Product Insights & Specifications

* Working Principle: Water flows over an acceleration plate at high velocity; the Coanda effect causes clean water to adhere to and pass through tilted wedge wires, while debris and sediment are "sheared" off and carried downstream by momentum. Coandaintakes Filsonfilter

* Material Standards: High-grade SS304 is the industry standard for freshwater, while SS316L or Duplex stainless steel is increasingly preferred for corrosive or brackish environments. Coandaintakes Pfmscreen

* Technical Benchmarks: Typical slot widths range from 0.5 mm to 1.5 mm for fish protection and debris exclusion, with a standard flow capacity of approximately 140 L/s per meter of weir width. Coandaintakes Filsonfilter

Market Trends & Industry Outlook (2024–2026)
