About Air Compressors for Mobile Mechanics
For van-mounted use, a 50L wheeled belt-drive at 8–10 CFM is the gold standard. It plugs into a 13A site supply or an inverter pack, and runs a ½″ impact long enough for full wheel changes.
For lighter mobile use (tyre top-ups, brake bleeding, blowing), a compact 24L portable at 5–6 CFM is plenty. For emergency roadside work, a heavy-duty 12V mobile compressor can run quick-release jobs without mains power.
