Asso IV

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.

3-stage pumping unit with gas recovery (Zero Loss version)

  • 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
  • Without maxifilter filter system
  • 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

Electric motor

One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. The 7.5 three-phase electric motor is available on this model kW.

Electrical cabinet

  • ON / OFF switch with motor protection switch.
  • Electromechanical pressure switch that stops the compressor at the final pressure.
  • Drainage of all separators between the individual stages and also of the final separator during compressor operation
  • Timer for automatic condensate drain.
  • Integrated no-load start (automatic drain every time the unit is switched off).
  • 5 liter condensate collection tank, with silencer; capacity of about 3 liters, for the ecological disposal of condensate.
  • Interstage pressure gauges display the working pressure for the individual compression stages. This pressure information allows you to check the tightness of the valves (inlet and outlet) of each stage and to quickly identify potential sources of failure.

Chassis

Silenced chassis made for environments that require a low noise level. The oil level and drain reported outside, the control console equipped with inter-stage pressure gauges, the internal temperature indicator, the alarm presence and incorrect phase sequence, the oil lack alarm and the start-stop commands and manual condensate drain allow easy management and maintenance of the compressor.

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”.
