Ace I

Simplicity comes standard.

Imagine having a compressor capable of great performance and endowed with extraordinary solidity. What would all this be without absolute simplicity in managing it?
We believe that innovation is for this: to make everything simpler.

2-stage high pressure pumping unit.

  • Monobloc in aluminum,
  • Crankshaft in forged steel
  • with forced lubrication on 2nd and 3rd stage cylinders by gear pump
  • Oil filtration.
  • Oversized interstage cooling pipes
  • Double final separator
  • Forged aluminum connecting rods
  • Main roller bearings
  • Roller connecting rod bearings
  • 2nd stage cylinder in aluminum with hard nicasil coating
  • 2nd and 3rd stage slide guide cylinders in aluminum with hard nicasil coating
  • 3rd stage cylinder in special treated steel.
  • Stainless steel intake and exhaust valves
  • Interstage cooling pipes in stainless steel
  • Separator after the 2nd and 3rd stage
  • Safety valves after each stage
  • Oil level sensor


The purity of the air is achieved.

The Maxifilter purification system enables reliable treatment of breathing air and technical gases according to DIN EN 12021¹ when using original filter cartridges. Placed after the last compressor separator and before the pressure maintenance valve, it has the separator after the 2nd and 3rd stage to create a first, fundamental barrier against humidity. The filtering capacity with inlet air at 20 ° C and 200bar is 620 m³.


Electric motor

One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. The 4 to 5 three-phase electric motor is available on this model, 5 kW.



Essential and compact, this frame is designed to facilitate portability. The tilting motor-holder plate guarantees the constant tension of the V-belt. The protective casing in thermo-formed material conveys the cooling air on the cylinders and on the inter-stage pipes. This guarantees a high compression efficiency.


The best for you,
the best for your work.

The Booster compressors prove it: the best possible machine is the one that meets the specific needs of “that” customer, customizing the response in terms of reliability and performance.
Whether we are talking about air, helium, hydrogen, nitrogen, the customer comes before the solution: this is our “creed”.
