Product Description

Particulate Filtration Efficiency Testing Machine (PFE) For Medical Protective Clothing

Product Introduction Description:

Medical Protective Clothing Particulate Filtration Efficiency Tester is suitable for fast, accurate and stable detection of particulate filtering efficiency of various medical and daily protective masks, respirators,medical protective clothing, etc.

Medical workers are often infected and penetrated by splashes, blood, body fluids, secretions, excreta, etc. of infectious disease patients during their work. Medical protective clothing can help medical workers isolate bacteria and viruses to achieve protection effect. The particle filtration efficiency testing machine is to test the effect of protective clothing on the biological filtration and isolation of bacteria, viruses and other particles.

Equipment Usage:

The filtration efficiency tester of medical protective clothing is used for the testing of the particle filtration efficiency of daily protective masks, medical masks and respirators. Applicable to medical device inspection centers, safety protection inspection centers, labor protection inspection centers, drug inspection centers, disease prevention and control centers, textile testing centers, hospitals, masks and respirator manufacturers.

Testing Standard:

EN 1822-3:2012 EN 149-2001, EN 14683:2005
GB/T 19083-2010 5.4, GB/T 32610-2016, GB 2626-2019 6.3 ,GB 19082-2009 5.7, GB 19082-2009
YY/T 0469-2011 5.6.2, IEST-RP-CC021.1, NIOSH 42 CFR Part 84 ect.

Instrument Characteristics:

Efficiency detection: The brand high-precision dust particle counter is used to detect the concentration of upstream and downstream particles to ensure accurate and stable sampling;
Flow detection: The system test flow mainly provides dry and clean compressed air from the outside. There is a voltage-stabilizing and stabilizing device installed inside to ensure the stability of the detection flow, and the automatic control system is simple, fast and stable.
Aerosol generation: The Collision multi-nozzle design enables salt and oil testing on the same instrument to ensure fast and stable adjustment of the fogging concentration;
Test results; Equipped with a 7-inch touch display screen, the test results are directly displayed on the interface, the user can choose to directly or save the data;
Data port: external memory card, can export data, do not worry about data loss;
Resistance test: The resistance pressure difference of the filter material will be obtained through the static pressure ring of its upstream and downstream test chambers, and a high-precision imported brand pressure difference transmitter is used to ensure the accuracy and stability of the pressure difference;
Simple operation: The user only needs to place the filter paper in the fixture, press the button, and after adjusting the test flow, the system will automatically test the resistance and efficiency through the controller (PLC).
