Atlas Copco - Membrane Air Dryers - SD, SDR

Optimal safety and efficiency

Atlas Copco’s SD membrane dryers with pre-filters 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, SD dryers can perform in a wide variety of harsh and critical conditions. Two models are available to offer you the exact air treatment you require.

Key features

• Versatility

SD dryers perform well in a variety of environments ranging from small spaces, applications that require flexible mounting and high vibration areas to spaces with widely fluctuating temperatures

• Safety assurance

Our SD dryers meet strict safety and environmental requirements. This includes low flow environments, areas without an electrical supply, explosion-proof facilities, noise-sensitive and corrosion-sensitive areas. No electricity required

• Critical environments

As they are not powered by electricity, SD dryers can function safely in explosion-proof environments such as laboratories

• Meets all requirements

Offering different dewpoint suppressions for the different models, the SD dryer can serve all kinds of performance requirements

• Low noise levels

Thanks to their quiet operation, you can use SD dryers close to the workplace

• Save energy

Thanks to its straightforward design, your compressed air doesn’t make any twists or turns within the housing. The result: minimal pressure drop and the highest drying efficiency
