Used Siad Auxiliary Equipment for Sale

Siad Macchine Impianti traces its roots to Bergamo, Italy, where the Siad Group was established in 1927 — its very first product being an acetylene compressor. Over nearly a century the engineering division grew into a world-recognized manufacturer, supplying more than 5,000 reciprocating process gas and air compressors to customers across every continent. Today the company remains a family-owned enterprise with over 2,200 employees and annual group revenues exceeding one billion dollars, with manufacturing facilities in Italy and China and certified service centers spanning Europe, the Americas, the Middle East, and Asia.

The flagship product line for the used market is the Tempo series of oil-free, high-pressure piston compressors purpose-built for PET and PLA bottle blowing. The Tempo 950 — one of the most widely traded models on the secondary market — is a three-stage, glycol-cooled piston compressor delivering up to 950 m³/h at a maximum discharge pressure of 42 bar, with all air-contact pipework in stainless steel to guarantee air purity. Siad has since evolved the platform into the Tempo 2 series and, more recently, the Vito and Vito Next ranges, which add variable-speed drive capability and the SiadMI4U remote monitoring system. The company also manufactures API 618 reciprocating compressors for process gases, instrument air packages, and nitrogen generation packages.

Siad Macchine Impianti's high-pressure air compressors are central to the food and beverage packaging industry, where they power stretch blow-molding lines for PET and rPET bottles. The same oil-free technology serves the cosmetics, chemical, and pharmaceutical sectors wherever contamination-free compressed air is critical. The broader reciprocating compressor range reaches into refining, petrochemical, chemical processing, energy and power generation, LNG, aerospace, and industrial gas production — making Siad equipment a fixture across heavy process industries worldwide.

Buyers seeking used Siad high-pressure compressors are drawn first by the machines' robust, heavy-duty construction: the oil-free three-stage piston design, vibration-isolated skid mounting, and stainless-steel air lines translate into long service intervals and low lifecycle costs. Siad's status as an OEM means original spare parts remain available globally, supporting straightforward maintenance even on older Tempo-series units. The compressors are known to accumulate tens of thousands of operating hours before major overhaul, and fully refurbished examples regularly re-enter service — making the used market an attractive, cost-effective route to proven Italian-engineered compression capacity.
