Vortiflo Complete Vortex Flow Control Chamber 450mm
Low discharge rates, particularly from new housing developments is becoming commonplace and regularly stipulated by the Local Lead Flood Authorities (LLFA’s). So the requirement for a proven method of reducing flows from new housing sites and individual housing plots and new builds is becoming a significant part of SuDS design and overall flood management.
Specification
The Vortiflo VFCC450 features our FlowBrake mini - vortex flow control specifically designed for small housing plot attenuation, where the installation of one of our Oriflo - orifice plates, would not be suitable, particularly within adoptable installations and many localised building requirements, due to the Orifice size, which would be in most cases be below 20mm. So to offer an acceptable solution and alleviate the risk of blockage, that a small orifice could present, we have introduced the FlowBrake mini -vortex flow control into a range of chambers with diameters and pipework options to suit most applications.
Designed to facilitate such discharge flows from 0.2 to 1.5 litres per second with a design head of between 0.2 and 1.5 metres the Flowbrake Mini offers an extremely effective flow control device.
These are not supplied with a lid
