Mixing Nozzle & Air Pump
The consumables for chemical anchoring: static mixing nozzles that blend the resin as it is dispensed, and an air pump that clears dust from the drilled hole.
What are the mixing nozzle and air pump?
These are the consumables that go with a chemical anchor. The static mixing nozzle blends the resin and hardener together as they are dispensed, so the adhesive cures correctly — fit a fresh nozzle for each cartridge or after a break in work. The air pump (blow-out pump) clears drilling dust from the hole before injection.
A clean hole is essential for full bond strength: loose dust at the bottom of the hole is the most common cause of a weak chemical fixing.
Where it is used
- With any injectable chemical anchor cartridge
- Mixing nozzle: dispensing and blending resin into the hole
- Air pump: blowing dust out of the drilled hole before injecting
Main advantages
- Static nozzle mixes resin and hardener automatically as dispensed
- Correct mix means correct curing and full bond strength
- Air pump removes the dust that most often weakens a chemical fixing
- Fit a fresh nozzle per cartridge or after a pause

Frequently asked questions
How often should the nozzle be changed?
Fit a fresh mixing nozzle for each new cartridge, or after a break in work, so the resin does not cure inside the old nozzle.
Why clean the hole with the air pump?
Loose dust prevents the adhesive from bonding to solid concrete and is the most common cause of a weak chemical fixing. A clean hole is essential for full bond strength.
