Airport Buses are a common means of transferring passengers from the planes to the Arrival Gates. Suvarnabhumi Airport Concourse building is equipped two Arrival Bus Gates, one for Domestic flights and one for International flights. Due to strong inward draft from the runway into these Bus Gates, hot air from outside could enter the Concourse building and raise interior temperature to the point of discomfort for passengers.
Suvarnabhumi Airport implemented X-PER Heavy Duty Air Curtains at all their Arrival Bus Gates to alleviate this problem. Apart from direct benefit of increased passenger comfort (due to cooler and more stable interior temperature), there were also other benefits such as less odour & dust and lower electricity usage as well.
