Car Park Ventilation Systems

Car Park Ventilation systems are critical in preventing the build up of toxic fumes and flammable gases from motor exhausts aswell as clearing smoke in the event of a fire. 

Car Park Ventilation can be achieved with a number of different solutions. React 4 Group can provide the following:

Natural Ventilation

Mechanical Extract

Hybrid Naturally assisted 

Using the latest technology and computer software all systems are designed to the highest standard meeting the most stringent criteria.

Mechanical Systems - Jet Fans

These car park ventilation systems are characterised by jet fans replacing the traditional ductwork. They drive fumes or smoke towards extract fans, keep pollution within acceptable levels, and clear smoke.

Higher System Performance

By controlling the air supply with Thrust fans a full smoke control design can be made – something just not possible with a conventional ducted extract system. In an emergency situation, full fan extract rate can be reached in as little as 20 seconds allowing immediate response to the situation. Full smoke control can be designed into the system, which can encompass fully reversible Jet and extract fans if required.


Lower Installation and Running Costs

Installation costs are normally lower with a Thrust Fan System, compared to a ducted system. Installation is simpler saving on labour costs, dependant on the size and form of the car park. There are other hidden savings too. With no ductwork, other services such as, cables, gas and water supplies, soil pipes and so on, can be routed straight across the ceiling line, without having to divert around extract ductwork or hangers. Access for routine maintenance is easy, and of course, there are no distribution ducts and dampers to be cleaned and inspected.
