Atlas Copco GA 30 (FF TM 30⁺) Oil-Injected Rotary Screw Air Compressor

Description

The Atlas Copco GA 30 is the 30 kW fixed speed screw compressor of the oil-injected range, and it reaches the market through two official branches. The GA 30 tops the compact GA 11+-30 series as a WorkPlace machine that integrates the refrigerant dryer on request, while the GA 30+ opens the large GA 30+-90 platform as its base model with Pack and Full Feature builds.

The GA 30 delivers up to 93.3 l/s and the GA 30+ up to 99 l/s at 7.5 bar, both on a 30 kW / 40 hp motor rating. One model therefore covers two installation strategies: the sealed 790 mm wide WorkPlace box for tight machine rooms, and the 890 mm wide platform frame for plants that plan around the GA 37 to GA 90 family.

Both branches carry the same pressure ladder up to 13 bar, the same Elektronikon control philosophy and the same oil-injected element principle. The sections below keep the two branches side by side, because the right choice depends on the room the plant can give the machine and the air treatment it wants inside the canopy.

Where the GA 30 Fits in the Oil-Injected Range

The GA 30 sits at the foundation of the fixed speed platform. Inside the compact GA 11+-30 series it is the flagship above the GA 26+, and on the large platform it enters as the GA 30+ one step below the GA 37. Plants choose the WorkPlace branch when floor area, noise and installation speed drive the project, and the GA 30+ when the compressor must join a fleet of large GA machines with shared service logic. The four pressure versions of each branch turn the model into a planning tool that covers 7.5 bar workshop air up to 13 bar high-pressure air without changing the model choice.

What WorkPlace Standard, FF and Pack Mean

The WorkPlace build comes as a Standard build with the compressor, cooling system and controller inside the sound-proofed canopy, and as an FF build that adds the refrigerant dryer and the condensate management inside the same enclosure. The FF build leaves the machine with dry air at a pressure dew point of 3 degrees Celsius, ready for the distribution network.

The GA 30+ uses the Pack and Full Feature naming of the large platform: the Pack is the complete compressor ready for an external treatment chain, while the Full Feature build integrates the dryer and filtration into the 1810 mm deep frame.

Technical Specifications of the GA 30

The table below condenses the two branches into their headline figures:

WorkPlace 50 Hz Pressure Versions

Unit performance of the WorkPlace branch is specified per pressure version, with the maximum working pressure of the Standard build quoted next to the reduced value of the FF build, whose dryer takes a small share of the pressure. The reference conditions are an absolute inlet pressure of 1 bar and an intake air temperature of 20 degrees Celsius:

GA 30+ 50 Hz Pressure Versions

The plus branch publishes its FAD in the units of the large platform leaflet, measured according to ISO 1217 with the effective working pressures of 7, 8, 9.5 and 12.5 bar(e):

GA 30+ 60 Hz Pressure Versions

The 60 Hz versions quote their pressure variants in psig and their performance is measured according to ISO 1217, annex E, under the same reference conditions:

The noise figures differ between the branches in an interesting way: the WorkPlace canopy posts 70 dB(A) on every pressure version, while the GA 30+ holds 66 dB(A) across the whole ladder. Both are A-weighted emission sound pressure levels at the work station determined according to ISO 2151 with an uncertainty of 3 dB. The lower figure of the GA 30+ comes from the low noise fan of the large platform, and both machines stay at levels that allow installation close to production areas.

Dimensions and Weight

The WorkPlace branch measures 1267 mm deep, 790 mm wide and 1590 mm high, and weighs 579 kg as a Standard build and 634 kg as an FF build. The GA 30+ Pack measures 1310 mm deep, 890 mm wide and 1790 mm high and weighs 626 kg, while its Full Feature build extends the depth to 1810 mm to house the dryer and weighs 796 kg.

At 60 Hz the GA 30+ weighs 643 kg as a Pack and 813 kg as a Full Feature. All figures keep the machine inside a single-person transport and a standard machine room, and the 790 mm width of the WorkPlace branch fits corridors that exclude almost every other industrial compressor.

