Zhejiang V-shaped high-efficiency filter manufacturer

Zhejiang V-shaped high-efficiency filter manufacturerLike high-efficiency filters with partitions, they are mainly used in industries such as microelectronics, precision instruments and meters, medical and health, biotechnology, pharmaceuticals, and food, as well as in various cleanrooms, clean tunnels, high-efficiency air supply outlets, purification workbenches, air showers, and other purification equipment for final air filtration. The filtration efficiency for particles ≥ 0.3 μ m is above 99.99%. Both high-efficiency and ultra high efficiency filters without partitions are used at the end of the clean room. The outer frame can be selected from aluminum alloy frame, galvanized frame, wooden frame, or stainless steel frame.

Zhejiang V-shaped high-efficiency filter manufacturerStructural classification:

High efficiency filters are mainly divided by structure into: partitioned high-efficiency filters, non partitioned high-efficiency filters, and combined high-efficiency filters.

Introduction to high-efficiency filters with partitions:

The high-efficiency filter with a partition adopts a partition design, and the corrugated partition can maintain the spacing between the pleats, making use of the filter material under low resistance. The filter material is folded 180 folds on both sides to form a wedge-shaped fold layer. When the filter material is bent, there are two indentations, which make it open into a wedge-shaped box shaped fold layer at the end of the partition. The wedge-shaped box shaped fold layer can prevent damage to the filter material. In corrosive environments, ethylene coated separators can be used to capture 0.3umr particles with an efficiency of 99.99% -99.999%. Thickness series: 80, 120, 150, 220, 292, etc;

Introduction to high-efficiency filters without partitions

The high-efficiency filter without partitions uses glass fiber filter paper as the filtering material, aluminum alloy (galvanized sheet) as the outer frame, hot melt adhesive as the separator, and polyurethane as the sealant. The high-efficiency filter without partition is composed of waterproof and flame-retardant glass fiber filter paper or PP high-efficiency filter material. A spray coated protective net can be installed on the air outlet surface to protect the filter paper from damage. The lightweight and compact design makes it easy to install in open enclosures, fan filter units, and cleanrooms. The outer frame is made of aluminum alloy profiles, stainless steel plates, or galvanized plates, sealed with environmentally friendly polyurethane sealant. The filtration efficiency is 99.95% -99.999995% (H10-U17).

Introduction to Combined High Efficiency Filters

The composite high-efficiency filter without partitions is made of glass fiber filter paper and ultra-fine polypropylene filter paper, with a plastic outer frame, hot melt adhesive as the separator, and polyurethane as the sealant. Its efficiency is (F6-H14) medium high efficiency.

Characteristics of combined high-efficiency filter: large filtration area, low resistance, long service life. Can be incinerated for environmental protection.

Note on high-efficiency filter without partition:

(1) Installation of high-efficiency filter:

Due to the brittleness of fiberglass paper, the first consideration in use and installation is to avoid contact with sharp objects and repeated rubbing. Secondly, fiberglass paper should be used with minimal contact with water or other corrosive liquids to avoid affecting its normal use. Require clean workshops to have good cleaning equipment. Again, the reasonable use of coarse, medium, and high-efficiency filters ensures that each filter does not bear excessive dust loads. Before installation, conduct a visual inspection to check for any damage to the appearance of the filter paper and filter. After installation, inspect the sealing condition and conduct strict leak detection.

(2) Common knowledge of high-efficiency filter filtration

For different particle sizes, the efficiency of high-efficiency filters can reach over 99.999999 (overseas). Some people always associate the efficiency level of the filter with the level of the clean room, as if using as many 9 ultra high efficiency filters can achieve a cleanliness level of 100 or even 10. Actually, this is a misconception. Efficient filters are the core of the system, but they are not a condition for ensuring cleanliness. The efficiency of the high-efficiency filter meeting the requirements is only one of the necessary conditions, and it is also an easily achievable condition. To achieve the corresponding level of a clean room, there should be many necessary conditions, such as air speed, air exchange rate, door and window sealing, and control of personnel entering and leaving the clean room. Only when all these aspects meet the standards can the cleanliness requirements of the clean room be guaranteed.
