This instrument automatically measures inhalation and exhalation resistance of half-mask respirators (e.g., FFP1/FFP2/FFP3 masks) under controlled airflow conditions, ensuring compliance with EN149:2001+A1:2009, GB2626, and GB/T32610 standards. It simulates human breathing patterns via an adjustable standard headform to evaluate real-world performance.
Applications
Certification Labs: Validates FFP mask compliance for CE marking.
Manufacturing QC: Batch testing for inhalation/exhalation resistance in medical, industrial, and N95/KN95 masks. R&D: Optimizes breathability in new respiratory designs.

What is EN149 standard ?
EN149 is a European harmonized standard that specifies minimum requirements for filtering half masks (e.g., FFP1/FFP2/FFP3 masks) used as respiratory protective devices against particles. It covers:
EN149 mandates rigorous evaluations, including: Inhalation/Exhalation Resistance: Measures breathing resistance at airflow rates of 30 L/min, 95 L/min, and 160 L/min.
