There are several factors you might need to consider when designing the filter element. Otherwise, your filter element may not be efficient infiltration.
Some of the design considerations include;
· The Filtration Rate
It is dependent on pore sizes. The bigger the pore sizes the lower the filtration rate you will achieve and vice versa.
The specific pore sizes prevent the passing of particles beyond the specific pore sizes.
You could use an absolute or nominal micron rating.
The absolute micron rating is more specific with a filtration rate of 99%.
Nominal micron rating is less efficient at 60%.
· Pressure Drop
Pressure drop is the difference in pressure between the inlet and outlet of the filter element. There is usually a loss of pressure between the two sides of the filter element.
You should have a specification on the maximum pressure drop of the filter element that best suits your application.
· Temperature Range
Different applications will have different temperature ranges. It may be to the extreme on both ends.
Therefore, your filter element should be applied in the right temperature applications otherwise it may fail.
· Mechanical Strength
The application may expose the filter element to forces that may damage it.
Therefore, the filter element of your choice should be strong enough to resist damage.
· Filtration Area
The design should allow for enough room for filtration.
Smaller filtration are would make the filter element less efficient.
Hence the reason why the filter area is either cylindrical or plain.
The main alloys of steel that are likely to make your filter element include; 304, 304L, 316, 316L, 904L
Each of the alloy has differential characteristics as discussed below;
· Stainless steel 304SS

It has lesser carbon concentration in comparison to 304SS.
This makes it easier to weld easily. It also has got chromium ≥ 18% and nickel ≥8%.
It is non-magnetic with high resistance to corrosion and oxidation.
· Stainless Steel 316 SS
It has increased resistance to corrosion on and pitting. This is made possible due to presence of molybdenum.
Though it has similar traits as stainless steel 304, you may not opt for it in some conditions.
However, you would probably opt for it in industrial chemical manufacture of corrosive chemicals.
It is the most second utilized alloy in comparison to stainless steel 304.
· Stainless Steel 316L
This alloy has got reduced concentration level of carbon in comparison to stainless steel 316. However, you would still benefit from a similar trait as with stainless steel.
It also has higher weldability in comparison to stainless steel 316 SS.
You benefit from sintering by;
- Ability to form different shapes of the filter element

- Internal micro porosity result in 5%to 25% weight reduction
Stainless steel filter cartridge
The filter element works by creation of a physical barrier between the process fluid and the impurity.
Besides, the process fluid passes from the outside to the inside.
The outer layer is course trapping the larger impurities whereas the inner layer are finer trapping micron size impurities.
Also, the process fluid passes the filter element through high pressure. Through adhesion, the impurities stick together to form a large mass.
Cartridge filter housing
You should choose the housing for the filter element according to;
- The application parameters
- Filter element precision
- The design of the filter element
Yes, you can use either of the procedures below;

The cleaning steps include;
You should first make sure that the differential pressure is too low to cause an accident.
Put the filter element in a nitrogen furnace and heat it to 380 degrees for 2 hours
After cooling, place the element in a strong liquid and heat it to 80 degrees for 1hr.
In case of corrosion, use a cleaning agent.
You should rinse with much water until all the residues have been removed.
Blow-dry the element to remove all the water for 20 seconds or use a an oven at 50 degrees
You should use a magnifying glass to check how clean the filter element is. The magnifying glass should be 30 times stronger.
If clean, reinstall the filter element.

Stainless steel filter cartridge can last up to 2 years if utilized in the right condition.
Yes, because it is corrosion-resistant.
Some of the micron rating you could choose from include;
- 5micron rating -Most ideal in fine filtrations applications.
- 10 micron rating – This is ideal in filtration requiring medium filtrations.
- 50 micron rating – This rating is intended for pre-filtration. It is therefore used in trapping large particles or sediments before they enter the filtration element
Your filter design will be dependent on applications that would otherwise destroy polypropylene.
Such applications include;
- High pressure
- High temperature
- Chemicals that would destroy polypropylene
You should ensure that the filter element is clean. Having done that, installation should be easy as below.
- Place the filter element into the housing and fasten
- Connect the right inlet and outlet pipes and allow water in
- Close the bleeder valve
- Turn on the pump
- Open the bleeder valve and allow the excess water to pour out then close it
The pressure rating is usually specific depending on their application and the type of material used in its making.
However, the manufacturer will always indicate it to you.
The sealing configuration is the key determinant of how then sealing will be done.
Therefore, before you decide on how to seal, you need to be aware of the sealing configurations.
You cannot afford to compromise on the seal since it will have a great impact on the integrity of the seal.
Since the sealing process involves a heat process, you should leave enough allowance of the material that will be melted together to form a seal.
Therefore, you need to specify the dimensions of the Stainless Steel Sintered Filter Cartridge having put the seal into consideration.
That is during the making of the filter element.
Otherwise, you risk having a leaking filter element.
The filtration area is the surface area around the filter element where filtration takes place.
Remember, the bigger the filtration area the more the surface area for the filtration of the process fluid.
Also, the more the filtration area the higher the filtration efficiency.
A small filtration area would reduce the efficiency of your filter element.
Among the design chosen for the filter cartridge, a pleated design is the most ideal.
It creates more filtration area giving you an increased efficiency infiltration.
The diameter of the filter element also has an impact on the efficiency of the filter element.
A bigger diameter provides a bigger surface area for filtration and increased efficiency of the filter element.
Therefore, if you have an opportunity to specify the type of filter element you want from your manufacturer, you should be sure to have a high surface area.
The flow rate of the process fluid at a given pressure is also increased by having a high filtration area.
Therefore, if you want a more reliable filter element it should be of high filtration area
End configuration of stainless steel sintered filter cartridge
The end type is a representation of the type and the number of openings found in a filter element.
Most of the filter element you will find, has a double opening.
Being more specific, the type of openings you are likely to find are;
- Double open end with grommet type of seal
- Single open end with a female NPT connection
- Single open end with the male NPT connection
- Single open end with grommet type seal
- Single open end with the 222-O -ring
The end type also varies on size.
Therefore, as you choose the end type, it should be compatible with your application.
In the manufacturing arena, there are different types of filter elements.
You should therefore be able to choose a filter element that best suits your application.
Some of the filter elements that you can choose from include;
- Stainless steel mesh filter cartridge
