Intended use
The device is manufactured and tested according to good engineering prac-
tices and the recognized safety rules. In order to avoid hazards to yourself or
third parties and damage to the device and other assets, only use the device
properly and as intended.
The filter media test rig is intended to be used only for pressure-tight, leak-
age-free testing of convex and flat, air-permeable filter media. The differen-
tial pressure at the clamped-in filter medium may not exceed 5000 Pa.
Testing determines the following characteristic values related to the filter:
• Efficiency grade and fractional efficiency grade when collecting particles
on the filter at a defined air volume flow rate
• Differential pressure of filter medium at a defined air volume flow rate
• Functioning of valve on FFP masks
The device is intended for use indoors.
The device is intended to be used only by the following persons:
• Persons who are familiar with activities in the field of particle measuring
technology based on their education or experience.
Any use other than the intended use is prohibited. The manufacturer as-
sumes no liability for damages resulting from this. All warranty claims are
voided if changes are made to the device, including in the course of assem-
bly and installation.
All corresponding documentation must be observed for any work on the de-
vice.
