Quiet oil-free compressor 50 L - 4 HP with induction motor
Quiet oil-free compressor, 50 litres, 4 HP
The top of the quiet range. Two pump heads, 420 L/min of flow and an induction motor, which is the real difference: an induction motor has no brushes to wear out, withstands long working days and does not lose performance with use.
With that flow you can now sand with pneumatic tools or paint continuously, which is where small compressors fall short. And it still runs at 72 dB and oil-free.
✅ Main advantages
420 L/min: almost double that of a 2 HP unit, for continuous-consumption tools.
Induction motor: brushless, designed for intensive use and a long life.
Two oil-free pump heads: they share the workload and run cooler.
72 dB despite the 4 HP: power without turning the workshop into a building site.
50 litres of reserve on wheels.
🏗️ What it is used for
Pneumatic sanders and continuous-consumption tools.
Spray painting in a booth or workshop.
Mechanical workshop with several air outlets.
Intensive daily use where a brushed-motor compressor cannot cope.
📋 Technical specifications
Power: 4 HP
Maximum pressure: 8 bar
Flow rate: 420 L/min
Speed: 2,850 r.p.m.
Air tank capacity: 50 litres
Noise level: 72 dB
Motor: induction
Lubrication: oil-free
💡 Professional tip: if you are going to use it every day, the induction motor pays for itself. A universal motor with brushes is cheaper to buy, but under intensive use it loses power and ends up needing a replacement part; the induction motor has no such wear component.
Frequently asked questions
What does it mean that it has an induction motor?
An induction motor has no brushes to wear out, so it is designed for intensive use and a long life. On this model it is combined with 4 HP and two oil-free pump heads.
Can I sand or paint continuously with it?
With 420 L/min at 8 bar it has the flow for continuous-consumption tools, such as pneumatic sanders, and for sustained spray painting, where small compressors fall short.
How much noise does it make with so much power?
Its noise level is 72 dB, a modest value for a 4 HP unit.
Does it need oil?
No, it is an oil-free compressor. It delivers air without lubricant and requires no crankcase maintenance.
What is the difference between its 50 litres and its 420 L/min?
The 50 litres are the air reserve and the 420 L/min is the flow the compressor produces. For continuous-consumption tools what matters is the flow rate, and this model offers almost double that of a 2 HP unit.
