Low pressure compressed air is the backbone of many production processes. The ZB is the latest addition to Atlas Copco’s low pressure oil-free air solutions, manufactured to the highest standards of quality and reliability. Built to ensure complete product safety, ZB blowers guarantee a continuous, highly reliable, energy-efficient and 100% oil-free air supply for years on end.

Proven technology in a leading design

Wastewater Treatment Essential purity for wastewater treatment plants

Non-woven Textiles All-in-one blower technology for non-woven textiles

Flue Gas Desulphurization Cost efficiency & reliability for coal-fired power plants

Pneumatic Conveying High reliability & 100% oil-free air for industrial processing

Many wastewater treatment plants treat the wastewater using aerobic biological processes to digest waste by-products. Typically, the major energy users in such a treatment plant are the air blowers. With Atlas Copco low pressure ZB blowers, energy bills can be reduced thanks to the efficient impeller and bearing designs. To maximize productivity in these continuously operating plants, ZB blowers incorporate the latest technologies in the most efficient and reliable design. Thanks to a remarkably small footprint, flexible installation is ensured.

Either durable or disposable, non-woven materials serve in numerous applications such as diapers, surgical gowns and filters. During the creation of the fibers, compressed air is used. With the ZB, Atlas Copco offers an all-in-one ready-to-run package in an advanced yet compact design. Vibration and noise levels are significantly reduced, resulting in a more agreeable working environment for operators. In short, the ZB stands for long lasting performance, cost efficiency and easy installation, operation and servicing.

In coal-fired power plants, a continuous flow of low pressure air is used to remove sulphur dioxide from the exhaust flue gases. To guarantee uninterrupted pollution control and make sure these plants are up and running 24/7, the used compressed air solution needs to be highly reliable and energy-efficient. Atlas Copco’s low pressure ZB blowers fulfill this demand by offering a constant air flow at minimal energy costs.

In many industrial processes, dilute phase pneumatic conveying is used to transport goods. A reliable stream of low pressure oil-free compressed air – 100% certified according to ISO 8573-1 CLASS 0 (2001) – is essential to keep the production running smoothly. ZB blowers are designed as fully integrated and compact packages to ensure optimum efficiency and reliability. Combined with low noise and vibration levels this makes the ZB the perfect air solution for dilute phase pneumatic conveying.

Delivered ready for use, ZB blowers come as all-in-one packages including a powerful PLC controller, integrated VSD, forklift slots, check valve, air filter, blow-off valve and silencers. The compact design eliminates the need for extras and reduces installation to an absolute minimum, saving you time and money. Built for easy integration in your existing compressed air network, ZB blowers are up and running in no time.

Assuring your peace of mind

Through continuous investment in our competent, committed and efficient service organization, Atlas Copco ensures superior customer value by maximizing productivity. With a presence in over 160 countries, we offer professional and timely service through interaction and involvement. Uptime is guaranteed by dedicated technicians and 24/7 availability.

Driving down energy costs

Energy costs can amount to 80% of the Life Cycle Costs of a blower. Designed for reduced environmental impact, conforming to ISO 14001 standards, the ZB 5-120 VSD range helps to limit costs: the unique bearing design coupled with the turbo compression system provides the highest air volume at the lowest energy consumption. The integrated Variable Speed Drive (VSD) technology offers extra energy savings by automatically tuning the compressed air flow precisely to the air demand.

Unique benchmark technologyAlways at the forefront of innovation, Atlas Copco has been leading the industry in oil-free compressed air technology for many years. With the ZB Atlas Copco once again breaks new ground. At the heart of the new ZB range is a unique, state-of-the-art air bearing principle which, with a proven design, offers superior durability without the use of lubricants.

State-of-the-art air bearing principle:Zero oil involvedf

High efficiencyf

Friction-free floatingf

State-of-the-art air bearing principle:

Individually overlapping foils are f

assembled in the housing to support the motor shaft.

The shaft only comes in contact with the f

coated foils during starting & stopping.

As the shaft rotates, an air film is formed f

between the shaft and the foils which allows for friction-free rotation.

The air foil bearing principle meets high f

speed rotating requirements. When the speeds increase, pressure builds up and the load capacity enhances.

VSD: driving down energy costs

Energy consumption typically represents over 80% of a compressor's and blower’s Life Cycle Cost. Looking continuously to innovate and reduce customer costs, Atlas Copco pioneered the Variable Speed Drive technology (VSD) in 1994. VSD stands for major energy savings, while protecting the environment for future generations. Due to our ongoing investments in R&D, Atlas Copco offers the widest range of integrated VSD compressors and blowers on the market.

Varying air demand in 92% of all installationsIn almost every production environment, air demand fluctuates depending on different factors (time of the day, week or even month). Extensive measurements and studies of compressed air demand profiles show that 92% of all compressor and blower installations have substantial variations in air demand. Only 8% of all installations have a more stable air demand. Tests prove that even in this case, VSD compressors and blowers save energy.

Oil-free air is used in all kinds of industries where air quality is paramount for the end product and production process. These applications include food and beverage processing, pharmaceutical manufacturing and packaging, chemical and petrochemical processing, semiconductor and electronics manufacturing, the medical sector, automotive paint spraying, textile manufacturing and many more. In these critical environments, contamination by even the smallest quantities of oil can result in costly production downtime and product spoilage.

First in oil-free air technologyOver the past sixty years Atlas Copco has pioneered the development of oil-free air technology, resulting in a range of air compressors and blowers that provide 100% pure, clean air. Through continuous research and development, Atlas Copco achieved a new milestone, setting the standard for air purity as the first manufacturer to be awarded ISO 8573-1 CLASS 0 certification.

Eliminating any riskAs the industry leader committed to meeting the needs of the most demanding customers, Atlas Copco requested the renowned TÜV institute to type-test its range of oil-free compressors and blowers. Using the most rigorous testing methodologies available, all possible oil forms were measured across a range of temperatures and pressures. The TÜV found no traces of oil at all in the output air stream. Thus Atlas Copco is not only the first compressor and blower manufacturer to receive CLASS 0 certification, but also exceeds ISO 8573-1 CLASS 0 specifications.

CLASS 0 means:Zero risk of contamination.

Zero risk of damaged or unsafe products.

Zero risk of losses from operational downtime.

Zero risk of damaging your company’s hard-won professional reputation.

Current ISO 8573-1 (2001) classes (the five main classes and the associated maximum concentration in total oil content).
