Membrane Dryers
Untreated compressed air always contains water. As water is incompressible, the amount of moisture per volume increases when air is compressed. The maximum amount of moisture per volume of air (the so-called holding capacity of moisture in the air) is however limited for a certain temperature. Condensation forms when air is compressed.
Pneumatech Membrane Dryers use the principle of selective permeation (separation) of the air components. This is achieved by a hollow-fiber membrane, where moisture can diffuse through the fine pores of the fiber bundles. When differences in moisture concentration arise between the inside and outside of a fiber membrane, moisture is transferred through the membrane surface to equalize the moisture concentration on both sides of the membrane. Part of the dry air is used as purge air in order to remove the moisture from the incoming wet air.
Membrane dryers for compressed air have a compact size. They are easy-to-use and offer a simple drying solution for your compressed air needs. They operate without electricity and come in different types of membranes tailor-made for your compressed air and dew point requirements.

M POU 2-16 Membrane Dryers
Membrane dryers for small compressed air needs.
Pneumatech offers an easy-to-use and simple drying solution for small compressed air needs. Pneumatech point-of-use membrane dryer does not require any power source, is compact and easy to install. This makes the dryer suitable for various smaller compressed air applications where a higher degree of dehumidification is required, such as laser machining tools, precision measuring equipment, gas analyzers and small gas generators.
The pressure dew point achieved by membrane dryers is dependent on the inlet temperature of the compressed air; but can go down to -40°C/-40°F. This is achieved by a hollow-fiber membrane, where moisture can diffuse through the fine pores of the fiber bundles. When differences in moisture concentration arise between the inside and outside of a fiber membrane, moisture is transferred through the membrane surface to equalize
the moisture concentration on both sides of the membrane. Part of the dry air is used as purge air in order to remove the moisture from the incoming wet air.

PMD 3-35 Membrane Dryers
The Pneumatech PSMD 3-35 combines compressed air drying efficiency with zero maintenance for the most demanding applications. Because it is not powered by electricity, our membrane dryer ensures safe operation in harsh and critical environments such as laboratories. Ultra quiet, it is also ideal for point-of-use installation and small spaces.
The PSMD does not have any moving components, which makes it easy to use and 100% maintenance-free. Thanks to its very low pressure drop and purge air use, it also maximizes energy savings. The PSMD offers the choice between two types of membranes to achieve the pressure dew point suppression (32°C/90°F or 55°C/131°F) that works best for you.
- No Maintenance
- Energy Efficient
- Demanding Conditons
PMD 1-7 Membrane Dryers
High performing compressed air dryer for your dew point requirements
With its pre-filters, Pneumatech PMD dryers remove oil particles and moisture from compressed air in the most demanding conditions, at the lowest energy cost at two possible dew points. Thanks to their special fiber technology, PMD dryers ensure the lowest pressure drop and purge air loss for the highest possible efficiency, saving you time and money.
From small spaces to environments with fluctuating ambient temperatures, PMD dryers can perform in a wide variety of harsh and critical conditions. PMD dryers also come with different types of membranes, allowing you to choose the exact air treatment you need, and the dew point your operation requires. With an innovative design, PMD dryers provide the quality of air that will increase the reliability and energy efficiency of your production.
Compressed air dryer technology at its best to reach the pressure dew point needed: The thousands hollow fibers with a special inner surface are extremely efficient. The inner coating ensures efficient separation between water vapor and gas molecules of the compressed air. Reliable performance and extraordinary low pressure loss are the results of this membrane dryer technology.
