Jetstream car park impulse jet fan

Jetstream is an impulse fan designed for the ventilation of car parks and underground 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.

Product information

Features and benefits

Wide variety of product options – Two non-flanged and three flanged versions to choose from, both unidirectional and reversible. The fan is 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.

Durable construction – Jetstream is manufactured from hot dipped galvanized casing with the option of a polyester powder coating to any RAL colour. Jetstream is manufactured to the ISO 9001 quality standard.

Low maintenance – With the additional advantage that there is no ductwork to clean.

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 can 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 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.

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.
