Working principle: The cylinder shell of precision filter (also known as security filter) is generally made of stainless steel. The interior uses tubular filter elements such as melt-blown, wire-fired, pleated, titanium filter element, activated carbon filter element, etc. as filter elements according to different filter media and designs. The process selects different filter elements to meet the requirements of effluent quality. With the continuous development of the filtration industry, more and more industries and companies have applied precision filters, and more and more companies have joined the precision filter industry.

The filtration accuracy ranges from .- to inches (i.e.) in length
The above-mentioned filter element has a pressure resistance of . It can be recoiled. There are two types of interfaces: plug-in type (two types, seat type) and flat mouth type
Characteristics of pleated filter
This machine is small in size, light in weight, easy to use, has a large filtration area, low clogging rate and high filtration speed. Fast, pollution-free, good thermal stability and chemical stability.
This filter can filter out most particles, so it is widely used in fine filtration and sterilization processes.
The filter cartridge can be equipped with cores, cores, cores, cores, cores, cores, cores, cores, etc.
The length of the pleated filter element is ,,, inches
The material of the filter element is polytetraethylene, polyethylene Sulfone, nylon, polypropylene, acetate fiber
Filter pore sizes include:,,,, etc.
It is divided into hydrophobic (suitable for gas) and hydrophilic (suitable for liquid) filter elements, which can be selected according to needs.
Precision filters mainly include microporous precision filters, titanium rod filters, polyethersulfone filter elements, polytetrafluoroethylene filter elements, and microporous membrane cartridge filters.
Maintenance and repair: The core component of the precision filter is the filter element. The filter element is a fragile component that requires special protection.
If the precision filter works for a long time, it will intercept a certain amount of impurities, which will reduce the working speed, so it must be cleaned frequently and the filter element must be cleaned.
During the cleaning process, special attention should be paid to cleaning the filter element not to deform or damage it, otherwise the filtration accuracy will be reduced and the production requirements will not be met.
If the filter element is found to be deformed or damaged, it must be replaced immediately.
Some precision filter elements cannot be used repeatedly, such as bag filters, polypropylene filter elements, etc.

Note: The order of filter combination and configuration should not be reversed based on the principle of first coarse and then fine.
The actual flow rate, pressure and temperature of compressed air passing through the filter cannot exceed the values specified on the nameplate.
When installing, attention must be paid to distinguishing the inlet and outlet positions of the filter.
The filter should be installed vertically accordingly. Leave a certain height above the ground for easy replacement of filter element.
. The filter element should be replaced when one of the following situations occurs:
, the filter effect is significantly deteriorated
, the value indicated by the pressure difference exceeds. (Note: the initial pressure drop of the filter element.)
, Usage time limit: , , For filter without automatic drainer, the ball valve should be opened regularly to remove water accumulation in the filter housing. Usually no less than - times per shift
, the filter inlet temperature does not exceed ℃
, if the working pressure is lower than the standard value (.), the actual processing capacity of the filter will be corrected as follows:< br/> Inlet pressure. . . . .
