Future Demands – Airports and Travel

Demand for air travel is at an all-time high and growing at an unprecedented rate. An industry forecast¹ indicates that if unconstrained, demand would grow approximately4% per annum. This rate would nearly double passenger numbers at airports by 2020 (4.2 to 7. 4 billion). In reality, growth will be constrained by capacity-issues in air space and at airports.


Two consequences of capacity restrictions will be more delayed flights and passengers having to spend more time at airports. Airport buildings are ventilated to provide breathing air for human comfort and health.

Large amounts of external air are drawn into airport buildings and this air will be heavily polluted. Airplanes are not the only source of pollution at airports. The ground traffic needed to support air operations cannot be ignored. Air quality is degraded by the operation of; push-back trucks, passenger buses, staff buses, baggage wagons, cleaning team vehicles, catering vehicles etc.

In fact, because most of these vehicles are powered by diesel engines and they operate in very close proximity to the gates, they are probably responsible for the greater proportion of pollution inside the terminals and other airport buildings.

Camfil have made a study at a major European airport and confirmed that a high proportion of the pollutants in the ventilation system fitted the profile of diesel emissions.

Pollution levels at airports may also be impacted by related but off-site activities and local non-related activities. There are very high densities of road traffic at airports and these make a significant contribution to pollution, as they do in cities.

Large amounts of outdoor air are drawn into airport buildings and it can be heavily polluted. Camfil offers an entire range of filtration products to satisfy all demands from airports. These products eliminate the nuisance of external pollutants and provide clean and comfortable breathing air for the travelling public and airport staff for human comfort and health.

Clean Air for AirportsCamfil offers products that satisfy all demands at airports to control particulate and molecular pollutants. These products also satisfy the recommendations of EN13779. Various solutions are available, depending on the extent of the problem. Molecular filtration may be applied in either the fresh air make-up or recirculation air systems. Solutions for make-up air are preferred since the principal sources of pollutant are external.

These tend to be more heavy duty and reflect the high pollutant concentrations and one-pass operation. Solutions for recirculation applications reflect lower ambient concentrations and multi-pass operation.
