A Super Silent Air Track is 100% flat and 100% airtight because the tracks are completely glued.
A fan in the flight case inflates the track to the right pressure. The track can also be inflated with a mini blower. This blower needs to be disconnected when the track has the right pressure.
We offer Air Tracks in 6 different dimensions and in 2 different heights. On request, we can also produce custom dimensions.
