Application:

Mainly used for the performance testing of respiratory protection products, disposable masks, filter medium, the security testing which is 

suitable for such products, basic filtering performance evaluation and guidance for the development of new products.

Mask filter performance tester is easy to operate. Using oily aerosol and solid  photometric detection technology, it can automatically 

measure the filtration efficiency and pressure drop of filter materials, filter masks and filter elements in a wide range of volume flow.

Key Feature：

1. Negative pressure testing system, which can protect operator’s safety.

2. Peristaltic pump was built in the negative pressure cabinet, A & B two routes 6 level Andersen sampling head.

3. The flow speed of peristaltic pump can be set.

4. The spray flow of bacterial liquid inside the special microbial aerosol generator can be set.

5. Good atomization effect.

6. Embedded high speed industrial microcomputer control.

7. 10.4 "industrial high brightness color touch screen display.

8. USD connector, support USB data archived

9. High brightness light installed in the cabinet.

10.Switching type glass door in front of the machine, easy to observe by the operator.
