Belt compressor 50 L - 3 HP and 320 L/min at 10 bar
The logical entry point into belt-driven compressors: 50 litres, 3 HP and 10 bar, in a size that can still be moved around the workshop without difficulty.
Compared with a direct-drive compressor at roughly the same price, you are not buying more air delivery here: you are buying hours of service life. The belt allows the pump head to turn at half the revs, and a lubricated cast-iron pump head turning slowly can withstand daily use that would burn out a direct-drive compressor in a couple of seasons.
✅ Key benefits
Belt drive: designed to work every day, for many hours.
10 bar maximum pressure compared with the usual 8 bar.
320 L/min of sustained air delivery.
Lubricated cast-iron pump head: dissipates heat and can be repaired.
50 litres with wheels: professional yet manageable.
🏗️ What it is for
Mechanical and bodywork workshops with daily use.
Impact tools, ratchets and light pneumatic sanding.
Spray painting and finishing.
Professional carpentry and assembly.

💡 Pro tip: the most expensive mistake when using a new belt-driven compressor for the first time is starting it without removing the crankcase transport plug or without checking the oil level. Many are supplied without oil from the factory to avoid spills during shipping. Check the sight glass before the first start: thirty seconds running dry is enough to seize the pump head, and that is not covered by the warranty.
Frequently asked questions
What is the difference between this belt-driven compressor and a direct-drive one?
Here the motor drives the pump head via a belt and pulley, so it turns at 1,420 rpm and copes better with daily use. It delivers 320 L/min at 10 bar with 3 HP.
Do I need three-phase power?
No. It is a 230 V single-phase unit and works from a 230 V socket. Given its 3 HP rating, ask your electrician to confirm that the circuit and its protective devices are suitable.
What should I do before the first start?
Check the oil level in the sight glass and remove the crankcase transport plug. According to the data sheet, many units arrive without oil from the factory and starting them dry can seize the pump head.
Which tools can it drive?
With 320 L/min and up to 10 bar it is suitable for impact wrenches, ratchets, blow guns and spray painting. A pneumatic sander in continuous use may need more air delivery; always compare with the consumption stated by the tool manufacturer.
What is the 10 bar maximum pressure for?
It gives you headroom compared with the usual 8 bar: it makes up for the pressure drop in hoses and filters. At the nozzle you will work at a lower pressure, which you set with the filter regulator.
