NCA Series 700 - Multi Blade Fire Dampers

The NCA Series 700 is designed to maintain compartmentation in buildings and locations where ductwork penetrates a fire barrier, to prevent fires spreading through ductwork. With their reduced leakage design, NCA Series 700 motorised leakage rated fire dampers make them suitable for areas requiring dampers with ‘ES’ classification.

Distinctively easy to install, S700 fire dampers are surface mounted, making use of fixing lugs and a simple plate frame with factory punched fixing holes, installations require no backfilling, sealing or pattress frames. This makes them especially useful for refurbishment projects where disruption needs to be minimised.
