Jones & Attwood Hi-Flow Screen

This highly efficient and popular band screen provides outstanding performance that outstrips all its rivals. The Hi-Flow™  offers a remarkable 81.2% Screen Capture Ratio (SCR) efficiency in a single pass when screening at 6mm perforation with no carryover.

The Hi-Flow™ screen is available with apertures of 2, 3, 5 or 6mm, and in a range of lengths to ensure each screen can be flexibly designed to meet client requirements.

Single machine capacities are up to 3000 litres/sec, and the robust stainless-steel construction guarantees long life. The vertical lift configuration ensures these screens are ideal for sites where a compact footprint is required.

The double screening area enables higher flow rates and reduced head loss, so existing channel requirements can be accommodated.

The screen inlet diverter plates can be designed to take overflows that exceed design limits or to operate in cases of an emergency. The screens back plate can also include an opening that acts as an emergency bypass overflow.

Other features include:

  • A built-in bypass