Drive System and Motors

WorkPlace Motor, Gearbox and Cabinet

The WorkPlace branch drives its element through the core Atlas Copco drive chain with a high-efficiency gearbox, paired with IE3 and IE4 efficiency motors whose motor bearings are grease-lubricated for life and leave the maintenance schedule entirely. The upgraded flow path of this series lifted the free air delivery of the model noticeably against the previous generation, and the machine meets Grade 1 of the GB19153-2019 energy efficiency standard.

The electrical cabinet is force-cooled to keep the component temperature down and extend electronics lifetime, and the innovative fan design reduces the fan power draw while controlling the noise emission of the machine.

The GA 30⁺ Drive of the Large Platform

The GA 30⁺ carries the maintenance-free drive system of the GA 30⁺-90 family: totally enclosed, protected against dirt and dust, with no coupling and no slippage losses between the motor and the element. The motor is an IE4 / NEMA Super Premium efficiency unit with IP55 protection, insulation class F and a temperature rise class B, and its drive side bearings are oil-lubricated for continuous operation in harsh environments.

The machine runs in ambient conditions up to 46 degrees Celsius as standard, and a high ambient version extends this to 55 degrees Celsius. The oil side runs through a robust spin-on oil filter that removes particles 300 percent smaller than a conventional filter, with an integrated bypass valve, and the heavy-duty air intake filter removes 99.9 percent of dirt particles down to 3 microns.

Control and Air Treatment

Elektronikon and Multi-Unit Control

Both branches run on the Elektronikon controller family. The WorkPlace branch is operated from the touchscreen controller with built-in smart algorithms that optimize the system pressure and lower total energy consumption, with remote start and stop, alarm output, maintenance scheduling and network diagnostics included, and SMARTLINK remote monitoring on board.

The controller holds two pressure bands that can be switched manually or automatically, so a plant that drops its header pressure at night runs the second band instead of wasting energy. The Delayed Second Stop function keeps the motor off until the pressure really calls for it, and an optional integrated compressor controller coordinates installations of two, four or six machines.

Integrated Dryer and Air Quality

The FF and Full Feature builds integrate the refrigerant dryer with a counterflow heat exchanger and an integrated water separator, regulated automatically against the compressor load, and hold a pressure dew point of 3 degrees Celsius. The aftercooler removes most of the moisture ahead of the dryer, and the electronic no-loss drain discharges condensate without releasing compressed air.

The dryer uses the environmentally friendly R134a refrigerant, and with the built-in Class 1 internal filter the delivered air reaches a residual oil content of 0.01 ppm. On the GA 30+ the UD+ filter option reaches air quality Class 1.4.2 according to ISO 8573-1:2010 with a single filter stage.

Energy Recovery and Efficiency

During compression up to 90 percent of the electrical input of the machine turns into heat, and the integrated energy recovery system returns up to 75 percent of that input power as hot water without any impact on the compressor operation. The recovered heat feeds auxiliary heating, industrial processes, laundries and sanitation facilities, which shortens the payback period of the whole installation. Combined with the dual pressure band and the delayed second stop of the controller, the GA 30 converts a fixed speed machine into an efficient network node instead of a constant-loss idler.

Applications of the GA 30

The GA 30 covers the daily duties of workshops and production plants: machinery shops, packaging and filling lines, laboratories and service businesses that draw compressed air all day. The 10.5 and 13 bar versions serve high-pressure users such as pressure testing benches and die cutting, while the 7.5 bar version maximizes the flow for a single standard header.

Plants that currently run an aging piston compressor move to this machine for the rotary screw efficiency, the sealed drive train and the low noise of the WorkPlace canopy. Plants that plan fleet growth choose the GA 30+ branch, because it shares the frame, the service concept and the controller logic with the GA 37 and the machines above it.

Service and Support Around the GA 30

The service points of both branches are grouped for access, and the spin-on filters turn the routine services into a short planned stop. The Elektronikon tracks the remaining lifetime of every consumable and reports the maintenance schedule before a component reaches its limit, and SMARTLINK keeps the service organization informed remotely. After registration the machine carries a 5-year factory warranty or 24,000 hours of actual operation, whichever comes first.

Options such as the high-temperature model for 55 degrees Celsius, food-grade oil, synthetic oil, a dryer bypass and on-site witness testing adapt the machine to special environments. Plants that outgrow the GA 30 step into the GA 37 on the same platform logic. Seadweer supports the GA 30 and both of its branches with original spare parts, service kits and technical documentation for every pressure version.
