Frequently Asked Questions
For what professional uses is the Bernardo Portable Compressor dimensioned?
With a 100-liter tank and a maximum pressure of 10 bar, the Bernardo Portable Compressor is dimensioned for: spray guns for painting (requiring 6–8 bar, 150–300 l/min), pneumatic screwdrivers (6 bar, 100–150 l/min), compressed air tools in mechanical workshops, light sandblasting. The 100-liter tank ensures sufficient autonomy for continuous work without frequent stops for refilling.
400 V three-phase — does it require a special electrical system?
Requires a 400V three-phase system — not available in standard private homes. Before purchasing, verify the presence of three-phase power and the capacity of the electrical panel. The three-phase motor guarantees higher torque and durability than a single-phase motor of the same nominal power.
How to maintain the compressor efficiently?
Drain condensation from the tank weekly (or after each intense session) by opening the drain valve at the bottom. Change the pump unit oil every 500 operating hours or annually. Check the operation of the safety valve every 6 months.
