Test area

100cm²

Aerosol concentration

(12 ~ 20) mg / m³ (salinity), (50 ~ 200) mg / m³ (oily)

Test temperature (25 ± 5) ℃
Relative humidity (30 ± 10)%
Gas source flow 198L / min (0.6Mpa) at 550kPa

 

 

Oil mist method:


The dry oil-free compressed air enters the aerosol generator at a certain flow rate to produce the aerosol with a certain particle distribution. After screening by the cascade impactor, the particles with the particle distribution meeting the standard requirements are discharged from the aerosol outlet and enter the test pipeline.
During the test, the number of particles in the upstream and downstream of the filter material is monitored, and the whole test process is conducted with a certain flow rate or air volume.


Salt spray method:


The dry oil-free compressed air enters the aerosol generator at a certain flow rate to produce the aerosol with a certain particle distribution. After screening by the cascade impactor, the particles with the particle distribution meeting the standard requirements are discharged from the aerosol outlet and enter the test pipeline.
Because the salt aerosol has static electricity, it is necessary to neutralize the salt aerosol. And for the salt aerosol, it needs to be heated to produce salt particles. The method is as follows: mixing the aerosol with heating gas, and then evaporating the water in the aerosol to produce salt particles;
