About the Product
The SILTBLOK SB600B is an advanced silt trap model within the SILTBLOK range, designed to deliver superior filtration and hydraulic control in surface water management systems.
The unit features a Ø600mm rotationally moulded chamber base, accommodating 225mm or 150mm twinwall main channel connections, with additional 110mm twinwall side inlets positioned at 90° and 270° from the outlet at 0°, supplied as blanked ends for optional use.
At the core of this unit lies a central barrier plate integrated with the BLOK filter, which effectively removes silt and Total Suspended Solids (TSS) before discharge. The SB600B also includes an enhanced weir section that regulates flow velocity and minimises turbulence, ensuring consistent hydraulic performance under varying conditions.
For ease of maintenance and inspection, the barrier assembly is fully removable, allowing quick access for cleaning and reinstallation. The chamber base incorporates a 515mm sump, providing generous storage capacity for silt and debris accumulation.
The SB600B is available in four standard shaft depth options, offering flexibility to suit a wide range of site requirements and installation depths.
About Siltblok
The SILTBLOK range offers a comprehensive line of silt traps and separators engineered to improve drainage system efficiency and protect downstream infrastructure.
Each model in the range incorporates Turtle Enviro’s BLOK filtration system – a precision-engineered component that forces all flow through the BLOK before discharge, effectively removing suspended solids and silt particles as fine as 30μm (0.03mm).
All SILTBLOK units, including the SB600B, are tested and quality-assured prior to dispatch, ensuring long-term reliability, ease of maintenance, and full compliance with SuDS and water management standards.
