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.

What Types of Low-Pressure Blowers Do We Offer?
We offer a single-stage Z blower with asymmetric screw design (ZE/ZA), a high-speed direct drive turbo blower range (ZB), the first energy-efficient screw type air blower (ZS), and a range of multistage centrifugal blowers and exhausters (ZM).
