8-Series Natural Flap Ventilator
Description

The 8-Series natural flap ventilator has been designed for use as both a smoke extraction and natural ventilation device. With options of single or twin lids and pneumatic or electrical controls, it ensures rapid extraction of smoke and hot gases during a fire.

Available with BMS integration, purpose built control panels or gas-powered struts triggered via fusible links, the 8-Series roof mounted ventilators are suitable for use on most industrial buildings. Purpose engineered control panels incorporate necessary controls relative to the types of operation required, providing remote accessibility reducing occupation health and safety risks normally associated with elevated ventilation control.

Key Features
  • Large effective throat area
  • Low profile design
  • Minimum 0.85 Coefficient of Discharge
  • Designed for BCA Fire & Smoke Requirements
  • CSIRO and NATA tested for ventilation and acoustic performance
  • Fail-safe operation
  • Pneumatic and electric options
  • Manual over-ride system

The control panel can incorporate a range of features:

  • Sensors for auto closing during inclement weather
  • Smoke detection
  • UPS battery powered back up
  • Ventilation zoning and zone coupling
  • Manual over-ride for servicing and maintenance
  • Auto timer operation to accommodate ventilation operation demands
  • Full integration into Fire Indication Panels
Scope of Use
  • Designed for use as a roof mounted natural ventilation device or automated smoke ventilator
  • Sizes available between 1200mm x 900mm and 3000mm x 1800mm
  • Typically constructed from aluminium (steel available upon request) and suitable for salt-spray zones and other corrosive environments when powdercoated appropriately
  • Multiple control options available, including electric actuators and pneumatic systems
  • Certified for use as a smoke ventilation device as part of the building fire safety system
  • The 8-Series roof ventilators can be specially designed to link up to BMS and FIP arrangements through specifically designed control panels
Limitations on Use

Installation requirements for the 8-Series ventilators vary dependent on the site wind loads, panel sizes, roof type and primary structure detailing. Ventüer provides full shop drawings for all installations which show sequencing, fixing type and sizing, flashing requirements and sealant details. Installers should make themselves fully conversant with these shop drawings prior to installation commencing.

Statement of Building Code Compliance
  • When sized correctly, the 8-Series ventilator complies with the requirements for natural ventilation of buildings under the New Zealand Building Code clause G4
  • When installed in accordance with Ventüer technical literature, shop drawings and site-specific engineering the 8-Series ventilator complies with the requirements for structure under the New Zealand Building Code clause B1
  • When installed in accordance with Ventüer technical literature and shop drawings the 8-Series Ventilator complies with the requirements around external moisture as outline in New Zealand Building Code clause E2
In-Service History

The 8-Series roof ventilators have be extensively used in theatres, public halls, stages and entertainment complexes throughout Australia and New Zealand.

Other Performance Attributes
  • Minimum 0.85 Coefficient of Discharge
  • Designed for BCA Fire & Smoke Requirements
  • CSIRO and NATA tested for ventilation and acoustic performance

Environmental Information

Effective use of passive ventilation devices such as roof top ventilators can significantly reduce the energy consumption of a building, reducing both its carbon footprint and whole of life cost.
