Particle Filtration Efficiency Tester

Product Details:
Particle filtration efficiency tester is mainly used to test the 0-99.999% grade filtration efficiency of self-priming filtered anti-particle respirators (including daily protective masks, medical masks, respirators, etc.) and the filtration efficiency and resistance of their materials. It is suitable for medical equipment inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, textile testing center, hospital, mask and respirator production enterprises, etc.

Application scope
Mask: Applicable to medical protective mask, medical surgical mask, general medical mask, etc. Particle through-rate efficiency testing
Protective clothing: applicable to daily work clothes, surgical suits, isolation suits and protective clothing, such as particle through-rate efficiency testing

Reference standard
GB/T 32610-2016 Technical specification for daily protective masks Appendix A (filtration efficiency)
GB 2626-2019 Respiratory protective equipment-self-priming filtered anti-particulate respirator 6.3 chapter (filtration efficiency)
GB 24539-2009 Protective clothing Chemical protective clothing general technical requirements 5.3.3.5 Resistance to solid particles penetration
GB 19082-2009 Medical disposable protective clothing technical requirements 5.7 chapter (filtration efficiency)
GB 19083-2010 Medical protective masks technical requirements 5.4 chapter (filtration efficiency)
YY 0469-2011 Medical surgical masks

Functional description.
1 The whole test equipment adopts negative pressure system.
2. Air and aerosol enter through the mixing barrel and pass through the filter media according to the flow rate specified in the standard (specimens are sealed through a special fixture)
3. Through the two photometers to detect the concentration of the specimen upstream and downstream, to calculate the filtration efficiency. The pressure difference between the upstream and downstream of the specimen is detected by the differential pressure gauge.
4. Through the pump to achieve the rated flow rate.
5. Generate standard aerosol material by aerosol generator.
6. Operation of the equipment and calculation of efficiency and resistance through PLC and display.
