What are the common classifications of different filters?High Efficiency FilterWhat are the factors that influence the price?

With the filter is widely used in all aspects of society, to adapt to the needs of each place for a variety of designs, according to the different filtration efficiency of the primary and secondary effects,High Efficiency FilterWhile filters can be categorized according to the place of application and form, they can also be categorized in other ways.

First, there are three styles of primary filters: folding primary filter, plate primary filter and bag primary filter, with paper frame, aluminum frame and galvanized frame as frame materials, and non-woven fabrics, nylon mesh, activated carbon filter material and metal pore mesh as filter materials, which are mainly used for filtering dust particles above 5um.

Second, the medium-effect filter has bag-type medium-effect filter and plate-type medium-effect filter, combined medium-effect filter and so on. Intermediate filters are widely used in the intermediate filtration of air-conditioning systems, mainly for filtering dust particles of 1um~5um, with the advantages of small resistance and large air volume.

Third, the high-efficiency filter is mainly divided into partitioned high-efficiency filter and non-partitioned high-efficiency filter, box-type high-efficiency filter, cartridge-type high-efficiency filter and so on. High-efficiency filters are mainly used to capture particles of dust and various suspended matters below 0.3um, with a filtration efficiency of 99.99% 0.3um. It adopts ultra-fine glass fiber paper as the filter material, offset paper, aluminum film and other materials as the dividing plate, and is glued with aluminum alloy.

High efficiency filter price cost main factors:

A. Filter material: ultra-fine glass fiber paper is used as filter material, and most of the filter material is H13 glass fiber filter paper or H14 glass fiber filter paper, and different filter materials directly affect the price and cost of high-efficiency filters. Each unit has been tested by the Nano-flame method, featuring high filtration efficiency, low resistance and large dust capacity.

B. The outer frame of the high-efficiency filter is usually aluminum or stainless steel frame, etc. The choice of these frames also determines the rising or decreasing cost, which determines the price of the high-efficiency filter.
