Koganei FDH Series Tube Dryers

The FDH Series Tube Dryers are compact, environmentally friendly air dryers that use hollow fiber membrane technology to continuously dehumidify compressed air without electricity, heat generation, or condensate drainage. Moisture is removed as water vapor through the membrane and exhausted with purge air, eliminating the need for drain ports or condensate management.

Designed for point-of-use installation, the FDH Series provides stable dehumidification in a lightweight, space-saving form factor. A built-in dew point indicator allows real-time visual confirmation of air dryness through color change, simplifying daily inspection and maintenance. With no moving parts and no power requirement, the FDH Series offers reliable, low-maintenance operation for clean air supply in automation and pneumatic systems.
