Side inlet Air swivels are primarily used in reverse circulation drilling. An Air swivel Also known as a flushing head is a Drilling tool attached to the top of the drill pipe, RC pipe or tubing to form a connection with the compressor or pump to allow circulation of the drilling mud, air or water.
In Reverse circulation applications, an air swivel it allows the cuttings to be flushed upward into the pipe and gives a port for the cuttings to be returned. A flushing head works by allowing the drill pipe to rotate while the side hose remains stationary. Compressed air is blown into the stationary side inlet of the flushing Head and cuttings are returned through the drill pipe.
