Purge Air

Purge Air

The is an intrinsically safe fuel tank entry system which allows safe entry into the hazardous environment of an aircraft’s fuel tank. As aircraft fuel tanks also contain vital ancillery equipment, access is often required in order to carry out inspection and maintenance programmes

The PurgeAir is proven to gain entry to an aircraft fuel tank within 1 hour.

When positioned alongside the aircraft the container forms the control centre for the operation.When entering and performing maintenance on an integral fuel tank, all fuel must be emptied from the tank and strict safety procedures must be followed. Fuel vapours must be purged from the tank and respiratory equipment must be used by the technician.
