The Atlas Copco GA 45 is the 45 kW (60 hp) fixed speed oil-injected screw compressor in the GA 30+-90 series. Two branches share the platform: the GA 45 itself and the GA 45+ build with its larger compression element. Each comes as a Pack or as a Full Feature unit with the dryer factory fitted. Pressure versions cover 7.5, 8.5, 10, and 13 bar at 50 Hz, while 60 Hz plants select among 100, 125, 150, and 175 psig nameplates. Every figure from the official tables appears below, so a buyer can match branch and pressure version to the duty before requesting a quotation.<\/p>\n

Delivery is a single pre-assembled package: screw element, gear transmission, coolers, oil system, and the Elektronikon controller are tested together on one base frame. The machine needs only a level floor, power, and an air outlet to start producing.<\/p>\n

Especifica\u00e7\u00f5es t\u00e9cnicas<\/h2>\n

Capacity follows ISO 1217, Annex C, Edition 4:2009. FAD is referenced to 7 bar on the 7.5 bar build and 8 bar on the 8.5 bar build. The 10 bar build references 9.5 bar, and the 13 bar build 12.5 bar.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Every version draws on the same 45 kW (60 hp) motor. At 50 Hz the Pack weighs 692 kg (1526 lb) and the Full Feature build 900 kg (1984 lb). The plus branch carries 808 kg and 978 kg at the same stages. Sound readings are taken at the work station according to ISO 2151 and ISO 9614, with a 3 dB(A) uncertainty, and both branches read 68 dB(A).<\/p>\n

60 Hz Versions<\/h2>\n

For 60 Hz markets the same two branches appear under psig nameplates, measured per ISO 1217 with the footnotes and reference conditions of the 50 Hz tables.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Motor rating and sound level stay identical across the two supplies. The 60 Hz packages weigh slightly more: the base Pack at 745 kg (1642 lb), its Full Feature build at 915 kg (2017 lb). Installation drawings should follow the frequency actually ordered.<\/p>\n

The GA 45+ Branch<\/h2>\n

Behind the unchanged 45 kW (60 hp) motor rating, the plus branch mounts a larger compression element. Flow climbs from 138 to 151 l\/s (293 to 320 cfm) on the 7.5 bar build. On the 10 bar build it rises from 119 to 131 l\/s (253 to 278 cfm). On the 13 bar build both branches print 105 l\/s, so the plus advantage concentrates in the lower and middle pressure versions. The branch weighs 116 kg more as a Pack and 78 kg more with Full Feature, the trade-off for the bigger element and its oil circuit.<\/p>\n

Plants that draw near-full load around the clock get the widest flow band of the 45 kW class from this build. The acoustic package keeps the work station figure at 68 dB(A) on every version.<\/p>\n

Pack and Full Feature Builds<\/h2>\n

Each branch is offered as a Pack or as a Full Feature unit. The Pack occupies 1310 \u00d7 890 \u00d7 1790 mm (depth \u00d7 width \u00d7 height) and rolls into position without a special foundation. Choosing Full Feature extends the depth to 1810 mm. The integrated refrigerant dryer, its filtration, and the electronic condensate drain ride on the same frame, wired and piped before they leave the factory. The dryer holds a pressure dewpoint of 2\u00b0C to 3\u00b0C (36\u00b0F to 37\u00b0F) at reference conditions.<\/p>\n

A built-in energy recovery module is available in the series, routing compression heat toward water heating or process duty instead of the cooler exhaust.<\/p>\n

Compact Canopy and Single-Side Service<\/h2>\n

The canopy is just 890 mm wide on both branches, which lets the machine travel standard doorways and park against a wall or in a row of units. Acoustic material lines every panel, and daily checks plus routine service points gather behind panels on one side at standing height.<\/p>\n

An enclosed gear train connects the motor to the element without belts to tension or couplings to align. One synthetic oil circuit lubricates, seals, and cools in a single pass. The layout keeps the 45 kW class usable in cramped utility rooms where larger frames cannot go.<\/p>\n

Where the GA 45 Fits<\/h2>\n

The 7.5 bar and 8.5 bar builds serve textiles, blowing, and general plant air. The 10 bar build matches assembly lines and packaging. The 13 bar build carries injection molding and high-pressure tool networks. Fixed speed logic rewards sites with level consumption. Operations whose demand swings between shifts should compare the variable speed route, for example the Compressor de ar com inje\u00e7\u00e3o de \u00f3leo Atlas Copco GA 250<\/a> range and the GA 45 VSD of the same series.<\/p>\n

GA 45 FAQ<\/h2>\n

How do the two branches differ?<\/strong><\/p>\n

The plus branch fits a bigger element behind the same 45 kW (60 hp) motor. Output rises from 138 to 151 l\/s on the 7.5 bar build, while on 13 bar both branches deliver 105 l\/s. Sound stays at 68 dB(A) either way.<\/p>\n

Which pressure version fits my plant?<\/strong><\/p>\n

Pick the lowest version that covers the highest pressure consumer on site. Options run 7.5, 8.5, 10, or 13 bar at 50 Hz, or 100, 125, 150, and 175 psig at 60 Hz.<\/p>\n

How much air does the family produce?<\/strong><\/p>\n

Across branches and pressure versions the 50 Hz range spans 105 to 151 l\/s (222 to 320 cfm), referenced to ISO 1217, Annex C.<\/p>\n

What does Full Feature include?<\/strong><\/p>\n

An integrated refrigerant dryer, filtration, and an electronic condensate drain, factory assembled on the same frame. Depth grows from 1310 to 1810 mm while the 890 mm width and 1790 mm height stay put.<\/p>\n

What does the package weigh?<\/strong><\/p>\n

At 50 Hz the Pack weighs 692 kg and Full Feature 900 kg; the plus builds carry 808 kg and 978 kg. The 60 Hz base packages weigh 745 kg and 915 kg.<\/p>\n

Can the machine give its heat back?<\/strong><\/p>\n

Yes. A built-in energy recovery module is offered in the series and routes compression heat toward water heating or process duty instead of venting it.<\/p>","protected":false},"excerpt":{"rendered":"
