MSG Centac centrifugal air compressors — Ingersoll Rand (China) Industrial Equipment (Wujiang)

Datasheet

Product overview

Pressure: Model-specific envelope · Flow: See model envelopes

MSG Centac is Ingersoll Rand's oil-free centrifugal air-compressor family. The dated 2025 China brochure provides model selection envelopes, with performance dependent on inlet conditions. This route is separate from the MSG process-compressor family; a Wujiang MSG manufacturing-centre reference alone does not establish the origin of the selected Centac package.

The brochure lists C400 at 40–67 m³/min and 3.4–8.6 barg; C700 at 55–130 m³/min and 3.1–10.3 barg; and 3CII at 185–267 m³/min and 3.1–10.3 barg. Flow and pressure are separate family ranges, not guaranteed paired duties. The original webpage contains different envelope values, so this page uses the dated brochure consistently and requires the current offer's performance map. Do not combine maximum flow and maximum pressure into an invented operating point.

Provide actual inlet pressure, temperature and humidity, cooling-water inlet conditions, required discharge pressure and minimum/normal/peak demand. Ask for the selected performance curve, minimum stable operation, surge-control and blow-off behaviour, driver/starting requirements and total package input. A station's low-demand periods and trim-machine sequence affect the selection as much as maximum production demand.

The brochure describes integrated cooling/separation, accessible components and controller connectivity including MODBUS. Agree those interfaces and the delivered cooling/treatment boundary, dryer and filter losses, air-quality limits at the process sampling point, foundation and lifting access, test/witness conditions, commissioning and service responsibilities. Obtain any required model-specific air-quality or destination conformity documents. The original Centac brochure illustration depicts the family rather than a buyer's completed installation.
