Features: With the test bench for breathing resistance on filtering masks according to DIN EN 149 and DIN EN 13274-3 as well as community face coverings according to CWA 17553, exhalation and inhalation processes with a static flow of up to 300 l/min (exhalation) and up to 120 l/min (inhalation) can be simulated. At the same time the resulting pressure in the "mouth area" of the Sheffield-testing-head for breathing resistance can be measured. This enables all breathing resistance measurements to be realized according to DIN EN 149, CWA 17553 and DIN EN 13274-3. The INTEGRA DFM 149 test device...
