The new generation of large portable compressors from Atlas Copco sets high standards - offers compliance with latest European noise and exhaust legislation, improved reliability and durability, and lower cost of ownership.

Three years of research, development and consultation have come to fruition in January 2002, when Atlas Copco Portable Air launched a new range of large portable air compressors.

Comprising 11 models with effective working pressures of 7-25 bar and free air delivery rates of up to 594 l/s, it is thought to be the most technologically advanced range of portable compressors available on the market.

Atlas Copco has designed the new compressors to offer high performance, improved reliability and durability, lower cost of ownership, and to make less of an adverse impact on the environment.


Low emission and low noise

The European launch of the range coincides with the new Exhaust Emission Standard 97/68/EC and the Outdoor Noise Directive 2000/14/EC, which have come into effect in January 2002. It is, however, no coincidence that the new compressors comply with both of these requirements.

Each model is powered by a six-cylinder Mercedes Benz diesel engine, coupled to a single or two-stage compressor unit. Electronic engine management ensures the highest reliability and fuel economy.

Sound dampening panels along the sides and within the door panels create a double insulated wall that contains noise within the machine. A double-walled roof, completes the canopy.

Inlet air enters the unit through stamp die-pressed louvres in the sides of the canopy and exhaust gases are emitted through the roof. To prevent water from entering the unit, the roof-mounted exhaust louvres open only when the engine is running.

Zincor treatment and a powdercoat paint finish provide the canopy with a durable and corrosion resistant surface that can withstand the tough conditions the sets are designed to operate in.

Spillage free to safeguard the environment

A totally new design concept is the sealed compressor frame. This prevents any fluid leakage that might occur from within the unit from spilling onto the ground. Instead, the fluid collects in the frame, where it can be piped away or drained into a suitable container.

The engine oil, coolant and compressor oil drains are linked to a central point at the rear of the unit. Individual ball valves with safety plugs help to prevent accidental spillages occurring when the compressor is serviced.

Easy to operate

Operators can check on the operating status using a combination of analogue gauges and digital readouts on the control panel.

The digital panel also displays warning and shutdown messages if it detects abnormal conditions. There is a choice of twelve languages in which these messages appear, and the option of viewing numerical readings in imperial or metric units. An audible alarm and warning light are also included to alert the operator of the warnings or shutdowns.

Simple servicing

All service points are within easy reach so that the compressor spends less time in the workshop and more time delivering compressed air. The result is lower ownership costs.

Extra wide double doors on each side of the canopy provide access to most of the components for servicing. The compressor air filter and elements, various valves and the vessel oil filling neck can be reached through service doors at the front. Two doors at the rear provide full access to the cooler assembly for cleaning. And a hinged lockable panel on the roof allows the compressor oil/water separator to be replaced without removing any other panels.

Fuel tanks are located below the main frame. This keeps them away from the hot engine areas and improves access to the engine. They can be cleaned in-situ or removed from the unit for cleaning.

Handling with care

In addition to the conventional lifting eye at the top of the unit, Atlas Copco has included forklift slots under the frame. Both ensure that the compressor can be lifted safely and properly balanced.

Other safety features include the option of ABS brake systems for road homologated units.


Atlas Copco expects to launch the new range in non-EU markets during the first half of 2002.
