Hurricane™ Fire-Rated Turbine Ventilator
Combining the benefits of constant ventilation with smoke release capacity.
Traditionally smoke release ventilation involves the use of large square or rectangular roof penetrations sealed from rain penetration by a lid. The lid is normally held under pressure by compressed gas struts and controlled by a fusible link. In the event of a fire, the heat and smoke cause the link to fracture and the lid to open thereby allowing smoke to escape.
The whole principal of smoke release is to improve visibility in the premises and to improve the chance of occupants successfully escaping the smoke filled environment.
Traditional smoke release vents are expensive to install and maintain. They serve no benefit UNLESS there is a serious fire. They also fail to react instantly to smoke and fire. There is a lag until conditions around the fusible link are sufficient to break the link.
The Hurricane 900FR is a turbine ventilator which uses special thermo-plastics and high temperature bearings to comply to AS1668,1-1998: The Use of Ventilation and Air Conditioning in Buildings Part 1: Fire and Smoke Control in Multi Compartment Buildings. Section 4.8 Smoke – Spill Fan
The test requirements of AS1668.1 – (1998) 4.8.1 demanded that the H900 FR Hurricane Turbine Ventilator be subjected to:
• 120 minutes at 200°C
• 30 minutes at 300°C
and must maintain functionality at the end of the Test.
The H900FR was tested by the world renowned experts CSIRO – Manufacturing & Infrastructure Technology - and successfully achieved the following performance:
• Continued to operate for over 120 minutes at a temperature of at least 200°C
• Continued to operate for over 30 minutes at a temperature of at least 300°C
• Continued to operate for 60 minutes at a temperature of 350°C.
• Continued to operate for a further 60 minutes at a temperature of 400°C.
BENEFITS OF THE H900FR:
The H900FR offers the following major benefits to building occupants, owners and insurers:
• Constant ventilation to improve the quality and comfort of air within a working environment.
• Instant exhaust of smoke in the event of a fire – no delay waiting for the fusing of a link.
• Cheaper capital, installation and maintenance costs – there are no maintenance costs for the H900FR.
• Increasing exhaust rates as a fire progresses due to higher stack pressures.
• A coefficient of discharge at ambient in excess of 0.55
