Blow tube for Rock

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

Key Features of a Blowetube

1 Air Blower Mechanism:

• The blower uses compressed air or manual airflow to effectively remove fine dust and debris from the drillhole.
• 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 blowtube ensures safe and durable anchors, a crucial step when working professionally in rock.
