In recent years, jet fans have been used in horizontal ventilation systems, also known as impulsion or induction ventilation systems, have been established as an alternative to the traditional ones which were based on networks of ducts for extracting and supplying air. This technology is based on the longitudinal ventilation systems used in tunnels, which create a flow of air at sufficient speed to sweep the area to be ventilated.
Jet Fans and induction fans at air entry and exit points create the induction phenomenon, extracting the air and smoke from the area. This ventilation system is based on the impulsion of a small amount of air at a high speed, which homogenises the rest of the air. The system also makes it possible to keep polluting gases at low concentration levels without the need to start up the whole of the car park’s ventilation system. By starting up just the induction fans, in combination with designing zoned or staged ventilation systems and a gas detection system, it is possible reduce power consumption and noise levels, and to extend the useful life of the equipment. With impulsion ventilation, it is possible to design smoke control systems to be used when there is a fire and which satisfy the three standards enshrined in British and Belgian regulations.

These regulations form the basis on which the European Committee for Standardisation is drafting the future European Smoke Control in Car Parks Standard – EN 12101-11 and assist in:
• Extraction the smoke during and after the fire (smoke clearance)
• They facilitate the work of the fire service (fire fighting)
• They facilitate the safe evacuation of occupants (means of escape)
