1、 Introduction to V-shaped high air volume high-efficiency filter
V-shaped bed filters are divided into medium and high-efficiency filters, as well as high-efficiency filters. This product has been specially designed and developed to meet the needs of low resistance and large amounts of air. The V-bed high-efficiency shu series can achieve a wind speed of 2.5 m/s (500 fpm) with an initial resistance of 250 Pa. The filtration material of the V-bed filter is imported ultrafine glass fiber. After folding and forming without using separation technology, place it in a V-shaped frame.
Compared with traditional types with partitions and high air volume, it has the following characteristics.
The service life is longer, and the unfolded area of the filter material is twice that of traditional types, while a larger filter area can provide a longer service life.
As the area of the filter material increases, the filtration rate decreases, thereby improving the filtration efficiency. This makes it easy for efficient products to reach 99.99% of 0.3um.
The conventional initial resistance has the same air volume, lower operating costs, and is 1.3 times that of a V-bed, thus having energy-saving effects.
2、 Characteristics of V-shaped high air volume high-efficiency filter
Box type activated carbon filter - V type chemical filter uses granular and columnar activated carbon and undergoes chemical formula treatment. Activated carbon is made from coconut shells and has an activity of over 60% in tetrachloride. The outer frame can be made of waterproof cardboard, galvanized iron or aluminum frame, and stainless steel. The chemical filter element is equipped with granular activated carbon with a large specific surface area (2000 or more), high adsorption capacity and capacity, and modified activated carbon for acidic gases (H2S), alkaline gases (NH3), etc. Can absorb specific gases. It is also known as a chemical filter because it is a series of molecular level gases (AMC).
Box type activated carbon filter product performance:
Ultra fine synthetic fibers and special spectral absorption media can simultaneously remove gas molecules and dust pollution and improve air quality.
Type A: Adsorption of VOCs and ozone.
Type B: Can absorb acidic toxic gases (SO2, NO2, H2S, HCl, HF)
Type C: Can absorb alkaline and toxic gases (such as NH3 amine)
It is used for exhaust gas purification and recovery equipment, which can absorb and recover exhaust gas from organic solvents such as benzene, alcohol, ketones, esters, ethers, alkanes, aldehydes, and gasoline. It is also used in high wind volume and low concentration coating, baking, and impregnation processes. Waste gas treatment.
Media can conduct professional testing and provide MSDS
ABS plastic frame, can be completely incinerated and discarded
Dust prevention efficiency: F7 (EN779)
Suggested final pressure loss: ≤ 450Pa
Usage environment:
Temperature range: 0-40 ° C
Maximum humidity: ≤ 70% RH
Application position of box type activated carbon filter:
1. Ideal filter for high-end healthy commercial air conditioning systems
2. The installation space is small, and there is no need for ventilation/air conditioning systems to filter dust and low concentration gas pollution simultaneously.
3. The central air conditioning and ventilation system eliminates low concentrations of organic pollutants such as sulfur dioxide and nitrogen dioxide, while also having the functions of dust removal and gas purification.
4. Air filtration in public places such as airports, hospitals (wards with respiratory diseases, etc.), and office buildings can effectively remove odors from the air while saving energy.
5. Museums, archives, libraries, and other places remove sulfur, nitrogen, and other pollutants from the air to protect their collections from damage.
6. Central control offices for chemical, petrochemical, steel, and other companies are used to protect precision equipment from corrosive gases.
7. For semiconductor and microelectronics manufacturers, remove "Aviation Molecular Pollution" (AMC) to improve product quality and protect personnel health.
8. Reduce the odor in the laboratory animal room, improve the quality of the experimental animals, and protect the air environment.
3、 How to choose a V-shaped high air volume high-efficiency filter
How to choose a high-efficiency filter and choose a suitable high-efficiency air filter? 1) High efficiency filters are used in clean rooms. The main reason for the high efficiency filter is that its efficiency detection is relatively difficult.
A、 There is a partition: the production process is simple, and the windward side is dozens of times larger than the filter end face. The partition is generally made of aluminum (pure aluminum cannot be used, usually aluminum alloy). It is best not to use paper partitions, as paper is flammable. Refuse to use paper partitions in military and medical applications (as paper is a nutritional component), and civilian use can use paper partitions. Currently, there are also some that use plastic partitions. High efficiency filters with partitions must be used in military operations, and aluminum partitions must be used.
B、 How to choose a seamless high-efficiency filter and select a suitable high-efficiency air filter
High efficiency filter, used in clean rooms. High efficiency filters are mainly difficult to detect their efficiency.
A、 There is a partition: the production process is simple, and the windward side is dozens of times larger than the filter end face. The partition is generally made of aluminum (pure aluminum cannot be used, usually aluminum alloy). It is best not to use paper partitions, as paper is flammable.

Currently, there are also some that use plastic partitions. High efficiency filters with partitions must be used in military operations, and aluminum partitions must be used.
B、 No partition: Use silk thread to separate the filter material. Compared to those with partitions, the height of the filter can be reduced for the same filtration area. Can withstand high temperatures.
Detection of high-efficiency filters:
The traditional method is to use DOP, which is an oily liquid plastic. Heat and condense it into 0.3 μ m droplets. Determine its filtering efficiency through a light scattering mirror.
Sodium ion method is used domestically to detect 99.97% of high-efficiency filters. Using scanning detection, every high-efficiency filter needs to be tested for leaks, and the scanning cost is high. However, the pass rate is low, and a 100% pass rate is impossible. The best domestic manufacturers have a scrap rate of 5%, while the poorer ones reach 40%. The foreign scrap rate is 3%. But many domestic manufacturers do not test every unit, only manufacturers such as Jianqiao and Yanjing in China conduct full testing.
Medium efficiency filter:
The most commonly used medium efficiency filters are bag filters. Generally, glass wool is also used for production. Not all tests are required. The recommended size is 24 inches by 24 inches.
Clean Room:
The filters used in cleanrooms of 10000 and 100000 levels are generally the same, but the air exchange rate and fresh air ratio are different. Such clean rooms generally rarely use fresh air systems. For cleanrooms with a capacity of 100000, using a sub high efficiency filter at the end can meet the requirements, but it is not recommended to use a sub high efficiency filter because the price difference between sub high efficiency filters and high-efficiency filters is small. However, using a sub high efficiency filter requires 20 air changes per hour, while using a high-efficiency filter only requires 10 air changes per hour. This saves initial investment and operating costs. A more economical selection.
