Oriflo OFCP300

Flow Control Chamber for use with 110mm EN 1401 pipework


The Oriflo OFCP300 is classed as an unprotected 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.

The strategic use of smaller flow control units has proven to support SuDS, in regards the overall storage and land requirement on site and from various storage systems, like smaller modular/crate attenuation systems and permeable paving.

300mm diameter, single piece – factory built units, delivered to site ready to install. Featuring a robust, impact resistant, rota moulded base with four moulded pipe spigots that accommodate 110mm EN 1401 pipe fittings. All spigots have blind ends, that can be cut off on site if required.
