Multistage Centrifugal Blowers and Exhaust Fans ZM | Atlas Copco China
Oil-free blowers and vacuum solutions up to 1.7 bar(g) / 25 psig
A flexible solution suitable for a wide range of low-pressure and vacuum applications.
The powerful ZM oil-free multistage centrifugal blowers and exhaust units deliver the air or gas, pressure, or vacuum you need, with very low maintenance costs.


Advantages of Multi-Stage Centrifugation Technology
Multistage centrifugal units are renowned for their reliable operation under harsh conditions and in high-risk environments. Consequently, they are widely employed in the oil, biogas, and mining industries. They are suitable for both pressurization applications involving air and gases (multistage blowers) and vacuum applications (multistage ejectors).
The advantage of a multi‑stage blower design lies in the ability to select the number of compression stages and the impeller configuration for each stage. This enables you to tailor the blower’s performance to your process requirements, achieving outstanding efficiency.


Biogas blower
Multistage blowers are commonly used in biogas production. They extract gas from sources such as sludge, enabling its purification and conversion into biogas. Gases like methane and carbon dioxide can cause corrosion, so the biogas production process requires robust equipment that is resistant to corrosion.


ZM Centrifugal Solutions
Whether you require air, gases, pressure, or vacuum, our ZM multistage centrifugal blowers and vacuum pumps deliver a range of performance levels to help you achieve the quality you need. These products can generate pressures up to 1.7 bar(g) / 25 psig and flow rates as high as 68,000 m³/hr / 42,500 cfm, making them ideal for numerous low-pressure and vacuum applications that demand high flow rates.
Reliable and safe operation
Our multi-stage blowers and vacuum solutions are designed to operate at temperatures exceeding 50°C / 120°F.
Stainless steel shafts and optional coatings protect the equipment from corrosive and dusty operating conditions, making it ideal for vacuum-based biogas removal and helping you minimize costly production downtime.
Our ZM multistage solutions all comply with ATEX and API 617 standards, ensuring safe operation in demanding environments.
Reduce energy costs
Each complete ZM multistage solution is equipped with a high-efficiency induction motor that drives the blower unit. These motors are suitable for both constant-speed and variable-speed operation and can operate at various voltage levels. Furthermore, their low-maintenance design ensures exceptionally minimal servicing requirements.
Customized according to your needs
Our ZM multistage solutions can be customized to meet your specific requirements. Whether you need a simple, turnkey blower for air‑handling applications or a sophisticated system for compressing flammable gases in hazardous‑area environments, we have the right solution for you.
You can also choose to use your own system to monitor and control the blower, or let us provide a sophisticated control panel that monitors the equipment’s operating status and adjusts the blower to your desired setpoint.
