Because the filter element of the high-pressure filter mostly contains filter media such as fiberglass and filter paper.
So it cannot be used for secondary use through cleaning. For users whose use environment and maintenance are not in place, the replacement cost is relatively expensive.
(Some of our customer’s equipment are simple and do not have too many precision filter elements. So they choose stainless steel metal mesh. Which could reach minimum filtration accuracy of 5μm. It can be used for secondary cleaning, while need to pay attention to the frequency and method of cleaning.)
In addition, because the high-pressure filter is generally used to protect the precision equipment components downstream of the hydraulic system pipeline, it has extremely high requirements for filtration accuracy and efficiency.
It needs to be accurately calculated according to the system requirements, which need a long-term stability of supplier.
If you are bothered by:
》 High replacement cost of excellent filtration performance and high quality hydraulic filter elements.
》Unstable filtration performance and quality of low-cost filter elements.

Recommendations for Selecting High-pressure Filter
High-pressure filters and filter elements are necessary filter elements in hydraulic systems.
Not like suction strainer, there is no dispute about whether to continue to use.
High Pressure Filter Housing
For high pressure filter housing,
In addition to corrosion resistance, pressure resistance, air tightness and other product quality issues that need to be paid attention to,
some details in the disassemble process should also be considered.
In order to ensure the sealing and service life of filter housing.
During the installation process, the thread of the head should be lubricated, so as to prevent the thread from damage and affect the sealing performance.
Check the sealing ring before assembling and oil the O-ring.
The switching valve must be installed in right place.
High Pressure Filter Element
It’s easy if you need to replace the filter.
As long as the regulations of system comply with the original design, and has not been changed the different attributes hydraulic oil, etc.
Generally only need the brand model to replace the filter in this situation.
No need to consider other complicated factors or make changes.
Unless you have accurate records of the device usage data.
Initial pressure difference,
Even so, the scope of optimization is still small.
It may be possible to increase a certain service life by reducing the initial pressure difference.
If it is a custom filter element,
many factors must be considered.
The high-pressure filter element has strict requirements on filtration accuracy and filtration efficiency.
This means that it is not comprehensive to determine the filtration accuracy from the oil ISO cleanliness.
Usually we will judge by levels:
Identify the components most sensitive to contaminants to determine the cleanliness required by the system.
Determine the filter element installation position, filter form and pressure flow level.
According to the set pressure difference and flow level, refer to the β value curve of the filter material and based on the actual detection value of the filter accuracy.
Choose the material, length, height, diameter, etc. of the filter element. Systematic measurement of filter area.
By calculating the pressure drop of filter housing and filter element to account pressure different.
In addition, non-standard replacement filter elements are most prone to problems in the customization process.
Usually occurs in places that are easily overlooked, such as port size issues.
It must be explained to customers with a narrow installation environment and low dimensional error requirements.
Otherwise the manufacturer will ignore this when changing the abrasive tool.
