Junhe manufactures perforated plate filter baskets for industrial liquid filtration, solid-liquid separation, process equipment protection and impurity removal applications.
A perforated filter basket uses a rigid plate or basket structure with precisely formed openings to intercept solid particles while allowing liquids or other process media to pass through. Compared with unsupported fine mesh, the perforated structure provides mechanical support and dimensional stability, making it suitable for filtration systems that require a strong, reusable filter element.
Junhe supplies standard and custom perforated filter baskets for water treatment, chemical processing, food and beverage production, pharmaceutical processes, automotive systems and other industrial applications.
Basket dimensions, perforation size, hole pattern, material, flange or connection structure and optional filter mesh lining can be customized according to filtration requirements, equipment dimensions and operating conditions.
For broader filtration media and screening products, see our Filter Mesh range.
A perforated plate filter basket separates particles from a flowing medium through openings distributed across the basket wall.
During operation:
The process medium enters or passes through the filter basket.
Particles larger than the selected opening or filtration layer are retained.
The filtered liquid continues through the perforations.
Collected contaminants can be removed when the basket is cleaned or replaced.
The perforated plate provides the structural framework of the filter element. Depending on the required filtration accuracy, it may be used alone for coarse filtration or combined with a finer wire mesh layer for more precise particle interception.
This distinction is important when specifying a filter basket. Perforation size and filtration rating are not always the same parameter. A basket requiring fine filtration may need both a perforated support structure and an appropriately selected filter mesh.
Perforated plate filter baskets can be designed in different forms according to filtration equipment and installation requirements.
A standard perforated basket uses uniformly distributed openings across the basket body.
It is suitable for applications where larger contaminants need to be removed while maintaining relatively unrestricted flow.
For applications requiring finer particle retention, a perforated plate can serve as the structural support for an additional filter mesh layer.
This design combines the mechanical strength of perforated metal with the smaller openings of fine wire mesh.
It can be considered for applications where filtration accuracy is smaller than the practical perforation size of the supporting plate.
Industrial filtration equipment does not always use standard cylindrical or rectangular dimensions.
Junhe can produce custom basket structures according to drawings, equipment dimensions and installation requirements, including different:
Diameters
Heights
Basket shapes
Flanges
Handles
Openings
Support structures
Connection configurations
The performance of a filter basket depends on several parameters working together rather than on filtration accuracy alone.
| Specification | What Buyers Should Consider |
|---|---|
| Basket Material | Selected according to corrosion, temperature, fluid and hygiene requirements |
| Perforation Size | Determines which larger particles can pass through the supporting plate |
| Filtration Rating | May depend on perforation size or an additional mesh lining |
| Hole Shape | Round, square, rectangular, elongated or other patterns depending on design |
| Open Area | Affects flow capacity and pressure drop |
| Plate Thickness | Influences structural rigidity and mechanical strength |
| Basket Diameter | Must match the filtration equipment or housing |
| Basket Length / Height | Affects filtration area and dirt-holding capacity |
| Connection Structure | Flange, rim, handle or other installation configuration |
| Operating Conditions | Flow rate, pressure, temperature and process medium should be confirmed |
| Cleaning Method | Reusable baskets should be designed for practical removal and maintenance |
Final specifications should therefore be based on the actual filtration system rather than selecting a basket only by nominal micron rating.
The perforation pattern influences open area, flow characteristics, mechanical strength and cleaning performance.
Common hole configurations can include:
Round perforations are widely used because they provide a practical balance between structural strength, open area and manufacturability.
They are suitable for many general industrial filtration and separation applications.
Square and rectangular perforations can provide different open-area characteristics and may be selected where the process requires a specific particle shape, flow pattern or structural layout.
Elongated or slotted holes may be considered for applications where increased open area or directional screening is required.
The correct perforation pattern should be selected according to particle size, required flow and structural conditions rather than appearance alone.
Material selection should be based on the process medium and working environment.
Stainless steel is commonly used for industrial filtration where corrosion resistance, cleanability and repeated use are important.
It may be suitable for water treatment, chemical processing, food-related equipment and other demanding filtration applications, depending on the stainless steel grade and process conditions.
