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.
