BLASTBAGS™

BLASTBAG™ ACE II

The non-metallic, non-dangerous goods BLASTBAG™ with push-latch inflation.
· SKU 21-251

BLASTBAG ™ ACE is the safest and most user-friendly inflation solution on the market. It is a chemical-inflation gasbag designed to create a stable air deck in a wide range of blasting conditions. Its simple setup and consistent inflation make it a practical option for underground headings, open pit benches, and areas where ground conditions may vary. The BLASTBAG™ ACE inflates through a controlled chemical reaction, removing the need for pumps or external equipment and helping crews work more efficiently.

Each BLASTBAG™ ACE is made from non-metallic, non-sparking materials and contains no hazardous, toxic, or flammable components. This makes it suitable for sites with strict safety requirements and helps reduce the chance of false trips or unintended tool interactions.

Once placed, the BLASTBAG™ ACE II forms a stable barrier inside the hole, improving energy distribution and supporting better blast quality. It is lightweight, easy to position, and requires minimal training, which helps reduce preparation time and supports repeatable, consistent use across different teams.

Key qualities include:

  • Chemical-reaction gas inflation for predictable expansion

  • Non-metallic construction suitable for sensitive environments

  • User-friendly setup with no external equipment needed

  • Stable air decking to manage energy and reduce common blast issues

  • Reliable performance in both underground and surface conditions

The result is a straightforward, dependable air decking solution that fits naturally into daily blasting workflows.

Why this product

Why BLASTBAG™ ACE II

Chemical reaction gas

Second-generation chemical gas system inflates faster and more consistently than the original ACE.

Why it matters: Quicker deployment, more predictable air decks. An upgrade you'll notice on the first round.

Non-metallic material

Fully non-metallic body. No interference with electronic detonators or RF-sensitive initiation.

Why it matters: Use with any initiation system without safety concerns. Universal compatibility.

False trip reduction

Improved activation mechanism reduces premature inflation during handling and insertion.

Why it matters: More bags reach target depth intact. Less waste, fewer re-loads.

User-friendly design

Pull-tab activation and simple deployment. No hoses, no connections, no moving parts.

Why it matters: Minimal training for new crew members. Consistent deployment across the team.

Reliable inflation

Upgraded chemical charge delivers consistent fill pressure in temperatures from -20°C to 50°C.

Why it matters: Works in every climate condition your operation faces. No seasonal performance drop-off.

Underground suitable

Self-contained with no external air supply. Compact form factor for tight headings.

Why it matters: No hose runs to the face. Deploy air decks in confined spaces with zero infrastructure.

Benefits

Built for the bench.

Protected cartridge

The aerosol cartridge sits inside a rigid housing — survives the abuse of a normal bench day.

User-friendly inflation

Designed to be the safest, most forgiving inflation in the BLASTBAG family. New operators can pick it up quickly.

Field-proven design

Second generation of the ACE platform — refinements based on years of bench feedback.

Built for every condition

Built for every condition.

Crews new to gas bags

If you're training operators on air decking for the first time, the ACE II is the most forgiving way in.

Production benches

Fast cycle, simple workflow. Drop, fire, move.

Mixed UG/OP fleets

Rated UG/OP. Works wherever a SOLO or EVO would.

When to pick each
BLASTBAG™ SOLO

Pick BLASTBAG™ SOLO when you're running surface benches and want the most-used aerosol gas bag on the market. Self-contained, single-operator deploy, no extra gear — ~30 seconds per hole. Two-speed actuator lets you inflate slow or fast depending on the situation. Sizes from 4.5" to 12.25" (114 – 311 mm) cover every standard production hole. Class 9 DG — stores and ships under aerosol rules.

BLASTBAG™ EVO

Pick BLASTBAG™ EVO when you want aerosol convenience without the SKU sprawl. Two sizes — Hawk (4" – 6") and Eagle (6" – 9⅞") — cover most surface holes, so you stock less and make one decision on the bench instead of four. Single bladder seals against the hole wall; pressure sleeve controls inflation speed. Class 9 DG.

BLASTBAG™ ACE II

Pick BLASTBAG™ ACE II when storage or transport rules make aerosol products a hassle, or when you're running metal-detector conveyors that throw false trips. Chemical reaction inflation — no aerosol, no metal components, non-DG. Same air-deck performance as SOLO and EVO, just delivered through a controlled chemical reaction instead of pressurized gas. Sizes 3" through 10⅝" (76 – 270 mm).

BLASTBAG™ AERO

Pick BLASTBAG™ AERO when you're underground with service air lines available. Compressed-air operated, dual-bladder construction, snap-on coupling for fast connect/disconnect. Works in any direction — up holes, down holes, even underwater. Sizes 2.5" through 12.25" (64 – 311 mm). Best-seller in underground and the cleanest install when air is already on site. Non-DG.

BLASTBALL™

Pick BLASTBALL™ when the hole is wet or you've got breakthroughs and cracks to seal. The only inflatable in this collection rated for wet-hole deployment — lower it through water on a drop line, then inflate with compressed air. Reinforced rubber bladder with nylon webbing handles -58°F to 185°F (-50°C to 85°C). Sizes 2.5" to 8" (64 – 203 mm). Underground development specialist.

MITIPLUG

Pick MITIPLUG™ when you're loading emulsion or ANFO into underground upholes and need a mechanical plug that creates an air deck AND retains the column. Flexible pilgrim-hat fins fold back on insertion, then lock in place — and the fins let gas through. Revised design includes downline protection. Fits 2.5" to 4" (64 – 102 mm). The most popular plug for underground emulsion upholes.

ROCKRIVETS

Pick ROCKRIVET™ when you need to create a controlled air deck on a trim or pre-split row, or hold the charge column with maximum retention and downline pass-through. Collet-style fins bite the hole wall and don't walk, twist, or shift. Iron ore case study: 38% smaller P80 fragment size with ROCKRIVETS installed. Sizes 3" to 9" (76 – 230 mm), rigid for heavier loads, semi-rigid for tighter holes.

SLUMPSTOPPA™

Pick SLUMPSTOPPA™ when you're loading emulsion in underground upholes and need a gas-permeable retention device to hold the column without compromising the gassing reaction. Polymer bristles with a stainless steel spine hold the column while letting emulsion gas through. Fits 2.5" to 4.5" (64 – 115 mm). The dedicated emulsion-slump solution for underground upholes.
