Specification

The type CFD-01 Fire and Smoke Dampers are utilised in ventilation systems to prevent the passing and spread of fire and smoke between designated divisions. The Flamgard Calidair Fire Damper is designed for bolting to steel bulkheads & decks, fixing to walls or floors or connecting directly to ductwork. All bolted connections are made via integral bolted angle flanges.
The damper has been successfully tested to global international standards highlighted above.

Dimensions

Casing

The damper casing is formed from 3.0 mm thick sheet steel into a rigid channel section to ensure proper alignment of blades and shafts. Damper Units in excess of 3000mm width or height shall be manufactured as a multiple unit assembly. Where circular dampers or dampers with width or height dimensions less than 150 mm are required, additional spigot adaptors are used which increase the damper insertion length from 300 to 400 mm.

Blades

The blades are a formed double-skin aerofoil section of 1.5 mm sheet metal which operate on the ‘Firelock’ principle creating a 3-pass labyrinth between the blades which fire cannot penetrate. Blade stops at the top and bottom of the casing and sprung side seals provide excellent low leakage characteristics. Dependent on market sector or required certification of the Damper additional patented sealing and blade materials are utilized.

Shafts

Continuous Ø 19.05 mm with blades plug welded at each end.

Product Models and Accessories

Flamgard Calidair CFD-01 Fire and Smoke Dampers are available with the following actuators:

  • Manually operated damper with a spring pack and fusible link.
  • Pneumatic spring return actuator.
  • Electronic spring return actuators with a voltage range between 24V to 430V. Including models that can be used in Ex areas and hazardous locations.
  • Electro-hydraulic actuators

Damper control systems can be mounted within an enclosure to protect them from the elements and mechanical damage.
Dampers can be fitted with a with a range of controls components for safe and hazardous areas including suitable IP ratings where required.
For available options please contact sales team for more information.

Operation Principle

Under normal operation, Fire Dampers will remain in the open position allowing for the ventilation of the associated areas. By definition, Fire Dampers must fail-safe closed to protect the rating of the fire division. This is typically achieved using a spring return system ensuring the damper closes even on loss of power.

Automatic operation in the event of a temperature rise in ductwork:

  • The fusible link will release and thus allowing the mechanical spring pack to close the dampers blades.
  • The fusible link releases and operating pressure will be cut off to the pneumatic actuator, thus causing the damper blades to close fully.
  • The fusible link releases and operating voltage will be cut off to the electric actuator, thus allowing the spring to close the damper blades fully.

Additional operations may include

  • Remote operation of the fire damper.
  • Local operation of the fire damper.
  • Remote indication of the fire dampers status.
  • Local indication of the fire dampers status.
  • Facility for automatic operation from fire or gas detection systems.
  • Facility for ‘black start’ operation.
