Unimac 18HP Industrial Petrol Air Compressor 150L

The Unimac UMC-15P is an industrial petrol air compressor with an 18HP OHV engine and 150-litre receiver tank. It delivers 1180L/min free air delivery at 115PSI, making it suitable for sustained high-demand workshop and construction applications.

Powered by a robust 18HP petrol engine with electric key start (battery included) and recoil backup, this compressor maintains consistent 115PSI pressure under heavy loads. The large 6.5-litre fuel tank ensures extended runtime between refills.

The Tri-V piston configuration features three 90mm coated sleeves operating at lower speeds than conventional designs. Lower rotational speeds mean reduced operating temperatures, which decreases moisture in the compressed air. This keeps your tools drier and extends equipment life—particularly important for spray painting, where moisture affects finish quality.

Specifications include working pressure of 115PSI, restart pressure of 85PSI, and pop-off at 160PSI. The compressor runs at 85dB and weighs 160kg. Engine oil (10W-30 to 15W-40 non-synthetic) and regular unleaded 95+ RON fuel are required; the tank must be drained after each use to maintain starting reliability.

Includes battery and online manual access. Dimensions: 49 × 126 × 98cm.

Check the user manual online before commissioning, and ensure all valve and fittings are sealed to prevent air leaks.
