China Automated Filter Tester

MODEL NO.:

AFT-120B

APPLICATION:

AFT-120B NIOSH 42 CFR 84 Automated Filter Tester is used to determine the filter efficiency of dust-proof masks and particle-proof filter materials. The air source of the instrument is compressed air and gasholder to supply constant-pressure and constant-flow airflow; PTFE filter core purifies the airflow and precise valves adjust air volume and aerosol density with stable airflow and high sensitivity; Multi-level impingers provides even size particles and stable-density aerosol; particle counter has high precision and more stable measuring data. Electric charge neutralizer can completely neutralize all electric charges in aerosol for more precise test data. The instrument is widely used in manufacturing factories, inspection units and scientific research institutions relating to dust-proof products.
