The above pressure is the recommended value when using the module at 15-30

please contact DIC for more details.
※
The above vacuuming pressure is not suitable for every application. Depending on
applications, composition, and target degassing performance, the most suitable
vacuuming value may be different from the above value.

2.
For Non-Aqueous Liquid.
Recommended Vacuuming Degree: We recommend setting weaker degrees (higher
in
value) than the recommended saturated vapor pressure of the liquid.
Ex
:
In cases where saturated vapor pressure is 8kPa(abs), we recommend a weaker vacuum
degree than 10kPa(abs).
As the vacuum pressure degree approaches a perfect vacuum, degassing
performance is improved. However, if the vacuum pressure degree is too strong
yet close to perfect pressure, liquid may evaporate and penetrate through the
membrane. As a result, the composition of liquids may change. Therefore, DIC
recommends following the exact vacuum pressure degree.
