El Atlas Copco GA 75 es el modelo de 75 kW de la gama de compresores de tornillo con inyecci\u00f3n de aceite GA 30\u207a-90, dise\u00f1ado para instalaciones que planifican su suministro de aire comprimido en funci\u00f3n de una presi\u00f3n de funcionamiento fija y desean un GA 75 que mantenga su valor de consigna a\u00f1o tras a\u00f1o. La gama abarca presiones de trabajo de 7,5, 8,5, 10 y 13 bar. El modelo se presenta en dos variantes: el GA 75, con un caudal de aire libre de hasta 229 l\/s, y el GA 75\u207a, con hasta 257 l\/s con la misma potencia nominal del motor; todas las versiones se suministran como un paquete completo en el que el elemento, el motor, el sistema de refrigeraci\u00f3n y los controles est\u00e1n integrados en una \u00fanica carcasa. La variante \u00abFull Feature\u00bb incorpora adem\u00e1s el secador de refrigerante y el sistema de filtraci\u00f3n en el mismo bastidor.<\/p>\n

Que tenga una velocidad fija no significa que est\u00e9 obsoleta. En el caso de las plantas con una carga base constante, la GA 75 funciona a plena carga durante la mayor parte del turno, que es el punto de funcionamiento en el que la GA 75 convierte la electricidad en aire de la forma m\u00e1s eficiente. El controlador Elektronikon gestiona autom\u00e1ticamente la puesta en marcha, la parada y el apagado en funci\u00f3n de esa carga base.<\/p>\n

El lugar que ocupa el GA 75 en la gama de motores con inyecci\u00f3n de aceite<\/h2>\n

La GA 75 se sit\u00faa en lo m\u00e1s alto de la plataforma GA 30\u207a-90 junto con la GA 90, con las que comparte la misma familia de componentes, el mismo concepto de motor de alta gama y el mismo concepto de servicio. Las plantas lo eligen cuando la demanda de caudal es inferior a 230 l\/s a 7,5 bar o cuando una red de alta presi\u00f3n de 13 bar necesita una m\u00e1quina espec\u00edfica. Las cuatro versiones de presi\u00f3n convierten al GA 75 en una herramienta de planificaci\u00f3n: un solo modelo cubre toda la gama, desde el aire de taller a baja presi\u00f3n hasta el aire de proceso a alta presi\u00f3n. La gama de mayor rendimiento cubre la misma gama con un nivel de caudal superior, por lo que las plantas que necesitan m\u00e1s aire a las mismas presiones pueden seguir optando por el mismo modelo.<\/p>\n

Qu\u00e9 significan \u00abPack\u00bb y \u00abFF\u00bb<\/h3>\n

La denominaci\u00f3n \u00abPack\u00bb abarca el compresor completo: elemento, motor IE4, sistema de lubricaci\u00f3n, circuito de refrigeraci\u00f3n, controlador y cubierta protectora, listo para su conexi\u00f3n a una cadena externa de tratamiento de aire. La gama FF (Full Feature) integra el secador de refrigerante y el sistema de filtraci\u00f3n en el interior del equipo, de modo que el aire suministrado sale de la m\u00e1quina ya secado hasta un punto de roc\u00edo a presi\u00f3n de entre 2 y 3 grados Celsius.<\/p>\n

Ambas ramas utilizan el mismo bastidor de soporte, lo que hace que la planificaci\u00f3n de la instalaci\u00f3n sea id\u00e9ntica, salvo por la mayor profundidad de la cadena de tratamiento.<\/p>\n

The noise level of 73 dB(A) is the A-weighted emission sound pressure level at the work station, determined according to the noise level test code ISO 2151 and the noise measurement standard ISO 9614, with an uncertainty of 3 dB. The reference conditions are an absolute inlet pressure of 1 bar and an intake air temperature of 20 degrees Celsius, and the integrated refrigerant dryer holds a pressure dew point of 2 to 3 degrees Celsius at these conditions. The plus branch posts 71 dB(A) under the same test conditions.<\/p>\n

Dimensiones y peso<\/h3>\n

The Pack measures 1680 mm deep, 1221 mm wide and 1980 mm high, and weighs 1470 kg. The Full Feature branch extends the depth to 2525 mm to house the integrated dryer and filters, keeping width and height unchanged, and weighs 1800 kg. The plus branch weighs 1480 kg as Pack and 1805 kg as Full Feature, with the same envelope. For a 75 kW machine with an integrated treatment chain, the footprint stays within the envelope of a single machine bay, and the canopy opens for service access without extra clearance at the sides.<\/p>\n

