Efficient air filter
Air purifier mainly by the filter and the shell of two parts. The basic requirement is to filter high efficiency, low flow resistance, can be used for a long time to reduce the cost of late supplies. One filter refers to the air filter, high efficiency air filter in the air purification industry plays a vital role.
High efficiency air filter is mainly used to capture 0.5um below the particles of dust and a variety of suspended solids. The use of ultra-fine glass fiber paper for the filter, offset paper, aluminum and other materials for the partition board, and wood frame made of aluminum alloy. Each by the smoke method test, with high filtration efficiency, low resistance, dust capacity and other characteristics.
High efficiency air filter can be widely used in optical electronics, LCD liquid crystal manufacturing, bio-medicine, precision instruments, beverage food, PCB printing and other industries clean air purification terminal air supply at the end. Efficient and ultra-efficient filters are used for the end of the clean room, with its structure can be divided into: a high efficiency, no partition high efficiency, high air volume efficient, ultra-efficient filters.
1. High efficiency air filter selection of the main control parameters Filtering efficiency, rated air volume, rated air flow under the initial resistance, dust capacity and so on.
2. According to GB / T6165-1985 "high efficiency air filter performance test method permeability and resistance" provisions of the method of inspection, the transmittance of ≤ 0.1% (ie, efficiency ≥ 99.9%) or particle size ≥ 0.1μm particles Counting transmittance ≤0.001% (ie efficiency ≥99.999%) of the filter for the efficient air filter.
3. High efficiency air filter commonly used filter material with ultra-fine glass fiber.
4. Air filter should meet the fire requirements, high efficiency air filter according to the degree of fire is divided into three: 1 filter, filter all materials are non-flammable, non-flammable materials should be consistent with GB8624-1997A level. 2 filter, filter media should be in line with GB8624-1997A class incombustible materials, partition plate, the framework can be used in line with GB8624-1997B2 grade combustible materials. 3 class filter, filter all materials available in line with GB8624-1997B3 level
5 design, according to the initial resistance of the double resistance, as the filter calculation resistance.
6 high efficiency air filter initial resistance shall not exceed 10% of the product sample resistance.
7 efficient air filter should not be used alone, high efficiency air filter should be set in the end of the purification air conditioning system.
8 dust capacity manufacturers should provide. High efficiency filter should be leaked at the factory. Other requirements are based on user requirements.

9 In the general non-parallel flow clean air conditioning system to use a combination of filter outlet.
