Introducing the UNIMAC ACM-250s Quiet Air series twin-cylinder Air Compressor! This is a trade quality 2-Cylinder unit ideal for anyone looking for the performance and reliability that only an oilless electric air compressor can provide. It is the ideal compressor for the home mechanic or DIYer!


The ACM-250s has a 1.1kW twin-cylinder motor. The 2850 RPM motor is more than twice as fast as our competitors. It has fan-forced cooling and aluminium heatsinks that keep this high-performance motor running cool.


This Unimac Quiet Air Series is engineered to be just that. Whisper Vortex cooling fans, Hush Baffle air intakes, and vulcanised rubber motor mounts and rubber tyres combine to give this an Lpa of only 61 dBa — that’s nearly library quiet!


This ACM-250s Oil-Free Air Compressor is powered by a twin-cylinder 1.1kw motor which is equivalent to a total output of 1.5 HP— up to 40% more than comparable models on the market!


With a 24L tank and 210 litres per minute air displacement the tank fills quickly.

It is capable of delivering a continuous 100-litre-per-minute air supply for a huge variety of applications.


Unlike petrol and other belt-driven models on the market, with this oil-free electric model you don’t have to worry about engine maintenance or replacing belts or pulleys.


The quick-connect Nitto outlet lets you use a wide array of tools including grinders, impact wrenches, welders, nail guns, grease guns, chisels and more. It also has automatic on-off pressure control.


The precise easy-to-read tank pressure and line pressure gauges take the guesswork out of filling and using your air compressor.


The UNIMAC has 2 large “easy-roll” wheels with rugged airless vulcanised tyres for shop use and its extended handle makes it a breeze to move. It also has a grab handle for ease of manoeuvring in tighter spaces.

It's safe to say, the UNIMAC ACM-250s silent air compressor blows the competition away!
