Mask Bacterial Filtration Efficiency (BFE) Detector GT-RA02B


Product Introduction


Mask Bacteria Filtration Efficiency Tester,are mainly used for testing the bacterial filtration efficiency performance of masks applicable to metrological verification departments, scientific research institutes, medical mask production units and their related testing departments. It has the characteristics of fast and accurate measurement of the bacterial filtration efficiency of masks [BFE].


The Mask Bacterial Filtration Efficiency (BFE) Detector is composed of a biological aerosol generating system, aerosol chamber, aerosol delivery device, negative pressure cabinet, and 28.3LPM Anderson sampler. The entire detector is controlled by the control system. The console uses PLC+Labview to coordinate and control the work of the aerosol generation system, transmission system, negative pressure cabinet, and sampling system, and displays the working status in real time, and the entire measurement work is automatically completed.

1.Standard test cabinet, touch screen + PLC system is easy to operate.
2.The sampler is Anderson level 6 sampler.
3.The chamber is made of quartz glass with a length of 600mm and a diameter of 80mm
4.The sprayer is made of quartz glass which is corrosion-resistant.
5.The vacuum pump: pumping flow 57L/Min.
6.The test tube holder is made of stainless steel, durable, humanized design, easy to use;
7.Add fixed tooling on the base of the sampler to prevent the sampler from sliding
8.The test cabinet is equipped with exhaust device to keep the negative pressure all the time.

9.The door of the test chamber is equipped with large observation window and operation gloves, so as to observe during the test and operate the test.
