Currently, for many domestic manufacturers of high efficiency filters, the establishment of testing methods, and adhere to the test by Taiwan, which is to change the reputation of domestic high efficiency filter the most urgent task is to improve the competitiveness of the most direct means of products, manufacturers are now the most Easy to do.
Adhere to the test will increase production costs (test costs, scrap), the price will be slightly increased, as long as you can prove that each high efficiency filter has been tested, the user will believe your product.
Comparison of fiber diameter, rough identification filter performance
In the filtration process, the fiber is an obstacle to intercept dust. Fiber fine, unit volume within the fiber number; fiber, filter efficiency is high.
Airflow around the fiber motion energy consumption, the performance of fiber resistance to airflow. Two filter materials of the same efficiency, crude fiber resistance, small fiber resistance.
In addition to being blocked by the fiber dust, dust can also be caught early to stop living, so the fiber surface of the dust to “dendritic structure” loose accumulation, fiber is “dry”, dust is the “branch.” Fiber and more, can form on the dendritic structure, the unit area can accommodate more dust, the filter on the long life. Fiber, air between the fibers when the small, formed by the dust on the dendritic structure on the solid, dust was blown off the secondary pollution caused by the possibility of small.
The same thickness, the same degree of fluffy two filter media, fine fiber filter filtration efficiency, fine fiber filter capacity of dust capacity.
The same efficiency, the same structure, composed of two different fiber filter material, fine fiber filter resistance is low.
The air conditioning system itself requires a good filter
Over the years, air-conditioning designers according to the needs of users to select the filter, and now, people realize that the central air-conditioning itself should have a good filter to protect.
