T446 Respiratory Total Inward Leakage Test Machine

Respiratory total inward leakage test machine is designed to determine total inward leakage of respiratory according to EN 149. NaCl aerosol generator provides 100L/min air flow with particles. The leakage is a measured ratio by mean concentration of breathing zone and challenge concentration of inhalation and exhalation duration. Automatic control and calculated system provides easier and stable operation.
