Motorised Smoke Dampers

4 Hours Fire integrity rating

General:

The Blendair Motorised Smoke Damper Series MSD is a HEAVY DUTY damper, designed to provide efficient airflow control and to impede the spread of smoke and/or combustible products (e.g. smoke) through wall openings to other fire compartments of an air-handling system.

This range of Motorised Smoke Dampers finds its application in building construction and mining industry where ventilation, heating, cooling or air-conditioning systems are employed.

The design concept is based on an interlinked set of blades connected with a solid drive shaft using a standard pneumatic actuator or electric –electronic fail-safe spring return actuator with a fusible link incorporated into the closing mechanism and spring clip holding the blades in the closed position after closure.

Features:

  • Rugged construction
  • Tight manufacturing tolerances
  • High strength and repeatable quality of roll-formed and fully welded frame
  • Non-corrosive blade bearings
  • Stainless steel side seals.
  • Silicone tip seals
  • Suitable for masonry and dry wall mounted application
  • Adjustable mounting angles
  • Suitable for multi-module installation
  • Blendair Motorised Fire Dampers meet & are manufactured to Australian Standards 1682 and 1530 requirements
  • Smoke Spill Control Dampers

    General:

    The SSD Smoke Spill Control Damper is a safety device to control the spread of hot smoke in an emergency situation and to efficiently control the airflow in conventional air handling systems. The SSD may be a low leakage damper of an ultra-low leakage damper, which operates safely up to 200 degree C and meets AS 1668 requirements. It will be supplied with parallel blades as standard (opposed blades – optional).

    Interlocking blade edges and spring steel side seals provide the basis for reduced leakage. For ultra-low leakage the blades are fitted with high temperature silicon-rubber balloon seals that further reduce the leakage. Specially formed standard components and non-corrosive bearings conform to specifications required for high quality, low leakage, maximum rigidity and low operating torque. This allows the use of smaller or fewer actuators.

    Multiple sections are inter-connected with a solid drive shaft and provide – together with individually adjustable thermal blade linkages – a positive connection for optimum close-off sealing.

    Total damper design and close manufacturing tolerances of Blendair dampers result in LONG DAMPER LIFE, SMOOTH AND RELIABLE CONTROL and ENERGY SAVING.
