General principles for efficient filter selection

General principles for efficient filter selection


High-efficiency filter - mainly used to capture particulate dust and various suspended solids below 0.5um. Ultra-fine glass fiber paper is used as the filter material, and the offset paper, aluminum film and other materials are used as the split plate, and are glued with the aluminum frame aluminum alloy. Each unit is tested by the nano-flame method and has the characteristics of high filtration efficiency, low resistance and large dust holding capacity. High-efficiency air filter can be widely used in optical air, LCD liquid crystal manufacturing, biomedical, precision instruments, beverages, PCB printing and other industries in the dust-free purification workshop air conditioning end air supply. Both high-efficiency and ultra-high-efficiency filters are used at the end of the clean room. They can be divided into: high-efficiency separators, high-efficiency separators, high-efficiency airflow, and ultra-high-efficiency filters.


General principles for filter selection:

1. Import and export routes:

In principle, the inlet and outlet diameter of the filter should not be less than the inlet diameter of the matching pump, which is generally consistent with the diameter of the inlet pipe.

2. Nominal pressure:

The pressure rating of the filter is determined by the highest pressure that may occur in the filter line.

3, the choice of the number of holes:

The main consideration is the particle size of the impurities to be intercepted, depending on the process requirements of the media process. The size of the screen that can be intercepted by various specifications of the screen can be found in the table below.

4, filter material:

The material of the filter is generally chosen to be the same as the material of the connected process pipe. For different service conditions, consider a filter made of cast iron, carbon steel, low alloy steel or stainless steel.

5, filter resistance loss calculation

Water filter, the pressure loss is 0.52~1.2kpa at the general rated flow rate

SW-CJ-1Cu double single-sided purification workbench


The horizontal one-way manifold purification workbench is a versatile local purification equipment, which is widely used in electronics, national defense, precision instruments, instruments, pharmaceuticals and other industries.


Characteristics

1, horizontal popular, quasi-closed glass damper, easy to operate.

2, using remote control switch fast two-speed control fan system to ensure that the wind speed in the work area is in an ideal state

3, using ultra-thin aluminum frame without partition high-efficiency air filter, the size of the static pressure box is reduced to a minimum, reducing the size of the cabinet shell, increasing the area of ​​the clean area
