Who uses the AC/PRO/250/24/F/W and for what
The Bernardo AC/PRO/250/24/F/W is a professional 24-liter oil-free compressor for use in workshops, carpentry labs, and body shops: without oil in the circuit, the produced air is free of oil contaminants — essential for spray guns, painting, tires, and pneumatic tools where oil would compromise work quality. At 75 dB(A), it is among the quietest in its 24-liter professional category. The effective flow rate VDMA 4362 of 130 l/min is the real continuous use value — the 230 l/min value is the no-load suction capacity. Being single-phase 230V, it can be used with any standard outlet without a three-phase system.

Frequently Asked Questions
What does "oil-free" mean and why is it important?
An oil-free compressor does not use oil to lubricate the pistons — it uses self-lubricating materials (PTFE or graphite). The air produced is therefore completely free of oil mist. For spray guns and painting, this is crucial: even minimal oil contamination in the air causes defects in the paint film (craters, bubbles, poor adhesion). For tire inflation and light pneumatic tools, the benefit is smaller, but the advantage is the lack of maintenance (no oil changes).
What is the difference between 230 l/min suction and 130 l/min effective flow rate?
Suction capacity (230 l/min) measures how much the compressor aspirates under no-load — a theoretical value. The effective flow rate VDMA 4362 (130 l/min) measures how much compressed air at 7 bar the compressor produces continuously in the real world. To choose the right compressor, always use the effective flow rate: a tool with 80 l/min consumption will have sufficient margin with 130 l/min VDMA.
Is 75 dB(A) quiet for a professional compressor?
Yes. Traditional piston compressors produce 85–95 dB(A). The 75 dB(A) of this model is the result of low-speed oil-free technology (1,450 rpm vs 2,800–3,000 rpm for standard models) and acoustic insulation. For comparison, normal conversation is at 60 dB(A) and a household vacuum cleaner at 75–80 dB(A).
Does it require periodic maintenance?
Reduced maintenance compared to oil compressors: no oil changes. Periodic operations: drain condensation from the tank (daily or weekly), check air filter (monthly), check safety valve (annually). Original Bernardo spare parts available with 3–5 working days shipping.
How many spray guns can it power simultaneously?
With an effective flow rate of 130 l/min at 7 bar, the compressor powers a standard HVLP spray gun (consumption 100–150 l/min) continuously with small tank recharge breaks from the 24-liter tank. For two simultaneous guns, the flow rate is not sufficient — a compressor with a higher effective flow rate is needed.
