How do I check the ANKOM Dryer filter for proper airflow?

When using the ANKOM Rapid Dryer to dry acid hydrolysis samples, the airflow through the special hydrolysis filter (Part #: RD2) will eventually become too limited and the filter will need to be changed.

To check the air filter for proper airflow, refer to HCl Service Procedure RD Filter Check for Proper Air Flow (HS011).
