Continuous-duty compressor 4 HP - 590 L/min at 10 bar and 20 L
Professional continuous-duty compressor, 590 L/min
The top of the single-phase continuous-duty range. 590 L/min at 10 bar sustained for 2 hours at a stretch: that is more sustained flow than many three-phase belt-driven compressors deliver, and it runs on 230 V.
The 20-litre air tank and the 1,420 r.p.m. motor define what it is made for: not for storing air, but for producing it without stopping. It is the unit for large spraying machines, blasting and any job where air consumption is constant and high.
✅ Main advantages
590 L/min sustained: industrial-grade continuous flow on single-phase.
Continuous duty for up to 2 hours with no rest cycles.
10 bar of pressure for demanding tools and spraying.
Tubular frame with pneumatic wheels: it moves over rough site ground.
Motor at 1,420 r.p.m.: low speed and a long life.
🏗️ What it is used for
Large-scale spraying of mortars, textured wall finishes (stipple) and coatings.
Light blasting and surface cleaning.
Several pneumatic tools working at the same time on site.
Equipment hire and intensive professional use.

💡 Professional tip: 4 HP single-phase on a building site calls for a serious power supply. Check the fuse board before buying it: with a small generator or a line of just 16 A, the starting surge will trip the protection again and again. Allow for at least 20-25 A and a generously sized cable if you are going to use an extension lead.
Frequently asked questions
How long can it work at a stretch?
Up to 2 hours in continuous duty, maintaining 590 L/min at 10 bar, with no rest cycles.
What electrical installation does it need?
It is a 4 HP unit at 230 V and its start-up demands a serious power supply. With a line of just 16 A or a small generator the protection will trip; allow for at least 20-25 A and a generously sized cable if you use an extension lead.
Can I use several tools at the same time?
Yes. With 590 L/min it is suitable for several pneumatic tools working at the same time on site, provided the combined consumption does not exceed that flow rate.
Is it suitable for large-scale spraying or blasting?
Yes, it is designed for large-scale spraying of mortars, textured wall finishes (stipple) and coatings, and for light blasting and surface cleaning.
How does it differ from the 3 HP continuous-duty model?
It steps up to 4 HP and 590 L/min compared with 330 L/min, and the air tank goes from 3 to 20 litres. Both deliver 10 bar in continuous duty.
