Jetstream Impulse Fan
Jetstream is an induction fan designed for the ventilation of car parks and service areas, so as both to reduce levels of polluted air and to assist with the extraction of smoke in the event of a fire.
Such 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.

Features & benefits
Wide variety of product options – Two non-flanged and three flanged versions to choose from, both unidirectional and reversible. Suitable for either two speed or variable speed operation, depending on the application. Where the unit is inverter (variably) controlled, the amount of power consumed is reduced.
Certified performance - Jetstream has been exhaustively tested and certified to EN 12101-3 in accredited third party test laboratories and is CE marked. (For more details see below).
Durable construction – Jetstream is manufactured from hot dipped galvanized casing with the option of a polyester powder coating to any RAL colour.
Low maintenance jet fan ventilation system – With the additional advantage that there is no ductwork to clean.
Design service - Colt can provide a pre-order design service for jet fan ventilation units. Please contact Colt for more information relating to the application, specification, installation or servicing of Jetstream.

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 Jetstream 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 levels of pollutants within the car park and once a set point has been reached the system increases the ventilation rates. In a fire situation, once a signal from the fire alarm has been received, ventilation rates are increased.
Product details
Please see the Jetstream specification for all available options.
Certification
All versions of Jetstream and their standard isolators fully meet the F300 time/ temperature classifications of EN 12101-3 (300°C continuous operation for one hour). Test Certificates are available on request.
Noise output
CIBSE Guide Volume A: 1999, Environmental Design, sets out a recommended maximum noise level of NR55 in car parks. Colt car park systems can be designed to achieve these noise levels if required.
