The SBBA Manual Damper is a circular slide damper for tight closure. In the closed position, the damper is airtight and silent. Since there is no damper blade in the air stream in the open position, the damper is suitable for use in systems for dust-laden air. The damper is used for closing extraction points on machinery and in workplaces not currently in use. Available in galvanised steel construction, ranging from 80 mm to 400 mm in diameter.
The FB Duct System is used in dust collection, process ventilation, and fume extraction systems in a wide variety of industries. Nordfab FB Ducting features a flat edge on the connecting ends.
