The Parker Balston Membrane Air Dryer provides reliable and energy-efficient removal of water vapour from compressed air systems using advanced membrane separation technology. By combining high-performance coalescing filtration with a proven membrane drying process, the system delivers clean, dry compressed air with pressure dew points as low as -40°F (-40°C).
The drying process begins with superior coalescing filtration, which removes oil aerosols, liquid water and particulate contaminants from the compressed air stream. This filtration stage protects the membrane module and ensures optimal drying performance.
Once filtered, the compressed air passes through a selective membrane fibre bundle. Water vapour permeates through the membrane walls and is carried away by a controlled purge airflow, leaving dry compressed air at the outlet. This continuous process provides reliable moisture removal without the need for moving parts, electrical power or complex regeneration cycles.
Because the membrane drying process operates continuously and requires minimal components, Balston membrane dryers offer low operating costs, minimal maintenance requirements and high system reliability. The compact design also makes them easy to install directly at point-of-use locations where dry air is required.
These dryers are particularly well suited for applications requiring low dew point air in smaller flow systems or remote installations, where traditional desiccant dryers may be impractical. Their robust design ensures dependable operation across a wide range of industrial and laboratory environments.
Typical applications include instrument air systems, pneumatic equipment, electrical cabinet pressurisation and analytical instrumentation, as well as compressed air supplies used in hazardous areas and laboratory environments where consistent dry air is critical.
With its compact design, reliable membrane technology and low maintenance requirements, the Parker Balston membrane air dryer provides an efficient solution for delivering clean and dry compressed air in point-of-use and specialised applications.
