Oriflo OFCC600

Flow Control Chamber for use with 110/160mm EN 1401 & 150/300mm twinwall pipework


The Oriflo OFCC600 is classed as a protected orifice plate – flow control chamber. 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.

Designed to be installed downstream of larger attenuation systems, ie. tank and oversized pipe systems, forming the final part of the SuDS chain.

600 diameter, single piece – 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 blockage, as well as protecting the downstream watercourse. All units feature an impact resistant, twinwall body, with a choice of inlet pipe diameters from 110mm EN 1401 to 300mm twinwall.

The standard outlet pipe is 150mm twinwall, which has a has a removable orifice plate fitted internally, however other pipework sizes are available using supplied adaptors -110/160mm EN 1401 & 225/300mm twinwall. Further inlets are available on request and with a choice of positions from 120° to 240°. The number of extra inlets will be dependant on size of pipe and orientation.
