MZB Belt-Driven Compressor 300 l, 1153 l/min, 12.5 bar, 7.5 kW / 380 V (MZB4V105125)

300 litres, 1153 l/min, 12.5 bar. This is no longer “a compressor for the workshop” — it is the compressed-air installation for the whole shop.

When mechanics on forums warn each other off the “cheap three-hundred” and write that a workshop needs at least 270–300 litres, at least 500 l/min and 4–5.5 kW on three phases, they are describing exactly this class. This model has 7.5 kW and 1153 l/min — reserve beyond those requirements — and two-stage compression giving 12.5 bar.

How much air your tool needs

Makers quote intake. Below is the recommended intake with margin:

At 1153 l/min this is the only model in our range that runs a sandblaster — and blasting is exactly where an undersized compressor usually gives itself away.

Frequently asked questions

Isn't this too much for one workshop?
If you have one bay and a 1/2″ wrench — yes, take a smaller model. This one makes sense with several bays, with sandblasting, or when you plan to grow and do not want to replace the compressor in two years.

Why 12.5 bar?
Truck tyres are inflated to 9–10 bar, and a long installation loses pressure on the way. With an 8-bar compressor there is sometimes too little left at the end of the line.

Invoice?
Yes, VAT. Companies with a valid EU VAT number buy at the net price.
