Hepa Filter Manual

Hepa filter is mainly used to capture below 0.5 um particles of dust and all kinds of suspended solids, as various filtration system at the end of the filter.Use made of super fine glass fiber paper, glue, materials such as aluminum foil folding partition board, the new type of polyurethane sealant seal, and galvanized sheet, stainless steel plate, aluminum alloy profile as the outer frame is made.

Hepa filter is mainly used to capture particles of dust and all kinds of suspended solids under 0.5 um.Use made of super fine glass fiber paper, offset paper, aluminum membrane materials, such as partition board, with wooden frame aluminum alloy agglutination.

Each are flame method test, filter with high efficiency, low resistance and capacitance of large amount of dust, etc.High efficiency air filter can be widely used in optical electron, LCD manufacturing, biological medicine, precision instruments, drinks, food, PCB printing industry such as dust-free purification workshop air terminal air supply.Efficient and highly efficient filters are used in the clean room terminal, in the form of the structure can be divided into: a hepa filter, hepa filter without separators, big air volume high efficiency filter, super high efficiency filter, etc

The general principles of the selection
1, import and export size:
In principle, the import and export of the filter size should not be less than the import of matching pump size, generally consistent with imported pipe diameter.
2, nominal pressure:
According to the possible highest filter line pressure to determine the filter pressure rating.
3, the number of hole mesh:
Main consideration to intercept the impurities particle size, on the basis of medium process technological requirements.All kinds of wire mesh can intercept the particle size of the check table below "mesh specifications".
4, filter material:
Filter material selection and the general connection of process piping material is the same, for different service conditions can consider to choose cast iron, carbon steel, low alloy steel or stainless steel filter.
5, filter resistance losses calculation
Water filter, in the general calculation under the rated flow rate, pressure loss of 0.52 ~ 1.2 kpa

Technical characteristics
1, simple and reasonable structure design, cover an area of an area small, installation, disassembly is simple;
2, the cleaning time is short, small pressure loss, less water consumption;
3, filtering, high precision, suitable for all kinds of water filter;
4, the intelligent control system, can realize remote control;
5, set up with the motor overload protection device, safe and reliable;
6, in cleaning sewage can uninterrupted water supply;
7, the equipment service life is long, no need for replacement.
