Particle Filtration Efficiency Tester ASTM F2299

Application:

Particle Filtration Efficiency Tester determines the initial efficiency of materials used in medical face masks to penetration by particulates using Latex Spheres.

ASTM F2299 PFE Tester measures the particle counting in size range 0.3 to 1.0μm, with airflow velocity 0.5 to 25cm/s.

 

Test Standard:

ASTM F2299, ASTM F2100

 

Test Principle & Method:

The aerosol generator of PFE Tester generates aerosol particles (latex sphere) with a certain concentration and size distribution, and passes through the tested sample at a specified gas flow rate, to test the concentration of particulates before and after test sample.

The percentage of particle concentration reduction is used to evaluate the filtration efficiency of the tested sample against particles.

 

Features:

Particle Filtration Efficiency Tester precisely controls humidity, airflow and aerosol concentration by adopting the following parts.

1, High-efficiency aerosol generator

2, High-precision multi-channel aerosol particle counter

3, Precision differential pressure sensor

4, Precision flow meter, humidifier, temperature and humidity sensor, etc.
