You don’t build a great RC drill rig hydraulic blow down valve overnight. Harlsan’s Hydraulic Blow Down represents years of development and is reflected in its reputation within the RC drilling industry today.
While manual RC Drilling Blow Down operations are time-consuming and involve safety issues, the Harlsan Hydraulic Blow Down can clear RC drill string blockages, back flush holes, improve sample purity and clear bit face blockages at the flick of a switch. The Blow Down is available in single port design for blow down function only or double port for blow up and blow down operation.
“The durability, availability of parts & ease of service keeps downtime to a minimum. We simply drill more meters with Harlsan Blow Downs on our rigs.”
Jason Howie, Operations Manager – Ranger Drilling
