UNIMAC 25L Oil-Free Electric Air Compressor 1.5HP

The UNIMAC ACM-250s is a trade-quality, oil-free electric air compressor designed for home mechanics and DIYers who need reliable performance without maintenance hassle.

Powered by a 1.1kW twin-cylinder motor (1.5 HP equivalent), this compressor delivers 100 litres per minute continuous air supply, with 210 litres per minute air displacement to fill the 24L tank quickly. The 2850 RPM motor is engineered for consistent, high-performance output suitable for grinders, impact wrenches, nail guns, grease guns and similar tools.

Quiet operation is built in. At 61 dBa—nearly library quiet—the compressor uses Whisper Vortex cooling fans, Hush Baffle air intakes, and vulcanised rubber motor mounts to minimise noise. Aluminium heatsinks and fan-forced cooling keep the motor running at optimal temperature during extended use.

The compact design includes two large easy-roll wheels with vulcanised tyres and an extended handle for effortless movement between jobs. A grab handle helps in tighter spaces. The Nitto quick-connect outlet accepts a wide range of pneumatic tools, with automatic on-off pressure control.

Easy-to-read tank pressure and line pressure gauges let you monitor performance at a glance. Unlike petrol or belt-driven models, this oil-free electric design requires no engine maintenance, belt changes, or regular servicing—just plug in and work.

Operating at 240V AC with a standard 10A Australian plug, the compressor includes two air filters, a handle, and wheels in the box. Minimal assembly is required before first use.

Check and adjust all valves and fittings before operation to prevent air leaks.
