UNIMAC 40L Oil-Free Electric Air Compressor 2.0HP

The UNIMAC ACM-400s is a trade-quality, twin-cylinder oil-free electric air compressor designed for reliability and quiet operation. It delivers 125 litres per minute of continuous air supply from a 40L tank, making it suitable for grinders, impact wrenches, nail guns, grease guns and a wide range of pneumatic tools.

Twin-Cylinder Performance
The 1.5kW twin-cylinder motor runs at 2850 RPM and produces 2.0HP equivalent output—up to 40% more power than comparable models. Fan-forced cooling and aluminium heatsinks keep the motor running cool during extended use.

Ultra-Quiet Operation
Engineered for low noise, the ACM-400s features Whisper Vortex cooling fans, Hush Baffle air intakes, and vulcanised rubber motor mounts. Operating at just 62 dBa, it’s quiet enough for workshop environments without disturbing others.

Two Nitto Outlets
Quick-connect Nitto outlets let you connect multiple tools simultaneously. Automatic on-off pressure control manages tank pressure between 86PSI restart and 116PSI working pressure.

Service-Free Design
Being oil-free and electric, this compressor requires no engine maintenance, belt replacements or oil changes—unlike petrol-driven alternatives. Easy-to-read tank and line pressure gauges show you exactly what you’re working with.

Portable and Practical
Weighing 29kg, the compressor sits on two large easy-roll wheels with airless vulcanised tyres. An extended handle and grab points make moving and manoeuvring straightforward, even in tighter spaces.

Runs on standard 240V AC power with a 10A Australian plug. Minimal assembly required. Check the user manual online for setup and operating instructions.
