What are the requirements for h13 high-efficiency filter selection?
What are the requirements for h13 high-efficiency filter selection?High-efficiency filter adopts ultra-fine glass fiber paper as filter material, offset paper, an aluminum film, and other materials as split plate, glued with wooden frame aluminum alloy and become, each by the Nano-flame method of testing, has a high filtration efficiency, low resistance, large dust capacity, and other characteristics, so the use of a very wide range of that in the face of many types of filters, h13 high-efficiency filters parameters are complete, what are the specific requirements for the selection?h13 high-efficiency filter parameters can be widely used in optical electronics, LCD liquid crystal manufacturing, biomedical, precision instruments, beverage and food, PCB printing, and other industries' dust-free purification workshop air conditioning end air supply. High-efficiency and ultra-high-efficiency filters are used at the end of the clean room and can be divided into the following structural forms: high-efficiency with partition, high-efficiency without partition, and ultra-high-efficiency filters. The general principles of h13 high-efficiency filter parameters complete selection requirements: 1. Import and export diameter: in principle, the import and export diameter of the filter should not be smaller than the inlet diameter of the matching pump, generally consistent with the caliber of the inlet pipeline; 2. Nominal pressure: determine the pressure level of the filter by the highest pressure that may occur in the filter line; 3. Selection of the number of holes: the main consideration of the impurity particle size to be intercepted, based on the media process requirements, various specifications of the screen can be intercepted by the size of the particle size check the table below "filter specifications". 4. Filter material: the filter material is generally selected and connected to the same process piping material, for different service conditions can consider choosing cast iron, carbon steel, low alloy steel, or stainless steel filter; 5. Filter resistance loss calculation water filter, in general, the calculation of the rated flow rate, the pressure loss of 0.52 ~ 1.2kpa. |
