Low-Pressure Blowers

Explore our range of low-pressure blower technologies, suitable for a wide range of applications.

Atlas Copco: Innovator of Low-Pressure Blower Technologies

What Are Low-Pressure Blowers? Blowers and low-pressure compressors are specifically engineered for applications that require a pressure between 0.3 and 4 bar(g). Enormous energy gains can be made by choosing the right type and size of compressor for your applications. That's why Atlas Copco introduced several low-pressure technologies into the market, each of them engineered to match the exact pressure and flow requirements of your application.

Common Applications Using Blowers Blowers are used in a wide variety of applications and processes. Wastewater treatment, cement manufacturing, food and beverage, mining, bulk handling, and pneumatic conveying are common examples of these.

ZL 3 VSD exterior 360° view
ZL Rotary Lobe High Performance and Low Costs Thanks to the simplicity and the tested design of the lobe blower, it is the ideal choice for difficult environments around the world that have limited supervision requirements, providing the exact amount of air requested by the application.
Methods of Operation • Pressurized (up to 14.5 psig) • In a vacuum (up to -7.25 psig)
ZS 4, ZS
ZS Oil-Free Screw Blower
A Complete Package for All Applications The ZS blower is designed to guarantee maximum product safety. It ensures a continuous and long-term supply of oil-free air, it is highly reliable and energy-efficient in all your applications, and has the lowest possible operating costs.
Maintenance costs and downtime are reduced due to the innovative technology of the screw blower. The blower is also available in a Plug & Play version, with an on-board ready-to-use Y/D starter or inverter.
turbo blower
ZB VSD Centrifugal Blower Proven Reliability Low pressure compressed air is the basis of many production processes. A reliable and constant flow is essential and the air quality must be high. Aeration for waste water, printing, air separation, fermentation and processing of non-woven fabric do not tolerate product contamination.

The Atlas Copco ZB range is the ideal choice for meeting the high demands of these processes. This range offers a complete package that comes with all the components perfectly synchronized.

ZE/ZA Single Stage Screw Compressor Easy Installation
The ZE/ZA compressor is supplied as a ready to use all-in-one package and includes a powerful controller and an optional integrated after-chiller (internal or external depending on the model). The completeness of the supply eliminates the need for additional components and minimizes installation work, consequently saving time and money.
The ZE/ZA compressor is immediately operational, as it is built to be easily integrated into the existing compressed air network.
ZM246 multistage centrifugal blower and exhauster
ZM Centrifugal Blower with Side Channels
Great Energy Efficiency in the Compression of Air or Gas, Including in a Vacuum The ZM series is a centrifugal blower with oil-free compression and a variable number of stages, depending on the desired flow rate and pressure.

The blower is air cooled and is designed to be used with an inverter and based on a pressure range of up to 20 psig (under pressure), -7.25 psig (in a vacuum) and a flow rate up to 32,000 psig for air or gas.
