Product Description

TN-BFE   BFE Test Machine

INTRODUCTION

This system is specially used to detect the percentage of bacterial suspended particles filtered from mask materials. The filtration efficiency of the mask should not be less than 95%.

This system not only conforms to the requirements of medical surgical masks technology YY appendix B in 0469-2011 test method for filter efficiency (BFE) bacteria first b. 1.1.1 test instrument, but also conforms to the American society for test materials ASTM F2100, ASTM F2101, the requirements of the European EN 14683 standard, and innovative improvements were made on the basis of this, with double pneumatic contrast sampling method at the same time, improve the precision of sampling, It is suitable for measuring and testing departments, scientific research institutes, mask manufacturers and other relevant departments to test the performance of mask bacterial filtration efficiency.

FEATURES AND BENEFITS

1.Embedded high-speed industrial microcomputer control, with large industrial level high brightness color touch screen.

2.USB universal interface, support U disk data storage.

3.Front switch type glass door, cabinet with built-in high brightness lighting, easy for test personnel to observe and operate.

4.The inner layer of the cabinet is made of stainless steel. The outer layer is sprayed with plastic and cold-rolled.

5.Negative pressure test system to ensure the safety of operators.

6.Built-in leakage protection switch to protect the safety of operators.

7.Built - in peristaltic pump in the negative pressure cabinet, A, B, six Andersen, peristaltic pump flow can be set.

8.The flow rate of night spray of special microorganism aerosol generator can be set, and the atomization effect is good.

9.Movable feet for easy handling.
