• Car park

Mechanically vented carparks are designed to operate with either traditional ducted or modern impulse ventilation systems.

Our car park fans operate on well-proven tunnel ventilation principles, producing a high velocity jet that, as it diffuses, imparts thrust to the surrounding air through mixing and entrainment.

Fans should be carefully positioned to direct the airflow towards the main extract fan’s intake points. We carefully size our main supply and extract fans to provide the required flow rates. In systems with reduced requirement for ducting within the car park area, this allows for smaller exhaust and supply fans to be selected.

Elta Fans’ emergency smoke spill fans operate as part of the main extract system to safeguard occupants by removing pollutants and, in the event of a fire, as dedicated fans for emergency clearance to overcome hazardous fire, smoke and fume conditions.
