Detailed Photos
- Prior to shipment, we conduct thorough measurements and adhere to stringent testing procedures, ensuring each product meets your precise customization requirements, guaranteeing satisfaction.
- Resistant to Clogging
Thanks to its uniquely designed V-shaped wire, the outer screen surface of the hole is crafted smaller than the interior. This thoughtful design significantly reduces the risk of blockage, ensuring a seamless performance.
- Consistent Slot Precision
Our CNC machine tools meticulously regulate the spacing between wires, ensuring uniformity and precision in every gap.
- Superior Corrosion Resistance
Crafted from premium Stainless Steel 304, this product boasts remarkable resistance to corrosion, promising longevity and durability.
- Enhanced Flow CapacityThis ingeniously designed screen pipe offers minimal resistance. When compared to similar-sized plastic filter elements, it significantly expands the flow area. As a result, under identical resistance, the flow rate is substantially increased, allowing for reduced filter element usage without compromising output.
- Customizable Slot GapCatering to diverse user requirements and varying filter media, the gap of the internal wire wound screen can be tailored. Thanks to continuous welding on the equipment, the spacing between the stainless steel trapezoidal wires is adjustable to meet specific needs.
