Silent oil-free compressor 100 L - 4 HP, 9 bar and 493 L/min
Quiet oil-free compressor, 100 litres, 4 HP
With 493 L/min at 9 bar this unit enters territory that small quiet compressors cannot reach: pneumatic sanders, light blasting and painting without pauses. These are tools that consume air non-stop and drain any 150 or 200 L/min compressor in under a minute.
And it does so with two oil-free twin-cylinder pump heads at 68 dB: belt-driven compressor power with a noise level you can live with in a closed workshop.
✅ Main advantages
493 L/min: flow for continuous-consumption tools.
9 bar maximum pressure: margin for long hoses and several outlets.
Two oil-free pump heads: clean air without coalescing filters.
100 litres of reserve to absorb peaks in demand.
68 dB: genuinely quiet for its 4 HP.
🏗️ What it is used for
Pneumatic sanders and tools with sustained consumption.
Paint booths and bodywork.
Workshops with two or three operators using air at the same time.
Fixed pneumatic installations in a small industrial unit.

💡 Professional tip: before deciding between the 3 HP model and this one, add up the consumption of the tools you will use at the same time and add 30%. The flow a compressor quotes is air drawn in, not air delivered under pressure: if your total comes close to the unit's limit, the motor will never stop and its service life will be gone within a year.
Frequently asked questions
Can I use pneumatic sanders or light blasting?
Yes, with 493 L/min at 9 bar this unit is designed for pneumatic sanders, light blasting and painting without pauses, tools that consume air continuously.
How much noise does it make?
It runs at 68 dB with two twin-cylinder pump heads and 4 HP.
Does it need oil?
No, it is an oil-free compressor and delivers air without lubricant, with no need for additional coalescing filters.
How much flow do I really need?
Add up the consumption of the tools you will use at the same time and add 30%. If the total comes close to the 493 L/min limit, the motor will never stop and will wear out sooner.
What is the difference between the 100 litres and the 493 L/min?
The 100 litres are the reserve that absorbs peaks in demand and the 493 L/min is the air produced every minute. The flow rate decides which tools you can run and the tank decides how often the motor starts.
