Vortex Flow Control devices are devices used downstream of attenuation systems. They operate by generating a vortex flow path within the device which in turn impedes the flow.
If the scheme is pre design the attenuation storage volume can be calculated with the appropriate flow control device using this product link.
Features & Benefits:
- One piece unit, delivered ready to install into an existing chamber or headwall
- Robust, chemical resistant
- 120 year design life and guarantee
- 3mm, 304 Grade Stainless Steel to BS 1449 as standard. Other material optional.
- Coded welders approved to BS 4872 - All welded seams continuous for maximum strength.
- Removable access plate on each unit, most units easily removed for access to the downstream pipe.
-
The Units can be fitted with a by pass facility to allow system drain down from cover level should a blockage occur.
Included Accessories

Maintenance
The unit requires no routine maintenance. In the event of the blockage, it can be removed after the system has been drained down by pulling on the lifting cable located at the access.
