What is BFE for mask?
BFE measures the filtration efficiency of a mask using viable (live) particles (bacteria) that vary in size from 1 to 5 microns. What is PFE - Particle Filtration Efficiency? PFE measures the filtration efficiency of a mask using nonviable (nonliving) particles that are fixed in size from 0.1 micron to 1 micron.

Mask BFE Testing Machine is used to test the percentage of material containing bacterial suspended particles at a specific flow rate.

Features:
1. Mask BFE Testing Machine: negative pressure test system, can protect the safety of the operator.
2. Peristaltic pump built in the negative pressure cabinet, A, B channel 28.3L/min.
3. The flow rate of the peristaltic pump can be set.
4. BFE Tester atomization effect is good.

Mask BFE Testing Machine test principle:
Bacterial filtration efficiency Tester consists of aerosol generation system, aerosol chamber and aerosol transmission device, negative pressure cabinet, 28.3 l/min carbon sampler and other components.The entire detector is controlled by the console.The console adopts microcomputer control system to coordinate and control the work of aerosol generating system, transmission system, negative pressure cabinet and sampling system, and display the working status in real time.The entire measurement work is done automatically.
