QAS 45

The Atlas Copco QAS 45 is equipped with an Isuzu 4LE engine and a Diesel Oxidation Catalyst (DOC) to achieve Tier 4 Final emission levels without the need for diesel exhaust fluid or a diesel particulate filter system.

Atlas Copco featured the QAS 45 portable generator Feb. 22-25 at booth 8935 during The Rental Showin New Orleans.
The QAS 45 generator is designed for predictable power and optimal operation with its reliable alternator, large fuel tank and simple control panel. The unit is equipped with a dependable Leroy Somer AREP alternator for superior starting capabilities. It also features a 72.5-gallon fuel tank for run times as long as 30-hours at 75-percent load. DeepSea 4510 controls are comfortable, reliable and easy to use. The backlit display shows all critical machine information, which can be viewed through a rugged Plexiglas® panel in the door. The generator has a remote start/stop controller and all functions are set with warning and showdown safety limits that can be easily customized by the user. 
The generator has high versatility with an optional voltage selector switch and 120vac GFCI duplex receptacles. Its optional voltage selector switch allows operators to adjust the machine’s output to 480 and 208/240 volt 3-phase settings as well as 120/240-volt single phase for varying applications and equipment. This versatility gives users greater flexibility on jobsites and can increase utilization at rental centers. Operators can lock the front panel on the voltage adjust potentiometer to prevent unintentional adjustments to the voltage, which can cause overheating or equipment damage. In addition, the QAS 45 features two 120vac GFCI duplex receptacles that are always powered, so contractors can operate small hand tools while running larger loads. And the QAS 45 ensures low decibel levels for use on noise-sensitive jobsites and residential areas with its sound-attenuated enclosure and a vertical radiator and exhaust discharge.
The QAS 45 has one of the highest resale values in the industry due to its overall durability as well as the quality and dependability of its interior components. For example, the QAS 45 is mounted on a durable frame and surrounded by a robust enclosure formed from galvanneal steel and powder coated for a long-lasting, scratch- and corrosion-resistant surface.
Large doors and having all maintenance points on one side of the generator ensures that servicing downtime is kept at a minimum. The DOC after-treatment device requires no regeneration or maintenance. The engine meets Tier 4 Final emission standards without the need for diesel exhaust fluid or a diesel particulate filter system. Further, engine fluids are plumbed to the edge of the skid to eliminate the hassle of maneuvering pans into the interior space. The spillage free base-frame is sized for 110 percent containment of all the machines fluids and fuel, giving users confidence in the most environmentally sensitive areas. And, the extended life filters have 500-hour service intervals resulting in reduced maintenance costs.
The QAS 45 comes equipped on a trailer with robust tie-downs for safe transport on a flatbed. The unit also can be skid mounted and include fork pockets for moving it with a forklift. All units come with a standard single-point lifting eye in the enclosure for maneuvering with a crane.
