco SMD 3-32 membrane air dryers ensure the highest compressed air quality.

Atlas Copco SMD membrane dryers with a pre-filter remove moisture, oil and particles from compressed air in the most demanding conditions. The dryers deliver the lowest pressure drop and purge air loss at the highest possible efficiency – saving you time and money.
From small spaces to environments with fluctuating ambient temperatures, SMD dryers can perform in a wide variety of harsh and critical conditions.
Available under two PDPs variants (32°C / 55°C) to offer you the exact air treatment you require.

SMD membrane dryers contain thousands of hollow fibers with an innovative inner coating. Compared to conventional membrane dryers, this unique coating increases the separation efficiency between water vapor and oxygen and nitrogen, giving an unprecedented low air leakage and the lowest purge air loss. With our optimized fibres we stand no compromise in reliability.
Critical environmentsAs they are not powered by electricity, SMD dryers can function safely in explosion-proof environments such as laboratories. Meets all requirementsOffering different dewpoint suppressions for the different models, the SMD dryer can serve all kinds of performance requirements. Low noise levelsThanks to their quiet operation, you can use SMD dryers close to the workplace. |

Excellent product from Atlas Copco~
Our production environment has fluctuating temperatures, but this membrane dryer handles it all effortlessly. The unique hollow fiber technology delivers consistent dew point performance. The low pressure drop is saving us energy costs, and the quiet operation means we placed it right next to our workstations without any disruption.

Perfectly dry air, with zero worries.
We installed the SMD 3-32 in our offshore lab, and the reliability is outstanding. The fact that it runs without electricity is a huge safety plus in our explosive-risk environment. We’ve measured the purge air loss, and it’s remarkably low. Our instruments are now protected by perfectly dry air, with zero worries.
