Controflow 300 Series Level Invert


Applications: permeable paving, filter drains and other shallow SuDS elements where water is pre-filtered.

A standard, shallow flow control chamber with an un-guarded single orifice (to specified diameter), designed to manage outflows from permeable paving or other open graded sub-base construction. Its small size and low cost make it ideal for check dams between permeable paving compartments.

The removable cap locks in position with the orifice at invert level. Three 110mm diameter inlet pipe connection stubs offer layout flexibility. Supplied with a temporary protective site cover (permanent cover and frame not included). Suitable for a maximum overall depth of 600mm (finished cover to base).

Bespoke flow control chambers can be manufactured to suit specific requirements.
