Who uses the AC35/270/600/D and for what
The Bernardo AC35/270/600/D is a two-stage stationary compressor with a 270-liter tank and an effective flow rate of 480 l/min at 10 bar: sized for continuous professional use in mechanical workshops, body shops, paint shops, woodworking workshops, and production centers that require a constant supply of compressed air for multiple tools simultaneously. The low speed (1450 rpm) ensures long life and a low sound level (78 dB(A)) compared to high-speed compressors. The double compression stage produces cooler and drier air than a single-stage, reducing condensation in the circuit. In Krollit's customer workshops, it is used as a central pneumatic system.
Who is the Bernardo AC35/270/600/D for?
| Profile |
Compatibility |
Reason |
| Hobbyist |
Not suitable |
Requires three-phase 400V and has industrial workshop dimensions. For hobby use, consider the oil-free compressor AC/PRO/250/24/F/W in single-phase. |
| Professional workshop / body shop |
Ideal |
480 l/min at 10 bar: sufficient to continuously power 2 standard pneumatic tools simultaneously. |
| Industrial production |
Ideal |
270 L tank and low speed (1450 rpm) for continuous cycles without overheating. |
Not suitable for: domestic or hobby use; installations without three-phase 400V; pressures above 10 bar.

Frequently Asked Questions
What is the difference between a single-stage and a two-stage compressor?
In a single-stage compressor, the piston compresses air in a single stroke to the final pressure. In a two-stage compressor (AC35/270/600/D), the first stage compresses to an intermediate pressure, the air cools in an intercooler, then the second stage brings it to the final pressure. Result: cooler air (less condensation), more stable final pressure, reduced wear, longer lifespan. For continuous professional use, a two-stage compressor is always preferable.
How many pneumatic tools can it power simultaneously?
With an effective flow rate of 480 l/min at 7 bar, the compressor continuously powers tools with a total consumption of up to approximately 408 l/min. For reference: pneumatic angle grinder 180–250 l/min, HVLP spray gun 100–150 l/min, pneumatic wrench 120–180 l/min.
Does it require periodic maintenance?
Yes: oil change every 250–500 hours (according to manual), drain condensation from the tank (with each use), clean air filter (monthly), check drive belt (biannually). Original Bernardo oil, filters, and maintenance kits available with 3–5 business day shipping.
Does it require fixed installation or can it be on wheels?
The AC35/270/600/D is designed for stationary installation. The horizontal structure is stable on the floor. Contact Krollit for installation requirements and optional accessories.
What is the difference between AC35, AC38, and AC50?
AC35/270/600/D: 4.0 kW, 480 l/min flow rate, 119 kg weight — the lightest. AC38/VER/270/850/D: 5.5 kW, 700 l/min flow rate, vertical, 151 kg — the most vertically compact. AC50/VER/270/1200/SD: 7.5 kW, 840 l/min flow rate, vertical, 225 kg — the most powerful. The choice depends on the required flow rate and available space.
