Belt compressor 25 L - 3 HP and 365 L/min at 10 bar
25-litre belt-driven compressor
A belt-driven compressor in a compact format, which is an unusual combination. The interesting part is the speed: it runs at 1,375 r.p.m., less than half that of an equivalent direct-drive compressor, and yet it delivers 365 L/min at 10 bar.
That is the whole advantage of the belt: the motor drives the head through a pulley, so the head can turn slowly and be large instead of fast and small. The practical consequence: it runs much cooler, makes less noise and withstands full working days where a direct-drive compressor would have to stop to rest.
✅ Main advantages
Belt transmission: ready to work many hours a day.
10 bar of pressure: headroom for demanding tools and long hoses.
365 L/min while turning at only 1,375 r.p.m.
Lubricated cast-iron head: dissipates heat and can be repaired.
Only 25 litres: a professional compressor that still fits in a van.
🏗️ What it is for
Workshops with daily, prolonged use of compressed air.
Pneumatic impact tools and spray painting.
Building sites and jobs that demand a true 10 bar.
Equipment hire and professional use.

💡 Professional tip: a belt-driven compressor does contain oil and it needs to be checked. Check the level at the sight glass with the unit cold and level, and change it after the first 100 hours and then every 500. It is the maintenance that separates a head that lasts fifteen years from one that seizes in two.
Frequently asked questions
How often does the oil need changing?
According to the specification sheet, check the level at the sight glass with the unit cold and level, and change it after the first 100 hours and then every 500 hours.
Isn't 25 litres too little?
It is a compact air tank, designed to be moved easily. It compensates with 365 L/min at 10 bar, but with little reserve the motor will start more often than on a model with more litres.
What advantage does the belt have over a direct-drive compressor?
The head turns at only 1,375 r.p.m., so it runs cooler, makes less noise and withstands longer working days. That is why it is used in workshops.
Does it need a three-phase supply?
No, it is single-phase at 230 V. With 3 HP, ask your electrician to confirm that the line is suitable for its consumption.
What tools can I use?
With 365 L/min and 10 bar it runs impact wrenches, blow guns and spray guns. For pneumatic sanders in continuous use, check the flow each one requires.
