Atlas Copco machines focus on durability.

The two latest additions to Atlas Copco's Compressor Technique business are designed to take durability to a new level. Featuring a new canopy construction on both its XAS 185 JD7 HardHat portable compressor and QAS 24 mobile generator, Atlas Copco said the new machine designs are engineered to stand up to the demands of the rental markets.

Featured on the new XAS 185 JD7 HardHat portable compressor is Atlas Copco's HardHat canopy, which was initially launched to the European marketplace two years earlier. The new HardHat design uses a polyethylene shell that the company said is capable of withstanding the harshest environments, minimizing the damage brought on by daily bumps and bangs--making it an ideal machine for the weekend renter.

Engineered to be dent resistant, as well as rust, corrosion, fade, UV, temperature and crack resistant, the XAS 185 JD7 HardHat portable compressor provides users a higher resale value based on the appearance of the machine and also lowers the cost of ownership because side panels and canopy do not need replacing or painting, said Atlas Copco. For additional damage protection, all of the XAS 185 JD7 compressor's controls, lights and air couplers are tucked away at the rear of the machine.

Housed beneath the XAS 185 JD7 compressor's HardHat canopy is a 2.44 L four-cylinder John Deere 4024T diesel engine rated 49 hp at 2750 rpm. The engine is Tier 2 compliant, direct injected and turbo-charged. It drives an Atlas Copco rotary screw air-end, which generates 185 cfm and has a 3.18 gal. air receiver. Typical applications for this 185 cfm machine include powering sandblasting and pneumatic tools such as chipping hammers, jackhammers, nut runners, grinding tools and rammers.

The compressor, which incorporates a 25 gal. fuel tank, weighs 2330 lb. (wet) and is 125 in. long x 64 in. wide x 61 in. high, which the company said allows it to be towed behind a midsized SUV and maneuvered on a congested work site such as road construction projects. A simplified control panel is also integrated into the unit, making it easier for novice users to operate, Atlas Copco said.

Atlas Copco began offering the HardHat canopy on the XAS 185 JD7 compressor in February. The unit is manufactured in Rock Hill, S.C. A steel canopy version is also available.

Also targeting rental applications is Atlas Copco's new QAX 24 mobile generator. The gen-set has a power output of 19.2 kW and is driven by a 2.33 L three-cylinder Deutz F3M 2011F diesel engine rated 31.7 at 1800 rpm. This Tier 2 mechanical engine is naturally aspirated and has direct fuel injection. It is coupled with a Stamford BCI 184 El alternator with 12 leads, Class H insulation and IP23 protection. Output is 24 kVA at 1800 rpm and 60 Hz.

A new clamshell canopy constructed of Zincor steel provides protection for the QAX 24 gen-set and the unit also has a powder-coat finish designed to protect against corrosion and fading. The canopy swings open to provide access to all filters and changeable parts and can act as weather protection while performing maintenance on the unit.

Six simple buttons provide operation of the QAX 24 with additional monitoring through an hourmeter, voltmeter and ammeter. Electrical connections are provided by 125 V GFCI duplex receptacles and 125 V/250 V power connectors.

The generator is also equipped with a transparent 21 gal. fuel tank that provides a runtime of 13 hours at full load, which Atlas Copco said eliminates the need for midtask refueling. Servicing has also been reduced for the QAX 24 unit to 500-hour intervals.

Dimensions for the QAX 24 generator are 124.4 in. long, 56.7 in. wide and 49.6 in. high. Weight is just under 2000 lb. and noise rating is 68 dB(A) at 23 ft.
