QF Damper Energy S Aut 230VAC

QF Energy S automatic dampers bring powered, 230VAC-controlled airflow shut-off to the largest Nordfab QuickFit diameters — the main trunk lines where closing off unused sections makes the biggest difference to fan load and energy use. Wire the damper into the system controls and big-bore branches open and close automatically with demand.

Galvanised steel with rolled QuickFit ends, joined into the duct with Quick Clips. Five large diameters are available: 450, 500, 560, 630 and 710mm.

For drops and branch lines up to 400mm, use the standard automatic SBBB 230VAC dampers; the full range of manual, regulating and diverter options is in QF Dampers.
