Stainless Steel Pre-filter

Stainless steel pre-filters, also known as water purifier filter cartridges, backwash water filters, or tap water filters, are typically installed at the inlet of water pipelines. Utilizing mechanical sieving mechanisms, they provide preliminary purification of tap water. These devices are characterized by high efficiency, durability, extended service life, and cost-effectiveness, and are compatible with a wide range of air and water filtration systems. Serving as the primary physical barrier and guardian for water-using equipment at the inlet of modern water supply systems, stainless steel pre-filters play a critical role in system protection. Guangtong has long been committed to the research, development, and production of stainless steel pre-filters, consistently adhering to their core objectives of interception, protection, and lifespan extension. If you are interested in further discussing technical details or potential collaboration opportunities regarding stainless steel pre-filters, please feel free to contact us.

Stainless Steel Pre-filter Operating Principle

Filtration Stage:

 

As tap water enters the inlet of the main shut-off valve, it passes through a stainless steel filtration screen. Contaminants larger than the mesh aperture—such as sediment, insect eggs, and rust deposits—are effectively intercepted on the surface or within the pore structure of the pre-filter screen. Purified water flows through the mesh and is delivered to downstream applications.

Stainless Steel Pre-filter Operating Principle

Flushing/Drainage Stage (Approx. 30 seconds):

 

For periodic maintenance (usually every 1-3 months, or depending on water pressure monitoring), the flushing valve can be opened. The system switches to backwash mode, and the water flow direction is changed by the guide valve, flushing at high speed from the inside of the filter screen outwards, washing away impurities attached to the filter screen, and quickly discharging them through a separate drain port.

Stainless Steel Pre-filter Features and Advantages

01

Exceptional Durability Excellent Durability

The stainless steel pre-filter uses high-quality stainless steel as raw material, which has strong corrosion resistance and oxidation resistance, enabling it to operate stably in harsh environments and has a long service life.

02

Outstanding Stability

The stainless steel pre-filter demonstrates high resilience against strong water pressure shocks and water hammer effects, and its filtration performance remains stable over a long period of time.

03

High Contaminant Retention Capacity

The stainless steel pre-filter has a large filtration area, low resistance, and low pressure drop, enabling it to collect a large amount of impurities and boasting exceptional dirt-holding capability.

04

Environmental and Economic Efficiency

The pre-filter features minimal instantaneous water discharge during backwashing cycles and low energy consumption, aligning with international standards for environmental sustainability.

05

Easy Cleaning

Equipped with an automatic backwash function, the stainless steel pre-filter efficiently eliminates retained contaminants to ensure water purity, reducing the need for frequent replacements and lowering operational costs.

Stainless Steel Pre-filter Quality Control System

Raw Material Control

Raw Material Control

Metal raw materials are subjected to chemical and physical performance testing to ensure only qualified materials enter the workshop for production.

In-process Inspection

In-process Inspection

All molds and equipment undergo calibration to achieve minimal tolerances, ensuring compliance with order specifications and industry standards. Additionally, sampling inspections are conducted throughout the manufacturing process.

Finished Product Inspection

Finished Product Inspection

All metal filters undergo performance testing prior to warehousing and packaging. Foam tests can be performed upon customer request to verify the sealing integrity of welds and joints. Products that pass inspection are stored in designated areas awaiting packaging and shipment.

Document Traceability

Document Traceability

Guangtong's metal filter components use a unique code tracking document from the beginning of raw material entry to provide data support, ensuring traceability and order transparency at every stage, effectively reducing downtime of metal filter equipment and avoiding quality issues.

Packaging

Packaging

After multiple layers of inspection, metal filter elements are packaged using plastic film and plywood cases to prevent damage during transportation.

Shipping

Shipping

We collaborate with reliable freight forwarders to closely monitor logistics information for each shipment. Real-time tracking of delivery status ensures the safe and efficient arrival of every batch of metal filter elements, which remains our long-standing operational principle.

Customer Testimonials

Alexandra

US market

Our beverage factory has strict requirements for food safety, Guangtong customized a stainless steel pleated filter element for our filtration equipment, which exceeded our expectations completely. The R&D team of Guangtong had detailed communication with us to confirm the details on the drawings (including dimensions, material, filtration accuracy, etc.). This stainless steel pleated filter element fully meets our requirements. Its surface is polished to a mirror finish (roughness of 0.4 microns), and there are no installation problems. During use, it can effectively remove impurities from the juice while retaining the original flavor. The 3l6L stainless steel material enables it to withstand repeated high-temperature sterilization and maintain stable filtration accuracy, with a filtration efficiency of 99.6%, this has significantly enhanced our production efficiency and enabled us to successfully pass the FDA inspection. The rapid response mechanism, the professional R&D team, and the rigorous quality control have facilitated our subsequent collaboration and enabled us to become long-term partners.

Oliver Fuchs

European market

As a chemical enterprise, we established contact with Guangtong this year and inquired about a metal sintered filter element. Guangtong provided a complete ISO certificate and customized a sintered filter with high temperature tolerance up to 200 degrees Celsius based on our filter medium drawings. This sintered filter has been in use for 6 months and has not shown any leakage. Compared with previous sintered filter suppliers, its maintenance cost has been reduced by 40%. For an enterprise with customization needs like ours, we highly recommend it!
