Reverse Circulation Air Swivel
Hole Products offers a variety of air swivels for use on reverse circulation drilling operations. Reverse Circulation air swivels can be customized to connect any pin or box connection, and designed for use on any rig. Air swivels attach to the top of the Reverse Circulation drill rods or tubing to form a connection with the compressor or pump to allow circulation of the drilling mud, air, or water. The swivel feeds air or fluids into the outer drill rod, while maintaining a sealed inner tube to allow the cuttings to flow to the surface. Reverse Circulation swivels allow the drill pipe to rotate, while the side port for the cuttings to be returned remains stationary. Please contact your Hole Products representative for additional details and product availability.
