Tuned for pneumatic tool requirements, this air compressor for rock drill and jackhammer outputs free air delivery of 2.85m³/min at rated working pressure 5bar. This 5 bar construction air compressor features fast start‑up response and steady air output. No obvious pressure drop occurs during long‑time full‑load running. The unit works for high‑frequency rock drilling and breaking tasks at sites without mains power supply, acting as reliable off‑grid air compressor for remote job‑sites.

Structure & Configuration

This air compressor for rock drill and jackhammer, also known as mine rock drill air compressor, adopts integrated mobile chassis fitted with heavy‑duty wheels and towing structure for relocation on construction yards, mine zones and mountain terrains. Reinforced frame absorbs bump and impact against dusty and wet field surroundings for long‑term outdoor operation.
Equipped with industrial diesel engine, the W2.85‑5 air compressor runs without grid power. Matched between compressor host and power assembly, it keeps responsive and stable air flow to sustain continuous running of rock drill and jackhammer. This jackhammer supporting air compressor is well‑calibrated for heavy‑duty pneumatic equipment.
Simplified control panel covers start‑stop, pressure reading and safety protection. Operators can finish onsite operation with simple steps. Built‑in dust‑proof, water‑proof, overload and overheat protection lowers failure risks caused by rough working conditions for this rock drill dedicated air compressor.