Other metal materials may be considered according to mechanical strength, corrosion environment, cost and equipment design.
Buyers should provide information about the fluid or process medium when requesting a material recommendation.
For projects that require perforated sheet rather than a finished basket assembly, see our Perforated Metal Mesh products.
Perforated filter baskets can be used during water-treatment pretreatment to intercept sediment, debris and suspended solids before downstream filtration or treatment equipment.
The required opening size depends on the contaminant profile and the following treatment stage.
Chemical production systems may use filter baskets to separate solids, catalyst particles or process contaminants from liquid streams.
Material compatibility and corrosion resistance should be confirmed according to the chemicals being processed.
Filter baskets can be used for the removal of larger solids, residues and process particles from liquids.
Where food-contact applications are involved, material, surface condition, cleanability and hygienic design requirements should be confirmed before production.
Industrial process systems may require customized filter baskets for reaction vessels, pipelines, tanks or other equipment.
The basket dimensions, filtration level and material should be matched to the equipment and process conditions.
Filter baskets may also be used to protect pumps, lubrication systems, fuel systems and other mechanical equipment from larger contaminants.
The appropriate structure depends on fluid viscosity, particle size, flow requirement and operating pressure.
One of the main functions of a basket filter is to prevent unwanted solids from reaching downstream pumps, valves, nozzles or process equipment.
Using the correct filtration level can help reduce blockage and protect equipment while maintaining the required flow.
First determine the smallest particle size that needs to be retained.
Do not assume that the perforation diameter alone represents the final filtration rating. Fine filtration may require an additional mesh layer.
Provide information about whether the basket will filter:
Water
Oil
Fuel
Chemical liquids
Food or beverage products
Process fluids
Other media
This information is important when selecting material and structure.
Higher flow requirements generally require sufficient filtration area and open area to avoid excessive resistance.
Basket diameter, length, perforation pattern and open area should therefore be considered together.
Pressure and temperature can affect material choice, plate thickness, connection structure and overall basket strength.
Actual operating conditions should be supplied for industrial applications.
The filter basket needs to fit the housing, vessel, pipeline or processing equipment.
Important dimensions may include:
Outer diameter
Inner diameter where applicable
Basket length
Flange dimensions
Rim structure
Installation depth
Handle dimensions
Drawings are recommended for replacement or non-standard filter baskets.
For larger-particle interception, a perforated plate basket may be sufficient.
For smaller particles, a wire mesh lining or multilayer filtration structure may be required.
Reusable filter baskets should be easy to remove, inspect and clean.
The basket structure should therefore consider both filtration performance and actual maintenance procedures.
Junhe provides customized perforated plate filter baskets according to drawings, samples and filtration requirements.
Customization can include:
Basket diameter and length
Custom shapes
Perforation size
Hole shape and pattern
Plate thickness
Material selection

Through our OEM and ODM services, filter baskets can be developed for both replacement requirements and new filtration equipment.
For custom projects, buyers should provide the filtration rating, medium, flow requirement, operating pressure and temperature, basket dimensions, material preference and quantity whenever available.
Contact Junhe to discuss your perforated filter basket specifications.
A perforated plate filter basket is a rigid filtration component manufactured with controlled openings that allow the process medium to pass while retaining larger solid contaminants.
A perforated plate provides greater structural rigidity but generally has larger practical openings. Wire mesh can provide finer filtration. For some applications, perforated metal is therefore used as the support structure with a finer mesh layer added inside or outside.
Yes, but the required structure depends on the target filtration rating. Where the required particle size is smaller than the practical perforation size of the plate, a fine wire mesh lining may be added.
Provide the basket dimensions, material, perforation or filtration rating, process medium, operating pressure, temperature, flow requirement, connection structure, quantity and drawings if available.
Yes. Perforation size, hole pattern, basket diameter, length, material and connection structure can be customized according to equipment and filtration requirements.
The choice depends on the smallest contaminant that needs to be removed and the downstream equipment that must be protected. Coarse filtration can often use perforated metal alone, while finer filtration may require an additional mesh layer.
