Aiko Air Breaker A7 (20lbs) – Model AT-A7 Pneumatic Demolition Tool

Lightweight, High-Impact Pneumatic Power for Professional Demolition and Surface Preparation.

Demolition, surface preparation, and heavy masonry work require tools that can deliver relentless striking power without completely exhausting the operator. The Aiko Air Breaker A7 (Model: AT-A7) is a premium, highly maneuverable pneumatic demolition tool expertly designed to strike the perfect balance between high-impact breaking force and operator comfort. Whether your construction team is breaking through stubborn concrete slabs, chipping away old, hardened asphalt, or performing precise masonry alterations on a tight commercial renovation site, this 20-pound class air breaker delivers the reliable, heavy-duty performance you need to keep your project strictly on schedule. By harnessing the raw, consistent power of compressed air, the Aiko A7 ensures that contractors, municipal maintenance crews, and professional builders can rapidly complete demanding demolition tasks with significantly less physical effort.

At the core of this rugged pneumatic tool is a highly engineered internal striking mechanism designed for maximum kinetic energy transfer. Featuring a precision-machined 35mm piston diameter and a long 120mm piston stroke, the Aiko A7 consistently delivers an astonishing 1,250 blows per minute (b.p.m). This rapid, high-frequency striking action allows your chisels and points to effortlessly penetrate, fracture, and shatter dense, unyielding materials that would stall out lesser tools. To maintain this relentless, heavy-duty power, the breaker is equipped with a standard 3/4 PT air inlet and utilizes a robust 19mm hose size. This precise engineering guarantees a smooth, unrestricted, and highly efficient volume of continuous airflow from your industrial air compressor directly to the tool’s firing chamber, preventing pressure drops during sustained use.

While heavy-duty 60 to 90-pound pavement breakers are notorious for causing severe operator fatigue, intense vibration damage, and back strain, the Aiko Air Breaker A7 champions ergonomic usability. Weighing in at a highly manageable 7.2 kg (approximately 20 lbs) and measuring just 465mm in overall length, this compact breaker is exceptionally easy to handle, lift, and position. This lightweight profile makes it the absolute ideal choice for prolonged vertical downward demolition, awkward horizontal wall chipping, and working in highly confined trenches or restrictive spaces where larger, bulkier jackhammers simply cannot fit. Equipped to handle standard R26 x 80 shank sizes, the Aiko AT-A7 is a versatile, highly durable, and extremely efficient addition to any professional demolition toolkit.

Key Features & Benefits

• Optimized Piston Engineering: The 35mm diameter and 120mm stroke length maximize per-blow kinetic impact, ensuring deep material penetration with every strike.

🛡️ Compact & Anti-Fatigue Design

• Lightweight 20lb Class: Weighing just 7.2 kg, this tool significantly reduces operator arm and back fatigue, extending safe working hours and overall job site productivity.
• High Maneuverability: Its compact 465mm length makes it perfect for horizontal wall breaking, indoor renovations, and working in tight, restricted spaces.

⚙️ Reliable Pneumatic Efficiency

• Consistent Airflow: The 3/4 PT air inlet and 19mm hose compatibility ensure your tool receives the steady, high-volume compressed air required for uninterrupted performance.
• Standardized Shank: Utilizes a common R26 x 80 shank size, making it incredibly easy to source and swap out a wide variety of compatible chisels, points, and spades.

Technical Specifications

Usage Recommendations

• Air Supply: Always ensure your air compressor is properly rated to provide the necessary CFM (Cubic Feet per Minute) to maintain the breaker’s 1,250 b.p.m strike rate without losing line pressure.
• Tool Maintenance: Add a few drops of pneumatic tool oil directly into the air inlet before each shift to lubricate the internal piston and drastically extend the life of the tool.
