Atlas Copco GA 160 (FF 160⁺) Oil-injected Air Compressor

The Atlas Copco GA 160 is a fixed-speed oil-injected rotary screw compressor rated at 160 kW, offered in four factory versions covering working pressures from 5.5 bar to 10 bar. It opens the GA 160+-250 range and suits plants whose air demand stays level across shifts. This page collects the full technical data of the machine together with the design and service details that matter when selecting a compressor in this class.

Each unit ships as one complete package on an oil-containing frame, so no separate foundation is needed. The element, gear transmission, coolers, motor, and controller all sit inside a sound-reduced canopy, and ducting can be arranged with flexibility once the machine is positioned.

Dimensiones

Capacity figures are measured according to ISO 1217, Annex C and E, Edition 4 (2009), at an absolute inlet pressure of 1 bar and an intake temperature of 20°C. Each pressure version is rated at its own reference point: the 5.5 bar version at 5 bar, the 7.5 bar version at 7 bar, the 8.5 bar version at 8 bar, and the 10 bar version at 9.5 bar. Noise values are the A-weighted sound pressure level at the work station.

Screw Element and Cooling Module

Air compression starts in a state-of-the-art screw element. Its patented asymmetric rotor profile works with carefully selected bearings, so wear stays low over thousands of running hours. That design has been proven across a large installed base and gives the GA 160 a steady output curve year after year.

Heat is handled by a cooling module that separates the oil cooler from the aftercooler, which keeps each heat exchanger working at its best efficiency point. Axial cooling fans are driven by their own TEFC electric motors with IP55 protection. The layout also keeps the sound level at the work station down to 78 dB(A) at 50 Hz.

Gear Transmission and Service Access

The screw element is driven through a gear transmission that is totally enclosed and protected against dirt and dust. It holds the element in its optimal working range and needs no maintenance over the life of the machine. A Bowex coupling absorbs the thrust load, which protects the drivetrain when the compressor cycles between loading and unloading.

Service work is planned around easy access. Large opening doors give a clear path to every service point, and a unique sliding system pulls the oil coolers out for cleaning. Consumables are chosen for long lifetime, and Roto-Xtend Duty fluid with an 8000h change interval is available for sites that want to stretch the time between stops.

Air Intake and Condensate Handling

A superior air intake filter removes 99.9% of dirt particles down to 3 μm before they can reach the element or the oil. Because the fine filter then carries a much lighter dust load, its element lasts about twice as long without any loss of filtration efficiency.

Moisture is dealt with inside the package. An integrated water separator with an electronic drain removes 100% of the condensate that drops out after compression, so there is no need to plumb a separate separator at start-up.

Elektronikon Control

The GA 160 is managed by the Elektronikon controller. Its high resolution color display shows running conditions in plain readings, and clear icons keep navigation quick. Warning indications, maintenance scheduling, and online visualization of the machine status are all built in, with support for 31 languages.

For plants that want to trim system pressure without losing margin, the optional ES system controller watches the whole machine room from one point. Dual pressure set-point and the Delayed Second Stop function keep the drive motor off whenever the network pressure still holds, which trims energy use in low-demand periods. Remote monitoring runs over Ethernet as standard, and a mobile app extends supervision to phones and tablets.

Recuperación de energía

Most of the electrical energy that goes into compression leaves the package as heat. An integrated energy recovery system can return up to 94% of the shaft power as useful heat, delivered as hot water at 85°C to 90°C (185°F to 194°F). The main heat exchanger module is built into the compressor, so tying it into an existing water circuit for space heating, showers, or process use takes a modest installation effort.

Simpler ducting-based recovery is also possible. Flexible ducting directs warmed cooling air toward workshops or storage areas, and louver flaps vent the warm air outside when the season changes. Motorized, thermostatically controlled louvers give full command of the heating airflow.

Where the GA 160 Fits

With four pressure versions and a 160 kW motor, the GA 160 covers general manufacturing, injection molding, textile plants, and workshops that need a continuous baseline of compressed air. The 10 bar version adds headroom for installations that run pneumatic controls or compact tools at higher settings. Larger sites in the same family can step up to the Compresor de aire con inyección de aceite Atlas Copco GA 250, which shares the same design platform at 250 kW.

GA 160 FAQ

What pressure versions does the GA 160 come in?

At 50 Hz there are four versions: 5.5 bar, 7.5 bar, 8.5 bar, and 10 bar. At 60 Hz the versions run from 75 psi to 150 psi, all rated at 215 hp.

Does the GA 160 need a special foundation?

No. An oil-containing frame is part of the standard package, so the unit stands on a flat floor without a separate foundation.

How long can the service intervals be stretched?

Consumables are selected for long lifetime, and the optional Roto-Xtend Duty fluid extends the fluid change interval to 8000 hours.

Is the GA 160 suitable for dusty workshops?

Yes. The intake filter captures 99.9% of particles larger than 3 μm, and the enclosed gear transmission keeps dust away from the drivetrain.

What happens to the condensate?

The integrated water separator with electronic drain removes 100% of the condensate formed inside the package.

Can the heat from the GA 160 be reused?

Yes. Up to 94% of the shaft power can be recovered as hot water at 85°C to 90°C, or the warm cooling air can be ducted to heat adjacent spaces.
