Specification and efficiency division standard of high efficiency filter in clean room:
1、 The filter is mainly used to catch particle dust and various suspended solids below 0.3um. Using superfine fiberglass paper as filter material, each set has been tested by flame absorption method, which has the characteristics of high filtering efficiency, low resistance and large dust capacity. The filter includes partition filter and non partition filter. The partition filter includes: partition filter, high temperature filter, high humidity filter, combination filter, non partition filter, liquid tank non partition filter, ultra-low resistance non partition filter, knife frame type non partition filter, and 0.1um filter efficiency.
2、 The filter material with partition filter is separated and folded by aluminum foil which is pleated by special automatic equipment with partition filter. The management of Zicheng purification on production process and strict side test ensure the product quality. Can provide a variety of materials and sizes of the frame. Two types are standard resistance type (s) and low resistance type (L). Low resistance products are suitable for places with large air volume or low resistance demand.
3、 The standard thickness of the filter with diaphragm is divided into 150, 220 and 290 mm. Because the thickness of 220mm is commonly used in China, only the standard pressure loss type is available. Because the filter material area of high air volume product is larger than that of standard air volume product, it is more suitable for places with large air volume demand. For the design of the new system, large air volume type can reduce the number of products and installation space. For the system that has been used, if the standard product is replaced by the product with large air volume, the resistance of the system can be reduced, and the advantages such as energy saving, extended product replacement cycle and reduced discard cost can be achieved.
The difference between the filter without partition and the filter with partition is as follows: 1. Whether they have actual size or nominal size is divided into actual size and nominal size, because the nominal size includes the filter with outer frame and filter material, while the actual size generally removes the outer frame, only calculating the width, height, depth and area of filter material. 2. There are similarities and differences between the partition filter and the non partition filter. The partition filter is made of ultra-fine glass fiber as filter material, rubber sheet paper, aluminum platinum as partition plate, and wood frame or aluminum alloy frame glue. It has the advantages of high filtration efficiency, low resistance and large air volume, and is widely used in various local purification equipment and clean workshop.
The non partition filter uses ultra-fine glass fiber as filter material and hot-melt adhesive as separator. It is assembled with all kinds of outer frames and has beautiful outer frames. Compared with the partition filter, it has the advantages of small volume, light weight, compact structure and reliable performance under the same air volume.
The main difference between the two is that under the same size and air volume, the resistance of the non diaphragm filter is smaller, the dust capacity will be higher, and the service life will be relatively longer. 3. The standard fold number, fold height and formula conversion of filter material answer: the fold height of filter paper with separator is generally about 30mm ~ 34mm shorter than the nominal size. The fold number is mainly determined by the tightness of separator paper and the assembly of filter paper and separator paper. The radian of separator paper is calculated according to the standard, generally 4mm, less than 4mm, there are more partitions with separator, in addition, the assembly is loose, On the contrary, the number of partitions with partition is less, while the number of folds of filter paper without partition is mainly determined by the folding height of filter paper and the tightness of filter paper.
