AIRBOLT Inflation Device: Precision and Efficiency in Bolt Expansion
At FORMIN, we develop cutting-edge solutions for the installation of anchor bolts in mining and construction. Our FORMIN Inflation Device is a key accessory in the bolt expansion process, ensuring a secure and efficient fixation in the rock mass.
What is the FORMIN Inflation Device?
The FORMIN R32 Inflation Device is an essential component of the inflation unit for our anchor bolts. Its main function is to inject air and water at pressures up to 300 bar, allowing the hydro-pneumatic expansion of the bolt until it reaches its required external diameter.
Benefits of the FORMIN Inflation Device

Uniform and controlled expansion
Ensures a precise fit of the bolt in the rock mass.
High performance
It operates at 300 bar pressure, maximizing anchorage efficiency.
Easy installation
It connects to the bolting machine via an R32 shank, with possible adaptations according to requirements.
Strength and durability
Manufactured with high-quality materials to withstand extreme conditions.
- Installation of anchor bolts in underground mining
- Anchoring in tunneling projects and civil excavations
