Testing procedure
There are two ways to place respiratory masks in the filter holder:
• With the exterior (curvature) facing up: simulates inhalation.
• With the exterior (curvature) facing down: simulates exhalation.
The software contains the following testing routines:
• Efficiency testing with a saline aerosol
• Efficiency testing with an oil aerosol
• Breath resistance testing without aerosol
• Testing of valve on FFP masks without aerosol
Unusually shaped respiratory masks can be placed on the included universal
filter adapter and tested there.
Flat filter media can be placed on an included support grid and tested there.
