1.Product Description
With clean compressed air, the prepared NaCl solution or a similar solution such as DEHS/PAO are sprayed from the aerosol generator. After passing through a classifier (inertia principle), unneeded large particles are collected into the collection bottle, and particles meeting the requirements enter into the test system from the nozzle of aerosol generator.
2. Features
1.The aerosol emitted by the aerosol generator requires two treatments before reaching the tested filter material : 1. Produce aerosol salt particles by mixing with the heated gas (for salt spray). 2. Neutralize the static electricity carried by the aerosol through an electrostatic neutralizer, this treatment is to reduce the impact of particle loss and static electricity on the test results.
2.After the aerosol is processed by the above two treatments, it reaches to the surface of tested filter material at a certain flow rate (flow rate), and then the test procedure is started. For the filter efficiency test, the test time is very short, and it takes only a few seconds to complete the test. For the loading experiment, the experiment is relatively long. The particle counter or laser scattering photometer is used to measure the concentration or mass concentration of the upstream and downstream aerosol, and to calculate the filtration efficiency. At the same time, the pressure drop on both sides of the filter is measured by the differential pressure sensor.
