Blue and White Filter / Air Inlet Filter
Blue and White Filter also called, Air Inlet Filter, Pre Filter Media, coarse filter media.
hetic particles larger than 5μm; the air control system of general ventilation equipment filters the filter structure as pre- or coarse fiber; the dust-free woven filter layer structure composed of combined resistance PET is used, according to the extensive characteristics of dust, use Various characteristics, using the size of the dust to be blocked in the range, the high quality of the dust is more effectively used; it has the measurement volume and low resistance, economical practicability;
· Contains no silicon and is resistant to chemicals such as chemical solvents and acid fumes;
· Meet the fire classification standard DLN53438-F1 in Europe and UL900-class2 in America;
· Mostly used for plate type and dense folding filter;
· With paper frame galvanized frame or aluminum frame, etc.
It can be cut out according to the size of the air supply port and installed directly to the air supply port. It can also be made into plate type, folding type and bag type filter. After waterproof treatment, it has the function of cleaning. It can be used for automatic coiling filter unit with single side net, coiling core and paper tube.
Under the condition of rated air volume, it can be used normally for 1~2 months, that is, the filter cotton needs to be replaced; Or when the resistance of the filter cotton reaches more than 200Pa, the filter cotton must be replaced; If the filter cotton is washable, replace the filter material, can be washed with water or containing neutral detergent solution, compressed air dry or cool dry, and then change; It can be cleaned twice at most, that is, new filter cotton must be replaced, and each cleaning, the filtering efficiency will be reduced by 15%; If the dust concentration in the service environment is large, the service life cycle will be reduced.
Blue and White Filter is suitable for various industrial uses, such as pollution prevention, public construction, air conditioning, electronics, pharmaceutical, food industry, etc.
It is also suitable for coarse dust filtration and pre-filtration of medium-effect air filtration system.
Pre filter media a big category, It covers Air intake filter, Floor filter, paint stop filter, fiberglass filter, non woven filter, Activated Carbon Filter, Flame-retardant filter media, synthetic filter media, etc.

According to the statistics of the China Iron and Steel Association, 75 large and medium-sized iron and steel enterprises included in the statistics from January to October achieved a profit of 69.34 billion yuan and a profit rate of only 2.8%, which is lower than the average profitability of China's industrial sector. Xinhu Futures analyst Weng Mingxiao said that the energy-saving and emission-reduction measures in 2010 made the inventory effect of last year significant, laying a good foundation for steel prices next year. At the same time, under the environment of rising costs and gradual domestic demand, steel prices will stage a bull market in the first half of 2011. The rise in steel prices will increase the profits of steel mills, which will gradually increase the investment in technological transformation of enterprises and increase the purchase of equipment such as steel analysis instruments. As a result, the trend of steel analysis instruments naturally increases. 
The sales volume of steel analysis instruments is closely related to the good and bad conditions of the steel market. It is reported that Rio Tinto and Vale have already issued iron ore agreement prices for domestic steel mills in the first quarter of next year, which is an increase of 7.6%. According to Platts, Brazil's 66% grade Carragas iron ore price will be around 172 US dollars/kton, while Rio Tinto's 62% grade PB fines will exceed US$136/tonne. By then, the cost of tons of iron will probably rise by around RMB 100/ton. With the pressure of cost, the domestic steel mills are constantly being squeezed into profit margins.
