Borehole blowers

Borehole Blower for Rock

A borehole blower is a specialized tool used to remove dust, grit and debris from drilled holes in rock.
Cleaning the borehole is essential for a strong and secure anchorage, especially when installing chemical anchors or expansion anchors.

Key Features of a Borehole Blower

1 Air Blower Mechanism:

  • The blower uses compressed air or manual airflow to effectively remove fine dust and debris from the borehole.
  • This prevents dirt from weakening the bond of chemical anchors or the action of expansion anchors.

2​ Hose and Nozzle:

  • Flexible Hose: Reaches the full depth of the borehole, even on longer holes.
  • Directional Nozzle: Specially designed to direct air directly to the bottom of the hole for thorough cleaning.

3 Manual or Mechanical Operation:

  • Manual (Blower): Compact and portable, ideal for use in remote locations without power or compressed air.
  • Air tools: Connected to a compressor for more intensive and faster work.

4 Materials:

  • Hose: Durable and flexible material, often made of rubber or plastic.
  • Valve or pump: Resistant to high pressure and intensive use.

Function and benefits

  • Efficiency: Removes all loose materials from the hole, optimizing the adhesion of anchors.
  • Speed: Speeds up the process of hole cleaning compared to alternative methods such as brushing alone.
  • Clean working: Reduces the chance of dirt interfering with the placement of anchors or fixings.
  • Ease of use: Easy to use, even for inexperienced users.

Applications

  • Construction and civil engineering: For installing anchors in concrete and rock.
  • Climbing routes, canyoning and caving: When placing permanent anchors in natural rock.
  • Industrial installations: For precise and reliable fixings in hard substrates.

Tips for use

  • Cleaning sequence: First use a drill brush to remove loose dirt and then the drill hole blower for the fine dust.
  • Repeat as needed: Blow out the hole several times to ensure complete cleanliness.
  • Inspect the Hole: Visually check for dust and debris before placing the anchor.

A borehole blower ensures safe and durable anchors, a crucial step when working professionally in rock.
