- Model 5 - Blower Units Generation


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.

Blowers are Blowers, Right? an End to Preconceptions

Extremely Robust

  • For a broad range of applications in control ranges from 25 to 100%
  • Many types of possible modifications

Compact Design

  • Space-saving side-by-side setup
  • Smaller engine rooms

Operation-Friendly, Low-Maintenance Design

  • Control and maintenance from the front of the machine
  • Oil levels can be checked with the machine running and are readable from outside the machine
  • Plug&play (Pre-configured, parameterized, ready to run)

No Absorption Material

  • For use in the pneumatic conveyance of bulk food items (no contamination).
  • Secure, energy-efficient water treatment (no deposits of absorption material on aeration plates, no clogging of filter media, no pressure losses)

A Plus for the Environment

  • Energy-efficient Class IE3 motors as standard equipment
  • Newly developed E-Design for even more energy efficiency

Low Noise Levels
