General Description

Jetstream is an impulse jet fan designed for the ventilation of car parks, so as both to reduce carbon monoxide levels and to assist with the extraction of smoke in the event of a fire.

Impulse fans use tunnel ventilation technology to eliminate the need for costly and bulky ductwork. Compared to ductwork systems, this may save car-parking spaces, reduce running costs and noise, and make the car park a lighter, less cluttered environment.

Scheme Design

Each car park is different and Colt will provide a scheme design to suit the exact requirements of the project. Colt Car Park Ventilation Systems include one or more of the following elements:

Natural inlet through the entrance/exit ramps/fixed ventilation louvres.
Extract by a ducted system with dual fans discharging to atmosphere.
Air distribution and mixing within the car park by a network of Cyclone Induction Fans or Jetstream Impulse Fans.

As part of a designed scheme involving detection, controls and extract units, Jetstream adds momentum to the air to thrust it towards an extract point.

In general, for day to day operation the control system monitors the carbon monoxide levels within the car park and once a set point has been reached the system increases the ventilation rates. Once a signal from the fire alarm has been received, ventilation rates are increased.
