TYPE C
STANDARD FIRE DAMPER
BLADES OUT OF AIRSTREAM

GAVLANISED MILD STEEL
CASING & BLADES
 
Suitable for Spiral / Circular Duct

The AJS Type C – standard fire damper range (blades out of airstream) is designed for low to high air ductwork velocities associated with the ventilation & air conditioning industry. Manufactured by us in the UK, we provided curtain type fire damper specifically to prevent the spread of flames in fire conditions, whilst allowing maximum airflow throughout the system.
Specification / Features
  • A continuous series of 0.8mm galvanised mild steel (as standard) folded and interlocked hinged blades make up the fire curtain barrier, contained within the fully welded (airtight) damper casing of 1.2mm galvanised steel.
  • The trailing curtain blade is fixed to the head/top of the damper casing, held open via a fusible link element set to trigger @ 72ºC.
  • Two constant force stainless steel type 302 coiled band springs, exerting a pull of not less than 35n attached to the leading blade & the radius locking ramps, (profiled to the curtain/blade assembly) fitted to the base/bottom of the damper casing, facilitates the curtain/blade closure, creating both a positive lockdown of the curtain/blades & barrier to flames within the ductwork system.