El sistema de transmisi\u00f3n Premium<\/h2>\n

Motor IE4 y transmisi\u00f3n directa<\/h3>\n

The GA 75 carries an IE4 efficiency motor, the highest standard efficiency class for this platform, with IP55 protection and insulation class F and a temperature rise class B that keeps the windings well inside their limits. The motor drives the element directly, with no coupling or slippage losses between the two, so the shaft power reaches the compression element unchanged. The non-drive side bearing is greased for life, which removes it from the maintenance schedule entirely.<\/p>\n

Rodamientos h\u00edbridos y filtraci\u00f3n<\/h3>\n

New state-of-the-art hybrid bearings extend the lifetime of the drive train by 33 percent on the GA 55 to GA 90 models, and the GA 75 benefits from this design directly. The oil system runs through a robust spin-on oil filter that removes particles 300 percent smaller than a conventional filter, with an integrated bypass valve and a pressure drop indicator that shows the condition at a glance. The intake side uses a heavy-duty air filter with a maintenance interval of 4,000 hours, which keeps dust and dirt away from the element even in demanding workshop air. On the plus branch, the spin-on oil filter carries an 8,000-hour service interval and the heavy-duty intake filter an 8,000-hour lifetime.<\/p>\n

Caracter\u00edsticas completas: secador y filtros incluidos en el paquete<\/h2>\n

The Full Feature branch turns the GA 75 into a complete air quality station. The refrigerant dryer is sized for the compressor and holds the pressure dew point between 2 and 3 degrees Celsius under all circumstances, preventing freezing at low load.<\/p>\n

Downstream, the filtration stage polishes the air to the quality class the application needs, and the no-loss condensate drain removes water without wasting compressed air. Controlled and monitored by the Elektronikon, the dryer reports its status on the same panel that runs the compressor.<\/p>\n

Punto de roc\u00edo y condensado<\/h3>\n

Condensate from the dryer and the oil separator contains oil traces and must be handled correctly. The electronic no-loss drain discharges it to the condensate management point without releasing air, and the controller supervises the drain so a fault is flagged on the panel instead of going unnoticed. Plants that feed the condensate to an oil-water separator get a clean, compliant discharge path.<\/p>\n

\"Atlas
Atlas Copco GA 75\u207a (1)<\/figcaption><\/figure>\n

Control y conectividad<\/h2>\n

The control principle of the fixed speed platform is built around the load band. The GA 75 loads when the header pressure approaches the lower limit and unloads when it reaches the setpoint, and the Elektronikon keeps the number of these transitions low through intelligent band planning. Between load phases the machine idles rather than stops, which keeps the oil separation stable and avoids the wear that frequent restarts would bring to the motor and the element.<\/p>\n

Elektronikon Touch<\/h3>\n

The Elektronikon Touch controller is the operating center of the GA 75. It manages the motor, guards the pressure band, schedules the service intervals and logs the operating data. The graphic display gives the operators a direct view of the status, and the built-in planning functions protect the machine against unnecessary starts and stops.<\/p>\n

SMARTLINK y OPC UA<\/h3>\n

SMARTLINK remote monitoring is standard and reports the operational parameters of the GA 75 in real time, which lets the service organization plan interventions on data instead of guesswork. OPC UA connectivity integrates the compressor into the production monitoring system as the first compressor manufacturer to offer this protocol in this class, so the machine appears on the factory dashboard alongside the rest of the line.<\/p>\n

Aplicaciones del GA 75<\/h2>\n

The GA 75 covers the classic industrial load spectrum: automotive component plants, metal fabrication with plasma and laser cutting, food and beverage packaging, textile mills and general machinery shops. The 13 bar version serves high-pressure users such as PET blowing preforms, die cutting and laboratory networks, while the 7.5 bar version maximizes the flow for plants that run a single standard header. Workshops that consolidate several aging piston units into one rotary screw machine use the GA 75 as the step that brings the air supply under one monitored, serviceable roof.<\/p>\n

Servicio y asistencia t\u00e9cnica para el GA 75<\/h2>\n

The service points of the GA 75 are grouped for access, and the spin-on filters make the routine services a short planned stop instead of a project. Atlas Copco fluids and lubricants are tailored to the GA 75 with anti-oxidation additives that hold their protective qualities across the service interval, and the Elektronikon tracks the remaining lifetime of every consumable.<\/p>\n

Loading the GA 75 steadily, pairing it with adequate receiver volume and keeping the intake air clean are the three habits that decide the lifetime of the machine.<\/p>\n

The installed base of the GA 75 and its Full Feature branches runs across continents, and Seadweer supports the machine with original spare parts, service kits and technical documentation for every pressure version.<\/p>\n
