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 machineâs 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
(0â100% or 0â50â100%). 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
