Breathing filter evaluation filtration performance salinity tester Shanghai Chengwei

Respiratory filter evaluation filtration performance salinity tester one, the application of short-term air sodium chloride particles challenge test method, to evaluate the filtration performance
of respiratory system filters used to filter breathing gas.
This section applies to respiratory filters
for clinical respiratory systems.
This section does not apply to other types of filters, such as filters used to protect vacuum sources or gas sampling lines for the filtration of shrinking gases or for the protection of biological respiratory measurement test equipment
