- Not easy to jam
Thanks to the innovative V-shaped wire design, the screen's external face features a smaller hole opening than the interior. This intelligent design significantly reduces the likelihood of clogging, ensuring a seamless filtration process.
- Uniform slot
Precision-engineered CNC machine tools meticulously control the gaps between wires, guaranteeing an impeccably uniform gap throughout, enhancing filtration efficiency and consistency.
- Strong corrosion resistance
Crafted from premium-grade stainless steel 304, our product boasts exceptional corrosion resistance, ensuring durability and long-lasting performance even in the harshest environments.
- Large flow rateThis sophisticated screen pipe is designed to offer minimal resistance. Compared to plastic filter elements of similar size, it dramatically expands the flow area, enabling a significantly higher flow rate under the same resistance conditions. This means you can maintain the same output while reducing the number of filter elements needed.
- Adjustable gapRecognizing that each user has distinct needs based on their specific filter equipment and media, our design allows for precise adjustment of the gap between the trapezoidal stainless steel wires. Thanks to our continuous welding process, you can customize the screen pipe to your exact requirements.
