The diffusion effect of small -particle size dust (Brown movement) is obvious, the wind speed is low, and the airflow has a long time to stay in the filter material, and there will be more opportunities to impact obstacles in the dust, so the filtration efficiency is high. Experience shows that for high -efficiency filters, the wind speed is reduced by half, the passing rate of dust will be reduced by nearly one magnitude (an increase in efficiency value by one 9), the wind speed increases double, and the pass rate will be increased by one magnitude (the efficiency is reduced by one 9).

Shandong Xinli || The choice of air filter Shandong Xinli-Air Purification Product Professional Service Provider Xinli Environmental Technology (Shandong) Co., Ltd. originated in 2010 and focused on the purification industry for 12 years to provide customers with high-quality air filters and other products. Provide a good purification environment for the normal operation and maintenance of the office, architecture, and production of customers.

Xinli Environment is in the \"Global Quality Air Purification Overall Solutions\" as the business latitude, the air purification industry market is guided, increases funds, equipment, and human investment, and is committed to the development of air purification industry. There is a modern production workshop. There are a number of branches in the country. The service industry involves medical, electronic, semiconductor, biomedicine, precision manufacturing, etc. Waiting for a well-known enterprise. Main business: self-belt fan filter unit (FFU), air filter, liquid tank filter, chemical filter, transfer window, wound filter, air supply, layer flow cover, wind shower, purification shed , Clean engineering, etc., and provide an indoor air quality control solution to provide air quality control equipment OEM. The independently developed FFU control system is evaluated as \"International Leading \". DC FFU and intelligent control systems can more comply with user needs, not only reduce operating costs, can be subjected to operational costs, can be independently monitored and controlled independently, but also thermal humidity sensors and differential pressure sensors, automatic adjustment of fan speeds with differential differences . There is a great advantage in distribution costs, energy consumption, and operating costs. Our air filter products have high-volume dust, stable performance, high daily pleasure rate, and support non-standard customization, OEM processing. Hotline: 4006883551 / 13165316200

According to the high-efficiency filter national standard GB13554-92 and GB13554-2008 to formulate quality standards: [Packaging] The outer packaging is intact, no hit, cracking traces; internal packaging (plastic bag) should be intact, foam angle, foam board Complete, model, air volume, airflow flow direction should be complete, accurate, complete, and product certificate is available. [Framework] High-efficiency filter frame surface has no obvious pollution, no unevenness, scar, no scratch, coating, no flakes, no burr, rust, high-efficiency filter frame (on one side of the viscosity) should be flat, no significant deviation; The high-efficiency filter frame strength should meet the requirements, such as placing the surface, shake, the frame has no deformation, and the shake occurs. [Seam] The seal between the high-efficiency filter paper and the frame should be strict, no gaps and holes; the sealing strip between the high-efficiency filter and the frame, should be connected, unfained, visual flat, high efficiency filters and boxes

The junior high-efficiency air filter refers to air filtration units, generally used in clean workshops, cleansing plants, laboratory and clean rooms, or for electronic mechanical communication equipment. There is an initial filter, a medium-role filter, an efficient filter and a sub-efficacy model. Various models have different standards and performance. ◆ Reasonably determine the efficiency of the filter at all levels, the last level filter determines the degree of air purification, and the upstream level filter mainly protects the lower wind filter to extend its service life, or protect the air conditioning system. To ensure its normal work. In the air conditioning design, you should first determine the efficiency of the last level filter according to the user's cleanup requirements, then select the protective filter, if this level filter needs to be protected, it is necessary to add a filter in its upper wind. Protect the filter collective \"pre-filter \". The efficiency of each of the filters should be properly matched. If adjacent two levels
