Bangkok Aviation Fuel Services Public Company Limited or BAFS is sole aircraft fuelling company at Bangkok International Airport, Thailand. Main product serviced is JET A-1 .

JET A-1 is transported to BAFS' depot via dedicated and integrated pipelines that are connected through the Fuel Pipline Transportation Limited (FPT) and the Thai Petroleum Pipeline Company Limited (THAPPLINE). Only certified JET A-1 is received. Before being stored in storage tanks JET A-1 is passed through pre filters and filter water separators to remove particulate matter and separate water. Then, JET A-1 is allowed to settle in storage tanks for at least 24 hours before being released for delivery.

JET A-1 is pumped through filter water separators by hydrant pumps into underground hydrant fuelling system installed under the aircraft parking area. Where the hydrant fuelling system is available dispensers are used to deliver JET A-1 into aircraft fuel tanks. Where the hydrant fuelling system is not available refuellers are used instead.

Besides, all dispensers and refuellers are installed with the On-Track Computer System in order to standardize the service with a focus on high technology, accuracy, speed and safety
