Stainless steel high precision filter housing

Stainless steel high precision filter housing  

     Cartridge filter, also known as security filters, generally set before the pressure vessel to remove the tiny particles whose turbidity above 1 degree, to meet the requirements of  the follow-up process of water; sometimes, it is also set at the end of the entire water system to prevent small particles (such as broken resin) into the finished water.

High precision filter Working Principle

     Cartridge filter, also known as security filter. The shell is made of high quality stainless steel, filter using molded filter, The liquid went through filter under pressure, residue left on the filter, and the filtrate outflow through the filter can effectively remove impurities in the water, sediment and suspended solids, bacteria.
     Molded filters are: cloth, screen, filter, sintered filter tube, wound filter, melt-blown filter, micro-porous filter and multi-function filter. 
     Due to different filter, the filter pore size is not the same. Precision filter is between the sand filter (coarse) and a filter between ultra-filtration, filter pore size generally between 0.01-120um.For the same form of filter,it is divided into different models by their dimensions.

Commonly used wound filter and meltblown filter 

     Wound filter (also known as honeycomb filter), there are two types: one is polyp

ropylene fiber - polypropylene skeleton filtration, the maximum temperature 60 ℃; the other is cotton fiber - stainless steel frame filter, the maximum temperature 120 ℃. 

    Raw material of meltblown filter is polypropylene, the maximum operating temperature is 60 ℃. 

    Sophisticated filters can remove suspended solids, colloidal substances and some fine particulate matter and so on.

High precision filte Composition

     Cartridge filter is mainly composed by the 

filter housings, filter cartridges and other components, and the filter housings materials is mostly made of R304 stainless steel, if it’s used in the acid and other special occasions,it will be made by R316 stainless steel. It an be divided into the flange and clamp, and flanged housing is mainly used in the occasion of larger flow filtration. The filter is mainly made by PP cotton, it can also be made by wound filter or activated carbon filter on some occasions. The number of filter may vary from 1 to dozens, primarily be determined from the water flow rate.

High precision filte Application

1, Food industry:fine filter of space water, mineral water,beverages, liquor clarification and filtration process. 
2, Pharmaceutical industry: sterile water, oral, infusion and injection water treatment. 
3, Electronics industry: water preparation semiconductors, instruments, picture tubes and other production plants, wash water filtration bar.

Types of High precision filter

High precision filter Installation

High precision filte Structure

     This device is cylindrical steel with elliptical head down, the body with a perforated plate inside a filter element into the filter and the water column into two parts, with a certain degree of heat resistance. Filtering accuracy of 10um, 5um, 1um and so on. Small device is made of stainless steel.

How to choose the correct model

    Ultrafilter often disposed after the pressure filter for removing fine particles in a liquid, the water in order to meet the requirements of the subsequent process. Sometimes a full water treatment system is also set in the end, to prevent small particles from entering the finished water. 

The filter has a honeycomb core common and meltblown filter. Filter precision micrometer (um) dollars, are the following specifications: 0.5 0.8 123,451,020,305,075 100 to be selected according to different requirements.

High precision filte Attention

1, You should prevent pressure surges, prohibit reverse pressurization. 
2, when the pressure difference between upstream and downstream flow is significantly larger than 0.05Mpa or decline, you should consider replacing the filter.

Small-flow High precision filter with clampopening.

1, the body open the way for quick opening hoop (or quick opening flange), to facilitate the efficient filter replacement and cleaning. 
2, compact structure, small size, improved V-shaped hoop quick opening, the stress tests, the pressure without any distortion and leakage after 0.6MPA.
1,Cartridge filter uses stainless steel as material,with electrochemical polishing or matte finishing out appearance. Also PP is available.
