Power range150–4000 kW
Capacity / flow40–500 m³/min
Pressure / vacuum0.2–1.0 MPa
ConfigurationThree-stage oil-free centrifugal
Five engineering advantages
100% oil-free air path
100% oil-free air path is integrated into the published ZGT platform to improve stable, efficient operation under the intended duty.
Working principle and core architecture
Air passes through three centrifugal compression stages. Intercoolers reduce air temperature between stages, while the inlet guide vane regulates capacity and the gearbox maintains the required impeller speed.

Frequently asked questions
ZGT Oil-Free Centrifugal Air Compressor is The ZGT platform supplies 40–500 m³/min of oil-free compressed air through staged centrifugal compression, intercooling and linear inlet guide vane control.
Base selection on measured normal and peak demand, required pressure or vacuum, annual operating hours, electricity supply, cooling conditions, air-quality requirements and installation environment.
No unconditional percentage is guaranteed. Published comparisons depend on baseline equipment, load profile and operating conditions. A project assessment is required.
Provide the application, required capacity, pressure or vacuum, normal and peak load, operating hours, voltage and frequency, ambient conditions, cooling utilities and delivery country.
