Thrust Fan Systems

Jet and Induction Thrust System

Fläkt Woods comprehensive range of fans allows individual project requirements to be met. An appropriate number of Thrust fans are selected and carefully positioned to ensure even distribution and movement of air. The controls philosophy will depend on the individual project and can range from a simple timed system, to a full pollution sensing multi-stage 6 system, with the ability to optimise efficiency and provide effective compliant solutions. The type and specification of system is determined by customer project requirements and the application of local ventilation standards.

Fläkt Woods provides systems all over the world, and can combine all forms of ventilation solutions available in the various forms of ducted, Jet Thrust or Induction thrust systems.

In case of a fire emergency, the system’s primary task is to limit smoke propagation inside the car park and direct to the closest extract points, where the contaminated air is then removed from the building.

On detecting a fire emergency signal, the Thrust Fan System is automatically switched from day-to-day mode/vent into fire mode. Jet Thrust Fan units and main extract fans are run to full design speed - reaching full speed and maximum thrust in just a matter of seconds.

Smoke is extracted by the main extract fans, whilst smoke control is maintained by the Jet Thrust Fans. Where required, the Thrust Fan System can be designed as a fully reversible system, using Jet Thrust fans with Truly Symmetrical technology, allowing the smoke to be evacuated to the nearest extract point.

Full smoke control is designed to keep escape routes clear and allow fire fighting crews easier access to the seat of the fire.

Note: Not all car parks will allow or require a full smoke control system, but Thrust Fan System can still provide a highly effective smoke clearance or fume extract only system if required.
