First, the high efficiency filter is mainly used for trapping dust and particles below 0.3um suspended solids. Ultra-fine glass fiber paper for the media, each test were confirmed by sodium flame method, with high filtration efficiency, low resistance, high dust holding capacity and other characteristics. High efficiency filter comprises a HEPA filter and non-HEPA filter, HEPA filter comprising: HEPA filters, high efficiency filter high temperature, high humidity efficient filters, no partition efficient filter comprises a modular high efficiency filters, no partition efficient filters, tank without HEPA filters, ultra-low resistance without HEPA filters, knife-free HEPA filter, ULPA 0.1 um filtration efficiency.
Second, the HEPA filter media is the use of HEPA filters special automatic device labeled wrinkled and folded aluminum foil separated by molding, Azusa-purification management of the production process and strict test to ensure that the product side quality. We can provide a variety of materials and a variety of frame sizes. Two standard resistance type (s) and low resistance type (l), the product is suitable for low wind resistance or low resistance to local needs.
Third, there is the standard thickness of the separator filter is divided into 150 mm, 220 mm, 290 mm, thickness of 220mm as domestic common specifications, so only the standard pressure loss type. Because the amount of wind Great product than the standard amount of wind filter area, it is more suitable for the needs of a large amount of wind the place. For the design of the new system, the amount of wind can reduce the amount of use of the product and the installation space. For systems already in use, if you replace the standard products with the winds of the product can reduce the resistance of the system to save energy, extend the replacement cycle of products, reduction of discards cost.
No HEPA filter and HEPA filter differences are as follows:
1. The two are not the actual size and the nominal size of the points Both actual size and the nominal size of the points, because the nominal size and frame filter comprising a filter, while the actual size is generally remove the frame, only the calculation of the filter width, height, depth and filter area.
2. There is no separator and HEPA filter similarities and differences HEPA filter is made of ultra-fine glass fiber filter, sheet of paper, aluminum foil as the partition plate with wood frame or aluminum frame and plastic made with high filtration efficiency, low resistance, large amount of wind advantages, widely used in a variety of local purification equipment and clean workshop. No HEPA filter is made of ultra-fine glass fiber filter, hot melt adhesive do the separator, with a variety of frame assembly, frame appearance, and have compared HEPA filter, in the same amount of wind, having small size, light weight, compact structure, reliable performance advantages. The main difference between the two is in the same size and the amount of wind situation, no partition efficient filter less resistance, dust holding capacity will be higher, service life will be longer.
3. The number of standard off the filter media, folding high, and the conversion formula A: There are a separator filter off higher than the height of the nominal size are generally shorter 30mm ~ 34mm about its fold number is mainly determined by the paper separator and the tightness of the filter assembly and the separator paper, paper separator radians standard computing, typically 4mm, less than 4mm, then there is every few partition on many additional assembly loose, it backfired, separators of interval number is small, the number of off without paper separator, mainly high off the filter paper, filter paper, and the tightness of the decision.
