Structure & Configuration

Functioning as a mine rock drill air compressor, the W3.5‑5 air compressor adopts an enhanced integrated mobile base frame fitted with reinforced travelling wheels and towing assemblies for easy relocation across construction zones, mining areas and uneven mountain terrain. The thickened frame resists impact and bumping and supports prolonged continuous operation in dusty, muddy open‑air surroundings.

Fitted with an industrial diesel power unit, the compressor operates independent of mains electricity. The compression host and power assembly are fine‑tuned together to maintain stable air output and support parallel operation of several rock drills and jackhammers. As a reliable jackhammer supporting air compressor, it holds sufficient air reserve to meet high‑consumption demands from multiple‑tool joint work.

The control panel is simplified, integrating start‑stop control, pressure readout and multi‑level safety protection modules for straightforward onsite operation. Built‑in dust‑proof, water‑proof, overload and over‑heat protection structures reduce failure risks under harsh site conditions, making it a practical rock drill dedicated air compressor.
