ZB 5-120 VSD 5-120 kW/7-160 hp
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.
Wastewater Treatment
Flue Gas Desulphurization
Essential purity for wastewater treatment plants
Cost efficiency & reliability for coal-fired power plants
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.
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.
Non-woven Textiles
Pneumatic Conveying
All-in-one blower technology for non-woven textiles
High reliability & 100% oil-free air for industrial processing
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 many industrial processes, dilute phase pneumatic conveying
is used to transport goods. A reliable stream of low pressure oilfree 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.
Keeping your production up and running
A reliable supply of compressed air is critical to ensure production continuity. Every ZB is designed, manufactured and tested in accordance
with ISO 9001 stipulations. The advanced design incorporating air foil bearings, low vibration turbo technology and integrated VSD contributes
to the ZB’s exceptional reliability. Built in line with long standing internal engineering practices, the ZB is easy to maintain which reduces
operational costs. With low vibration and noise levels, Atlas Copco also focuses on the operator’s needs.
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.
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.
Protecting your reputation and production
Easy installation
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.
ZB 5-120 VSD 5-120 kW/7-160 hp
In virtually any application, oil contamination of the air supply causes serious productivity issues and increases costs. As the first manufacturer
to receive ISO 8573-1 CLASS 0 (2001) certification for its oil-free air blowers, Atlas Copco has set a new standard in air purity. Focusing on
the protection of critical applications as well as today’s increasing quality demands, Atlas Copco offers TÜV-certified 100% oil-free air.

Unique benchmark technology
Always 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.

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 installations
In 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.

adjusting the motor speed. This results in large energy savings of up to 35%.
The Life Cycle Cost of a compressor and blower can be cut by an average of 22%.
In addition, lowered system pressure with VSD minimizes energy use across
your production dramatically.

CLASS 0: the industry standard
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 technology
Eliminating any risk
Over 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.
As 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.
