Oil-free oxygen reciprocating compressors — Anshan Libang Compressor

Datasheet

Product overview

Power: 5.5 or 3.0 kW, distinct 30 m³/h models · Pressure: Selected rows: 0.15 or 0.4 MPa inlet; 1.0 MPa outlet · Flow: 30 m³/h, selected models; confirm basis

Libang describes an oil-free gas-side oxygen reciprocating range for oxygen-production, circulation and industrial oxygen duties. The stated family suction envelope is 0–1 MPa(G), with discharge up to 5 MPa(G). Its gas-contact design uses self-lubricating rings and rod packing; the bearing lubrication remains separate from the medium. The manufacturer explicitly calls for cleaning and degreasing of oxygen-contact components and piping during manufacturing and installation. Agree the supplied cleanliness specification and preservation with qualified project personnel.

The original oxygen table labels flow in m³/h and illustrates why inlet pressure belongs on an enquiry. VWZT-30/1.5-10 gives 30 m³/h with 0.15 MPa inlet, 1.0 MPa outlet and 5.5 kW; its dimensions are 1,300 × 920 × 1,000 mm and mass 262 kg. ZWZT-30/4-10 gives 30 m³/h with 0.4 MPa inlet, 1.0 MPa outlet and 3.0 kW; the table lists 860 × 830 × 1,000 mm and 120 kg. These are different models and configurations. Confirm pressure and flow reference conditions before comparing them or selecting for another oxygen-source pressure.

Provide the oxygen concentration and impurities, source-pressure range, inlet temperature, outlet duty and destination use. Request oxygen-service materials and cleanliness records, actual performance and leakage-test conditions, controls/interlocks, treatment/storage scope and installation documents. Applications named on the manufacturer's page do not by themselves establish the purchased unit's medical or destination regulatory approval. Match the current documents to the exact package and end use.
