DIN EN 149

Product catalog summary
Overview: The document describes a test bench designed for measuring breathing resistance in filtering masks according to standards DIN EN 149, DIN EN 13274-3, and CWA 17553. It simulates exhalation and inhalation processes and measures the resulting pressure in the mouth area using a Sheffield-testing-head.
Specifications:
  • Exhalation simulation up to 300 l/min and inhalation up to 120 l/min.
  • Breathing resistance measuring range of ± 20 mbar.
  • Power supply requirements: 110-230V / 50(60) Hz; approximately 600 W.
  • Vacuum supply: minimum 120 Nl/min at 90% final vacuum.
  • Device dimensions: 450mm x 325mm x 380mm (w x h x d).
Features:
  • 256 user-configurable test parameter sets for various standards and regulations.
  • Automated testing process with full automatic monitoring.
  • Internal data storage and RS232 printer interface for documentation.
  • Mass-flow-control-unit with reversible flow direction.
Components:
  • INTEGRA DFM 149: Measures inhalation and exhalation resistance with digital specification of settings and limit monitoring.
  • Sheffield-testing-head: Swingable up to 90 degrees in all directions, equipped with concentric aspiration, pressure, and measuring tube.
  • Vacuum Station: Includes two rotary vane pumps with a total capacity of 20m³/h and a final vacuum of -850 mbar.
  • Log Printer: Citizen CBM-910II, dot matrix technology, with a lifetime of 200 million letters.
Applications: The test bench is suitable for performing breathing resistance tests on masks according to specified standards, allowing for the detection of the influence of gravity on mask valves.

DIN EN 149-2

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...
