Commodity name: Bacterial Filtration Efficiency Tester

BFE-2020

Function
Test the filtration efficiency of respirator and filter media on bacteria.

Principle
The bacterial suspension enters the aerosol chamber through a peristaltic pump. It is atomized by high pressure air, and imported to two six level Anderson samplers, where the Bacteria is sampled.

Standard
YY0469-2011、YY/T 0969-2013、ASTMF2100、ASTMF2101、EN14683:2019、Q/0212ZRB003-2011

Characteristics
The structure of negative pressure cabinet ensures the safety of operators.
Two six level Anderson samplers (A, B).
The flow rate of bacteria can be set.
The special microorganism aerosol generator has adjustable atomizing flux, thus provide good atomization effect.
10.1-inch color high resolution touch screen, with intuitive interface, easy to use.
High brightness ultraviolet lamp for lighting and sterilization in the cabinet.
Leakage protection switch to protect operators.
