Wire Mesh Filter elements, their construction materials and the need of filters are discussed to describe the significance of filters in the industries

1. Filter Mesh Materials, Elements and Industrial Requirements
Heanjia’s filter media are produced from multiple layers of woven wire mesh that are diffused together to produce a
sturdy, durable and strong structure. All mesh layers are selected for a special engineering requirement such as
filtration and high strength. The mesh media is sintered in porous panels that are fabricated and welded into durable
and self-supporting filter tubes.
For the gas operations, we design surface loading filters. In this shape, the mesh layer is present on the upstream
side of the media in the normal flow way. The drainage and support mesh layers are located beneath. This structure
offers a filter with nominal pressure drop, enabling the system runner to get prolong onstream cycles. When
filtration particles come in contact with it, they are kept on the surface of filter rather in the pores as occur in the
ceramic elements. When the filter is backpulsed or washed, the enclosed particles are eliminated easily and the filter
regain its normal condition. Heanjia’s durable multiple layer design can handle the back pulsing regularly. The
sintered mesh is wear resistant and hence is avoids catalyst or unwanted particles to pass the downstream.

2. Process Media
Water
Various industrial firms need diverse kinds of process and service water for their production requirements such as
for quenching purposes, washing, rinsing and disposal, seal water for rotary seats, service water to produce the
chemical solutions. Using drinking water for these applications is very costly as a rule therefore surface water is used
for such applications. On the base of the applications and quality of water, more or less complex processing is
needed for water to receive the desired water quality. Invariably in the water processing processes, filtration of solid
particles retained in the unprocessed water is needed to ensure easy reclamation of the used water. With its
extensive range of automatic back flushing filters and inline and basket filters, Heanjia Super-Metals can fabricate
the specific process filter for the diverse areas of applications and industries.
Ballast water
Depending on the load type on ship, water is needed to offer ballast. Till now there has been risk of marine life to be
shifted to the areas resulting in affecting the ecosystem due to exchange of ballast water. Therefore ballast water
treatment systems need to be installed. With dual level systems that consist of initial pre-filtration stage and second
disinfection harmful microorganisms and germs are destroyed. The automatic back flushing filters are fit to pre-
filtration and has a guaranteed performance in various configurations.
Quenching lubricants
Uses of cooling or quenching lubricants- cooling lubricants are required in the advanced production processes for
cutting and forming with the machine apparatus and basically for the specific operations – enhancing tools life,
cutting speed, chip handle, flushing waste, limiting friction between the tool, material tool and chip.
The specific significance and stress on the specific factors are based on the specific machining procedure. Besides,
the whole quenching lubricants for metal machining are adequately tailored to different secondary needs that
creates a positive proposition for an operator:
a. Regular stability for prolong use for precise filtration
b. Outstanding corrosion resistance
c. Decrease outlay for machine damages and maintenance for regular conditioning
d. Quick disposal
In fact the excellent cooling lubricant cannot service without conditioning
To become able to receive the highest efficiency of the cooling lubricant for a prolong period, suitable filtration is
crucial. The whole contamination that penetrates into the system is eradicated from the system through filtration.
Polymer Melts
A specific region of fluid filtration is in the production and processing of plastics. Besides to the contaminants came
from the outside and resulted by the production of raw materials, the availability of gels and specks results into
further issues for the quality production.
Filtration by specific filter elements in the metallic fibers, in filtration ratings of about1 – 100 micro-m absolute is fit
in the applications. The filter elements are offered in pleated form as standard or custom elements.
Seal Gas:
Heanjia’s gas filters are made for operate in the dry gas seal units for turbo compressors. The dry gas seals of turbo
devices are extremely complicated units and are highly prone to pollution through solid particles, aerosols and
condensates. With the rotation of shafts, a small gap of about 3 micro-m is produced on the seal across which the

3. seal gas passes through. To secure these seals, the gases should be filtered suitably to make sure that seal has a
prolong life as much as feasible.
The filter elements with a coalescing action are always utilized in the whole seal gas filters. The whole elements are
made from pleated filter alloys that specify the micron rating and the contamination retention capacity and coalesce
materials that result into coalescing of the fluid phase.
Hydrogen
Hydrogen is becoming a popular alternative fuel in the automotive industry. The purity of hydrogen is crucial to
increase the service life of the fuel based automobiles. Using the gas filters particularly made by Heanjia Super-
Metals for hydrogen fuel pumps operating about 1,000 bar pressure, it is feasible to get information in the dry gas
seal filters. The filter elements comprise of pleated filter materials that specify the filtration rating and the particle
retention capacity and hence meet the needs of hydrogen fuel pumps.
Selection of filter Medium
Media Nature to be filtered: Contrast the hydraulic media the solid contamination of the process media is not
categorized following ISO. Both of these media do not need same process filtration. Nevertheless, different factors
can be recognized from which it is feasible to make the suitable choice to match the requirement of the filter.
Additionally for specific description of an application, main step for the selection of suitable filter is to categorize and
evaluate the desired medium.
Choice of filter type and filtration rating:
The choice of filter material and filtration rating is made by existing unit and the parts needed security. In specific
cases, coarse filtration is effective, while in others, although extreme filtration must be offered, complete cascade
solutions are also feasible. So, it is crucial to follow the concept, sufficiently fine mesh instead extreme fineness.

Filter Materials
The heart of a filter is its filter element that crucially describes its efficiency. Therefore Heanjia’s filters are made
from the excellent materials that meet the maximum standards considering its stability, prolong service and
cleanability.
Surface filtration- The filtration particles are mainly removed on the surface of filter. As soon as a pre-set pressure
difference is obtained or as per the constant intervals, the filer materials are eliminated and filtration process can
continue regularly or irregularly. The test filters should keep 90 to 95% of the particles bigger than specific filtration
rating
Depth filtration – The application fluid cleaned enters the filter structures, the particles are hold in the internal filter
layers. The flow resistance enhances when the particle media becomes intensely clogged that means the filter
element should be replaced. The filter keeps minimum 99% of particles more than the given filtration rating.
Heanjia’s inline filters are made for the hardest applications in process technology. They offer suitable filtration of
variety of solid contamination. Various designs and filter materials ensure the best suitability to the filtration task
and specific process media:
Temperatures up to 400oC, pressure about 1,000 bar, filtration rating from 1 – 10,000 micro-m, flow rates about
3,600 m3/h.
