Blower units DELTA BLOWER Generation 5

Positive Displacement Blowers

Rotary lobe blowers for air and neutral gases

The Delta Blowers. Robust, durable machines for countless compressor processes.

The Delta Blower Generation 5 is the synthesis of the successful characteristics developed in previous generations combined with new technical innovations that already meet the market requirements of the future. Aerzener Maschinenfabrik was the first blower manufacturer to design compact units in 1960 and has developed this machine type continuously ever since. Delta Blower Generation 5 is therefore already the 5th generation of AERZEN blower units and represents the successful combination of tradition and innovation. 

Special advantages speak for the use of Aerzen DELTA BLOWER Generation 5

    • Low noise levels due to considerable sound reductions
    • Operation-friendly & low maintenance design
    • Mechanical fan
    • No absorption material
