Detailed Photos
- Each product undergoes rigorous measurement and testing to confirm it meets customer specifications before shipment, ensuring a perfect match for your needs.
- Uncompromised Flow Efficiency
Thanks to its specially engineered V-shaped wire design, the outer openings of the screen are smaller than the inner ones, effectively minimizing the risk of clogs and ensuring seamless operation.
- Consistent Slot Precision
Our advanced CNC machine tools meticulously regulate the spacing between wires, guaranteeing uniform slot dimensions for optimal filtration.
- Robust Corrosion Defense
Crafted from top-grade Stainless Steel 304, our products boast exceptional resistance to corrosion, ensuring longevity even in harsh environments.
- Enhanced Flow CapacityThis innovative screen pipe design minimizes resistance significantly. Compared to similar-sized plastic filter elements, it offers a substantially greater flow area. This means more fluid can pass through with less effort, allowing you to either boost output or reduce the number of necessary filter elements.
- Customizable Slot GapOur screens are capable of meeting diverse filtration needs, thanks to the adjustable gap feature. Tailor the spacing between the stainless steel trapezoidal wires to suit your specific equipment and filter media requirements, ensuring perfect compatibility.
