How do I test the filter resistance?
The use of dust filter more life, more resistance. When the resistance to design does not allow the degree of xf2nby, early efficiency air filters on the end of life. Sometimes, too much resistance will cause the dust early efficiency air filter has captured the dispersion, two times the pollution, primary air the filter is also useless.
Most of the captured dust is concentrated on the windward side of the filter material. The larger the filter area, the more dust it can contain, and the longer the service life of the initial effect filter
The dust captured by the dynamic performance creates additional resistance to the airflow, so the resistance to the primary effect air filter is gradually increased. The captured dust forms a new barrier, so the filtration efficiency is slightly improved
The resistance of the primary air filter increases with the increase of air flow rate. By increasing the area of the filter material, the relative wind speed through the filter material can be reduced, and the resistance of the initial effect air filter can be reduced
