Discover a new standard in performance and reliability with the Unimac ACM-1500s Quiet Air Series Quad Motor Air Compressor. This oil-free electric air compressor is ideal for various applications, from spray painting at smash repair shops to powering pneumatic tools on construction sites.

HALF THE NOISE
Experience ultra-quiet operation with noise levels up to 50% lower than comparable units. The Whisper Vortex cooling fans, Hush Baffle air intakes, and vulcanised rubber motor mounts and tyres ensure you can work without distractions, maintaining an operator level Lpa of only 59 dBa.

EXTRA MOTOR FOR LONGER LIFE
The unique quad motor design, featuring four twin-cylinder motors, allows the unit to run at lower RPMs. This reduces wear and extends the lifespan of your compressor. Independent Motor Start prevents power surges and accidental overloads, starting one motor at a time for optimal efficiency and safety.

TAILOR POWER TO YOUR NEEDS
With the ability to control each motor independently, you can tailor the power output to match your specific needs. Whether you require full power for demanding tasks or lower output for smaller jobs, the ACM-1500s provides flexibility and efficiency, ensuring you use only the necessary power.

CLASS-LEADING POWER
With four 0.85 kW twin-cylinder motors delivering a total output of 4.5 HP, the ACM-1500s provides up to 40% more power than other models. Use just the air you need with independent cylinder operation, reducing noise and extending compressor life.

MASSIVE 150L TANK
The 150L tank supplies up to 520 litres of air per minute, perfect for a wide range of tasks.

SERVICE-FREE DESIGN
Enjoy maintenance-free operation with this oil-free electric compressor—no engine maintenance, belt replacements, or pulley adjustments needed.

TWO NITTO OUTLETS
Use a variety of tools with two quick-connect outlets, including grinders, impact wrenches, welders, nail guns, grease guns, and chisels. Automatic on-off pressure control adds convenience.

EASY TO USE
Monitor and control your air supply with clear tank and line pressure gauges.

PORTABLE DESIGN
