If you're looking for a compressor suitable for professional use, the Airpress HK 425-100 400V is a good choice. It has a stable net air output of 255 liters per minute and a total power output of 2,200 watts. With specifications like that, you can be sure that you can attach any type of pneumatic tool to the compressor and get the results you're looking for. Thanks to the 100-liter tank capacity, you'll hardly ever have to take a break from your work. The maximum air pressure is 10 bar, but you can use the pressure switch to set it manually. The manometer makes it easy to check the pressure. Despite its higher power output, the HK 425-100 400V is less noisy than you might expect, because it's oil lubricated.
