Oriflo Protected Flow Control 500mm Ø Chamber C Series
The ORIFLO C series is a protected orifice plate unit, designed to support SuDS management and the sewer infrastructure as part of a designed attenuation system, helping prevent flooding by controlling the flow into the main sewer.
Integrally, all of our OFCC models are fitted with our unique SILTBLOK barrier, this barrier protects the orifice plate from any potential blockages from silt or debris, as well as protecting the downstream watercourse. The SILTBLOK barrier has a debris basket attached to the inlet side, which collects any silt and debris. The barrier with basket attachment can be simply removed for emptying and maintenance.
Factory built units, delivered to site ready to install. Integrally there is a unique SILTBLOK filter and debris barrier. The barrier protects the orifice plate from being blocked, as well as protecting the downstream watercourse. All units feature an impact resistant, twinwall body, with a choice of main pipework diameters from 110mm EN 1401 to 450mm twinwall, with extra inlets available on request.
Applications: Typically installed downstream of larger attenuation tank and oversized pipe systems, forming the final part of the SuDS system prior to discharge to sewer.
