DFV(G) oil-free screw compressors — Guangdong Ecoair / Aigao Equipment (Foshan Sanshui)

Datasheet

Product overview

Power: 37–500 kW, family table · Pressure: 0.75, 0.85 or 1.0 MPa where rated · Flow: 75 kW: 13.0 / 10.7 / 8.9 m³/min by pressure

Ecoair describes DFV(G) as oil-free screw compression using 4:6 rotor geometry, timing gears and non-contact rotor engagement. The package has a coupled motor/airend arrangement, modular main components, HMI control and cooling between compression stages. The original image illustrates the dry oil-free family; identify the exact model and A/W or W suffix on the offer rather than treating a family photograph as an exact configuration drawing.

The family table spans 37–500 kW and lists volumetric flow at 0.75, 0.85 and 1.0 MPa where a value is provided. DFV(G)M75A/W is 75 kW with 13.0, 10.7 and 8.9 m³/min at those respective pressures. It has a DN65 outlet, 2,950 × 1,850 × 1,750 mm dimensions and a 2,600 kg mass. DFV(G)M132A/W is 132 kW with 25.3, 23.0 and 20.2 m³/min at the same three pressures and a DN80 outlet. A slash in another model's pressure column is not a published duty point and must not be filled by interpolation.

The lower table block gives 380 V; larger entries include different voltage possibilities. Confirm the selected unit's phase, frequency, starting arrangement and cooling utility requirements. Specify acceptable total oil, pressure dew point and particles at the point of use, together with dryer/filter arrangement and a model-specific test or certificate scope. The manufacturer's Class 0 wording alone does not establish the certificate applicability to the purchased unit or delivered air system.
