Unimac 150L 4.5HP Oil-Free Quiet Air Compressor with Quad Motors

The Unimac ACM-1500s is an oil-free electric air compressor designed for spray painting, pneumatic tools, and heavy-duty workshop applications. Its quad motor design and noise-reducing engineering deliver reliable performance with minimal disruption.

QUIET OPERATION
Noise levels reach just 59 dBa—up to 50% lower than comparable units. Whisper Vortex cooling fans, Hush Baffle air intakes, and vulcanised rubber motor mounts and tyres minimise vibration and sound.

QUAD MOTOR DESIGN FOR LONGEVITY
Four twin-cylinder motors run at lower RPMs, reducing mechanical wear and extending compressor lifespan. Independent Motor Start prevents power surges by engaging motors one at a time. You can control each motor independently to match power output to your specific task—full capacity for demanding work or reduced output for lighter jobs.

SUBSTANTIAL TANK AND AIRFLOW
The 150L receiver tank supplies 280 litres of air per minute at 7 bar, providing sustained performance for a range of tools including grinders, impact wrenches, welders, nail guns, and chisels. Working pressure reaches 116 PSI with automatic on-off pressure control.

OIL-FREE AND SERVICE-FREE
No oil changes, belt replacements, or pulley adjustments required. Dual pressure gauges let you monitor both tank and line pressure. Two quick-connect Nitto outlets support simultaneous tool use.

PORTABLE AND BUILT FOR MOVEMENT
Four large wheels with rugged airless tyres and an extended handle allow easy repositioning. Two grab handles aid manoeuvrability in confined spaces.

Designed for professional workshops and construction sites, this compressor combines durability with operator comfort. Check and adjust all valves and fittings before first use to prevent air leaks.
