QF Damper Automatic 230VAC

Automatic QF dampers (Nordfab type SBBB, 230VAC version) open and close duct drops under electrical control on a 230VAC mains supply. Wired to switch with the machine it serves, an automatic damper means extraction air goes only where work is happening — the fan’s capacity follows production around the workshop without anyone touching a damper handle.

Galvanised steel with rolled QuickFit ends, fitted into the run with Quick Clips. Fourteen diameters are available: 80, 100, 125, 140, 150, 160, 180, 200, 225, 250, 300, 315, 350 and 400mm.

The same SBBB damper is available in other voltages — see the full QF Dampers range, including an Ex-designated 24VDC version and Energy S automatic dampers for 450–710mm duct.
