Mask BFE Testing Machine

Mask BFE Testing Machine
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.

Applicable Standards
  • ASTM F2100 standard specification for performance of materials used in medical face masks
  • EN 14683 standard that medical face masks in Europe are required to comply with
  • ASTM F2101 standard test method for evaluating bacterial filtration efficiency (BFE) of medical mask materials using Staphylococcus aureus biological aerosol
  • YY0469-2011 Technical requirements for surgical mask
  • YY/T 0969-2013 Single-use medical face mask
