KFAS H twin-shaft centrifugal air and nitrogen duty references — Kaifeng Air Separation Group (KFAS)

Datasheet

Product overview

Power: 625 kW shaft power, reference air duty · Pressure: 0.098 to 0.70 MPa absolute, air duty · Flow: 125 m³/min, reference air duty

The H route is KFAS's twin-shaft centrifugal architecture, with individual air and nitrogen selections in the official engineering table. The two shaft speeds listed for a reference describe the compressor arrangement; they are not two alternative supply frequencies or motor speeds.

H125-7/0.98 code 6083 is the air example: 125 m³/min, 0.098 MPa absolute suction, 0.70 MPa absolute discharge and 625 kW shaft power. H130-9/1.04 code 6130 is the nitrogen example: 130 m³/min, 0.104 MPa absolute suction, 0.90 MPa absolute discharge and 725 kW shaft power. Both references list 20,174/24,656 rpm. Keep the gas and absolute-pressure basis attached to each model/code; air duty cannot qualify the nitrogen machine, nor do either of these entries establish oxygen suitability.

Supply gas composition and temperature, actual suction range, flow reference conditions, normal/minimum/peak demand and downstream pressure. Ask for a selected map, driver rating, performance-test conditions and permitted operating range. The table's m³/min heading does not establish Nm³/min or a delivery guarantee for a present order. Shaft power remains separate from the installed motor and complete package electrical input.

For integration with an air-separation plant, agree anti-surge response, trip/permissive ownership, package-to-DCS signals, cooler/water duty and electrical starting. Request foundation and lifting drawings, maintenance access, monitoring/test records and spare-part support for the actual configuration. The original KFAS centrifugal portfolio image is shared family context, not a photograph of the named H air or nitrogen reference. Confirm the specific machine through the technical offer and as-built documentation.
