SIAD VITO 1920

Used compressor SIAD VITO 1920 year 2017


Mechanical configuration and compressor structure


The Used compressor SIAD VITO 1920 year 2017 features a vertical reciprocating design with three compression stages. SIAD Macchine Impianti manufactured this unit in 2017 for demanding industrial applications, such as high-throughput bottling lines.


The compressor uses a crankshaft made of cast iron, which rotates on spherical roller bearings. Steel connecting rods link the crankshaft to ductile iron crossheads. Moreover, a directly mounted flywheel transmits power through V-belts, while an external bearing support prevents shaft deflection caused by belt tension.


In addition, the machine’s construction ensures mechanical stability even under dynamic loads. Consequently, it achieves reliable operation in continuous-duty environments.


Pneumatic circuit and flow regulation

The Used compressor SIAD VITO 1920 year 2017 compresses air using dry-lubricated cylinders mounted on single-chamber distance pieces. Filled PTFE seals ensure durability and chemical resistance. Furthermore, flat-disc or concentric valves regulate intake and discharge flows, and their design allows quick access for maintenance.


The control logic adjusts flow automatically based on final delivery pressure. Therefore, the system supports two or three-step unloading (0–100% or 0–50–100%). When operating under partial load, pneumatically actuated unloader devices open the intake valves to reduce energy consumption.


As a result, the compressor optimizes efficiency without compromising reliability. Similarly, operators benefit from adaptive control in variable process conditions.


Cooling and lubrication systems


The compressor cools its components using a closed-loop water-glycol system. This configuration stabilizes the thermal load during continuous operation. An electrically driven gear pump circulates the lubrication oil throughout the crankcase and the external bearing support.


In fact, the lubrication system includes an in-line heat exchanger, fine filtration, and integrated pressure regulation. Technicians should fill the system with ISO VG 150 mineral oil (e.g., AGIP ACER 150) or, alternatively, a compatible synthetic such as Mobil Rarus 827.


Additionally, the system incorporates temperature sensors and flow monitors that continuously verify operating conditions. Thus, any deviation from normal parameters prompts immediate intervention.


Performance specifications and operating characteristics


The Used compressor SIAD VITO 1920 year 2017 delivers up to 1920 m³/h of free air (FAD) at 40 bar. It draws 265 kW of shaft power at a nominal speed of 750 RPM. The unit compresses air in three stages, and each stage includes a dedicated safety valve.


Operators can expect the compressor to intake air at temperatures from 0 to 40 °C and discharge it at a maximum of 45 °C. Under normal operating conditions, the unit maintains a sound pressure level of 85 ±3 dB(A), assuming a free-field environment
