Controflow 300 Series Stepped Invert Protected Orifice

SUDS01101

Applications - permeable paving, shallow underground storage structures or where haunching or other underground obstruction prevents the use of the shallow 300 series level invert chamber.

A small flow control chamber with a 110mm diameter inlet and protected orifice located at the base of a removable flow control tube. The flow control tube allows access to a deeper chamber where pipe inlet depth is obstructed by other construction factors like kerb haunching or existing pipe work.

The removable flow control tube is perforated to protect the orifice in the base of the tube. The handle to the tube provides access by hand for inspection and cleaning. This product does not incorporate an internal overflow (if required, use Controflow 500 Series Universal).
