UNIGY UNI variable-speed twin-screw industrial air compressors — UNIGY — Luoyang industrial gas compressors

Datasheet

Product overview

Power: 2–400 kW — family envelope · Pressure: 0.7–1.3 MPa — family envelope · Flow: 0.5–70 m³/min — family envelope

The UNI screw-air range is separate from UNIGY's oil-free reciprocating process-gas catalog. Its UNI2-400VSD page gives a family envelope of 2–400 kW, 0.5–70 m³/min and 0.7–1.3 MPa. These are independently listed family limits, not paired power/flow/pressure points for one machine. Later body text also names UNI2-250KWVSD, so obtain the exact offered model and current revision-controlled data before selection.

The manufacturer describes a twin-screw airend, variable-frequency control, bearings and sealing. Request confirmation of the actual lubrication system, drive, electrical supply/frequency, usable control range, pressure band, low-load behavior, cooling/ventilation and measured whole-package input. Source marketing statements about efficiency, starting current and savings are not acceptance guarantees for the buyer's demand profile.

For an industrial air room, state pressure and simultaneous airflow at the process, peak and low-load periods, air-quality target, site ambient/altitude, noise location and maintenance access. Agree receiver, dryer, filtration and condensate handling separately, with commissioning, protection/control interfaces and spare parts. Class 0 claims on other UNIGY oil-free product pages do not establish this screw family's air-purity certification. If a purity class is required, obtain appropriate exact-model and downstream air-system evidence at agreed test conditions.
