Customizable strainer filter for Your Needs

some description about product

Strainer filter is a type of filtration device used to remove solid particles from fluids or gases. It consists of a perforated or mesh screen that allows the passage of the desired medium while capturing and retaining the solids.

Simplex strainer has a single straining element and is typically used in applications where temporary shutdowns for cleaning or maintenance can be tolerated.

The primary function of a strainer filter is to protect downstream equipment, such as pumps, valves, nozzles, and other sensitive components, from damage caused by particles or debris. It helps maintain the efficiency and longevity of the system by preventing clogging, reducing wear and tear, and ensuring smooth operation.

Strainer filters can be found in various industries and applications, including water treatment, oil and gas, chemical processing, food and beverage, pharmaceuticals, and HVAC systems. They are commonly used for filtration tasks where the particles to be removed are relatively larger in size compared to fine filtration applications.

Proper installation, routine inspection, and maintenance are essential for optimal performance of strainer filters. Regular cleaning or replacement of the straining element is necessary to prevent clogging and maintain efficient filtration.

The construction of a wedge wire filter consists of several parallel V-shaped wires, also known as wedge wire, that are welded to support rods.

perforated strainer

Perforated strainer

The main component of a perforated strainer is a plate or screen made of metal, typically stainless steel, that features a pattern of uniformly spaced holes or perforations.



Y-strainers are a type of strainer filter that derives its name from its Y-shaped body design.

They are commonly used in pipelines to remove solid particles and debris from flowing liquids or gases.

Y-shaped body of the strainer contains a straining element, such as a mesh screen or perforated plate, positioned inside the branch of the Y. The fluid or gas flows through the inlet and enters the Y-strainer, where the straining element captures the solid particles while allowing the desired medium to pass through the outlet.

Y-strainers offer several advantages. Firstly, they provide an effective and economical solution for protecting downstream equipment, such as pumps, valves, and meters, from potential damage caused by debris or particles. They help to maintain the efficiency and longevity of the system by preventing clogging and reducing maintenance requirements.

Construction of strainer filter

Construction of strainer filter

The construction of a strainer filter typically consists of a strainer body, components such as inlet and outlet connections, a straining element (such as wire mesh or perforated plate), and a cover or closure mechanism.

Strainer body is designed to withstand the operating conditions and is typically equipped with a removable or cleanable straining element to capture solid particles. The inlet and outlet connections allow for the strainer filter to be installed in the pipeline or process system. The cover or closure mechanism ensures proper sealing and easy access for maintenance and cleaning of the strainer element.

Strainer filter working principle

Strainer filter working principle

The working principle of a strainer filter is based on the concept of mechanical filtration, which involves the removal of solid particles or debris from a fluid or gas stream. Filter acts as a barrier that allows the desired medium to pass through while capturing and retaining solid particles.

When the fluid or gas flows through the strainer filter, it encounters the straining element, which is typically a fine mesh or perforated plate. The straining element has openings that are smaller than the particles to be removed, allowing the fluid or gas to pass through while blocking the solid particles.

As the fluid or gas passes through the straining element, solid particles larger than the openings in the straining element are trapped on its surface or within the openings. This prevents the particles from continuing downstream and protects equipment, valves, pumps, or other downstream components from potential damage or clogging.


Most frequent questions and answers

Strainer filter mesh refers to the fine mesh material used in strainer filters to capture and retain solid particles. It is typically made of materials such as stainless steel, brass, or synthetic fibers. The mesh is characterized by its mesh size, which defines the number of openings per linear inch or millimeter. The smaller the mesh size, the finer the particles that can be captured.


Strainer filter mesh is selected based on the desired level of filtration and the size of the particles to be removed. It plays a crucial role in the filtration process of strainer filters by effectively trapping solid particles while allowing the desired medium to pass through.

Inline water strainer filter works by allowing water to flow through a straining element, typically a fine mesh or screen, that captures solid particles and debris.


Strainer is installed in the water line, and as water passes through, the straining element traps larger particles while allowing clean water to continue flowing. The captured particles are prevented from entering downstream equipment or appliances, protecting them from damage or clogging. Regular maintenance and cleaning of the strainer are necessary to ensure optimal filtration performance.
