UNIMAC ACM-500s 50L Oil-Free Air Compressor 3.0HP

The UNIMAC ACM-500s is a trade-quality oil-free electric air compressor built for sustained performance and low noise operation. Powered by dual 1.1kW motors (3.0HP combined), it delivers 200 litres per minute from a 50L tank, making it suitable for grinders, impact wrenches, welders, nail guns, and other pneumatic tools.

This compressor operates at just 64 dBa—library quiet—thanks to Whisper Vortex cooling fans, Hush Baffle air intakes, and rubber motor mounts. The Electronic APC system equalises output between the two motors, ensuring maximum efficiency and fast tank filling.

With two quick-connect Nitto outlets, you can run multiple tools simultaneously. The 50L receiver tank maintains steady air supply, while precise tank and line pressure gauges let you monitor performance at a glance. Automatic on-off pressure control means the unit switches as needed, reducing energy use.

Unlike petrol and belt-driven models, there is no engine maintenance, belt replacement, or oil changes required. The portable design includes two large easy-roll wheels with airless tyres, rubber anti-skid feet, an extended handle, and a grab handle for tight spaces.

Runs on standard 240V AC power (10A plug). Minimal assembly required; check and adjust valves/fittings before first use to prevent air leaks.
