3 Economy + Efficiency = ZS + RELIABILITY & AVAILABILITY For over sixty years, Atlas Copco has been leading the industry in oil-free compressed air technology, drawing on vast experience and continuous technological innovations. Rest assured: severe certification and testing procedures are conducted to ensure the air supplied meets the highest standards of quality control. With the protection of your application in mind, Atlas Copco has designed its ZS + range to offer you superb oil-free quality air. LOW NOISE Employees working close to a ZS + blower will notice the difference. Its fully silenced package plus a reduced pulsation level in the piping mean that noise and vibrations are noticeably reduced. The result is a minimized impact on the surrounding environment, improved employee comfort and better concentration on the job at hand. INTEGRATION Efficient oil-free air + Reduced energy cost Low pressure air is a prerequisite for the continuity and quality of many manufacturing processes. To keep your production and processes running smoothly, a constant delivery of air is essential. In short, overall production reliability is your key concern. Opt for Atlas Copco s advanced ZS + blower range and you obtain the ideal solution to meet the high demands your process imposes on your blower. The ZS + series offers the pure oil-free air you need while providing improved energy efficiency. With energy amounting to over 70% of a blower s lifecycle costs (LCC), its importance is clear. The most cost-effective compressed air solution optimizes the pressure, volume and air treatment equipment for each production process. Atlas Copco s ZS + blowers provide you with the ultimate, all-in-one, fully integrated package to reduce your electricity bill by 40%. The use of gear driven screw elements assures less mechanical losses compared to regular, belt driven roots blowers. The ZS + comes as a complete, fully integrated package, including Variable Speed Drive, controls, canopy, silencer and valves. There are no hidden costs. It arrives ready for easy, plug-and-run installation, saving you time and money, and its reliable performance is backed by Atlas Copco s global sales and service organisation at all times. Class 0 You can t afford to compromise on clean, oil-free air for your critical processes. Atlas Copco, a pioneer in oil-free air screw technology, is known for its range of compressors designed especially for applications that require oil-free air. We are also the world s first compressor manufacturer to receive certification for a new industry standard of air purity: ISO CLASS 0.

6 Proven technology Set to fulfill and even exceed your expectations and demands, Atlas Copco s ZS + series is the result of decades of experience in oil-free design and manufacturing. Uniting a range of advanced technologies, the ZS + blower offers you Atlas Copco s proven knowledge in a class leading design. 100% oil-free air Designed and manufactured by Atlas Copco Proven, oil-free screw compression Fully synchronized rotor assembly Efficient shaft sealing No residual oil in the air Superior rotor coating ROTORS The compression principle is simple Compression is internal, allowing for increased efficiency. Two helicoidal rotors, one with four lobes and the other with six flutes, turn into each other. The former screw turns 50% faster than the latter. The intake air is compressed between the rotors and their housing. GEARS The intermeshing compression rotors never touch, thanks to precision timing gears that maintain minute clearances between the rotor surfaces. Wear and tear is eliminated and no lubrication is required in the compression space. SEALS Special seals prevent air escaping along the rotor shaft, while separate seals stop oil escaping from the rotor bearings into the compression chamber. The result is 100% oil-free and pulsation-free air. MOTOR AND COMPRESSOR PERMANENTLY ALIGNED Unlike belt-driven compressors, ZS + blowers incorporate a flanged motor housing and gearbox element, offering permanent alignment during transport, installation and operation of the unit. Highly efficient, totally enclosed fan-cooled electric motor (IP55, Class F).

Full sound enclosures substantially reduce noise levels, while rotary screw technology minimizes vibration. ADVANCED CONTROL AND MONITORING You rely on your compressed air solution to perform efficiently day in, day out. To guarantee maximum uptime, continuous surveillance is a must. The Elektronikon operating system provides control and monitoring to increase your blower s efficiency and reliability. Easily expandable with extra sensors, digital inputs and internet communication functions, the Elektronikon can be adapted to your specific needs and offer simple, central control of up to four compressors. True performance Atlas Copco s ZS + blowers are measured according to ISO 1217 Ed. 3, stipulating the FAD measurement at the outlet of the package, net of all losses. Atlas Copco specifications correspond to the capacity and pressure the customer receives, not to the intake volume of the blower. Differences are substantial. intake volume Intake volume - l/s - m 3 - cfm delivered volume FAD - l/s - m 3 /min - cfm External leakages External leakages Net usable air Inlet flow referred to blower element inlet conditions. Seal leakages and inlet losses should not deprive you of the air you paid for. FAD according to ISO 1217 Ed. 3. A ZS + blower truly delivers what is promised.

8 Reduced costs Considering that the generation of compressed air can account for more than 40% of a plant s total electricity bill, optimizing energy usage is crucial. In Atlas Copco s VSD (Variable Speed Drive) technology, we provide you with a partner on the road to unrivalled cost savings. The integrated frequency converter of the ZS + VSD series varies the speed of the drive motor to match the changes in your compressed air demand, thus using a minimum amount of energy and more than justifying the additional investment. SUPREME ENERGY SAVINGS Precise pressure control for optimal efficiency. Shutdown scheduling to avoid costs during non-working hours. Prioritized use of the most economic machines over older, less effective versions. Continuous usage of VSD machines. Use of multiple VSD blowers in their most efficient performance zones. LOWEST POSSIBLE RUNNING COST Air supply = air demand. With a varying air demand pattern, motor speed regulation is the most efficient blower control method. Energy savings at partial load. CONSTANT PRESSURE & LOW STARTING CURRENTS Process stability improvement. Reduced investments in electrical systems. No peak current penalties. Smooth starting. NO SPEED WINDOWS The blower can be regulated steplessly within the speed range.
