Degassing Modules for Jet Ink

Degassing Modules for Jet Ink

DIC's hollow fiber membranes are suited to degassing jet inks because they only allow gases to permeate the membrane without letting liquids through. These modules can also be installed in inkjet printers by the development of small, low pressure loss products.


  • Optimal structure for degassing/aeration (DIC's Hollow Fiber Membrane)
  • With a broad lineup, suited to various ink types and applications
  • Low pressure losses and space savings are realized by the proprietary internal structure

Degassing Requirements in Jet Inks

Dissolved gas changes into bubbles from repeatedly increasing and decreasing pressure by a piezo element or from heating.
The result of which is...

  1. Bubbles block nozzles and they fail to fire.
  2. Piezo element pressure is dispersed by bubbles, causing a misalignment of the ink landing position.

These problems are solved by degassing.

Model List

Please select the optimal model number according to the usage conditions like the type of ink used and the treatment volume, and the target degassing level. DIC can also select the appropriate model for you. Please feel free to contact us.
