Positive Displacement Blowers

Modular system for large blowers for process air applications

Alpha Blower

1. Horizontal or vertical conveying direction

2. Volume flow gradation via modular system

3. 2-lobe and 3-lobe rotor design available


The key to the most efficient large blowers made by AERZEN is: It is always the right size. This means that AERZEN provides you with the right blower size for each individual application. Thanks to the Alpha Blower as new modular system, for the first time, you have the choice between 26 different types. Perfect for a safe and highly efficient operation of your process air applications.


The Alpha Blower represents robustness, combined with maximum precision and ultimate safety. This blower has been optimised in terms of flow design and processes. The well-known features have been further improved without neglecting the proven system. Finely graded sizes support the efficiency increase as well as innovative component developments. Above all, the low energy consumption is decisive. Each AERZEN blower is specifically tailored to your process and configured accordingly: Therefore, it is always the right size.

Alpha Blower - as individual as never before. Besides the variations of sizes numerous modifications and a wide spectrum of accessories round off the AERZEN modular system. Thus, AERZEN guarantees you maximum customisation. These options make the Alpha Blower a real solution provider - for each customer requirement.

The Alpha Blower is available in 2-lobe or 3-lobe design.

Advantages 2-lobe blower technology

  • High efficiency in negative pressure operation
  • Low investment costs
  • Pulsation reduction due to soft inlet as well as multi-flow principle and optional AirSilence

Advantages 3-lobe blower technology

  • Low pulsation in the piping
  • Reduction of shocks
  • High efficiency in overpressure operation
  • Optimised sound absorption due to smaller silencer 

Alpha Blower - Perfect for a safe and highly efficient operation of your process air applications.

Wherever quality, reliability and machine safety are required, e.g. in case of critical processes or difficult ambient conditions, AERZEN offers a solution tailored to each individual application.

For example pneumatic conveying: In many cases, the transport of bulk material is carried out by pneumatic conveying.AERZEN largest machines are installed, e.g in lifting systems. They unload transport vessels with an hourly performance of up to 1,000 tons.

For example for the production of oxygen: AERZEN positive pressure blower takes care of the air supply in the tanks of the molecular filters. The evacuation is done by means of the proven AERZEN vacuum blowers. To increase productivity and to decrease  operational costs, the application of the AERZEN Alpha Blower is the right choice. This type of blower offers robust and long-lasting operation, which stands for an economical compressed air production with high volume flows.
