Dual Vane Trap
The Dual Vane trap uses strategically placed vertical vanes , placed at varying heights and angles, to guide the
The Dual Vane trap is used in High Volume with medium to high velocity sites where there is minimal headloss available.
Target Pollutant Class
The Dual Vane trap is targeted at capturing the Gross Pollutant class of pollutants; however history shows they capture a varying amount of sediments and oils as well.
Water Sources / Velocity
The Dual Vane trap is suitable for treating the following water sources:
See our Deflector trap for velocities in a similiar configuration.
The Dual Vane trap is suitable for grades from less than 0.05% to to any grade. Please note while we can cater for high grades some design modification may be required.
The Dual Vane trap is suitable for treating flows from as low as a 3 month ARI up to a 100 year ARI .
We don't only treat the "first flush", we can treat the whole flow for the duration of the event.
The size of the Dual Vane Trap is dependent on the:
To give you an idea of sizing here is a sample set of configurations. The dimensions below exclude the vane footings as they are a component of the existing channel width.

Note: These figures are indicative only and do not represent the largest or smallest sizes we can treat. If you need an estimate size for your plans please contact us and we will be able to provide this information to you over the phone if you can provide some or all of the Site details.
The Dual Vane trap is generally not suited as a lidded solution, however this cannot be ruled out until the sitedetails are known.
The Dual Vane trap is a candidate for either Left or Right handed storage. the Containment Bay size is determined by various factors such as the cleaning frequency, catchment sizr and makeup.
Depending on the site and cleaning requirements the Dual Vane trap can be accessed via a ramp, ladder or internal step irons.
Although Dual Vane traps are normally cast insitu, they can be constructed using a combination of methods whichever suits the site conditions. Standard equipment and modular construction combine to make installation convienient with minimum interruption or alteration to existing conditions. Deep excavation is not a required with the Dual Vane Trap.
Cleaning of the Dual VaneTrap is dependant on the site requirements but any of the following can be used with this design of trap.
Please Note: If a trap is to be cleaned manually, there are minimal Occupation Health and Safety issues even though the caputed pollutants are dry.
