Since the product introduction of the extremely efficient turbo blower series, Aerzen Turbo, numerous AERZEN customers worldwide have already benefited from the energy savings. The AERZEN development team has now turned the efficiency screw once more for the sizes AT400-0.8T and AT400-1.0T.

Sizes AT400-0.8T and AT400-1.0T
The improved energy efficiency is the result of a redesign of the so-called twin turbo stages, in which two impellers run in parallel on the motor shaft of the permanent magnet motor. On the basis of complex CFD (Computational Fluid Dynamics) analyses, the turbo stages were driven to new peak values in terms of energy efficiency and motor cooling and were granted a corresponding patent.
Numerous advantages
The Aerzen Turbo sizes AT400-0.8T and AT400-1.0T cover flow rate ranges up to 16,000 m³/h, differential pressures up to 1 bar and drive capacities up to 300 kW.
The innovative Aerzen turbo series are characterised by the following advantages:
- Increase in energy efficiency of up to 15% compared with conventional turbo technology
- Extended bearing life thanks to innovative AERZEN air bearings with double coating (>80,000 operating hours, independent of start and stop cycles)
- Highest reliability even under extreme operating conditions and pressure fluctuations
- Lowest maintenance effort, only regular filter change
- 100 percent oil-free
- Extended application possibilities at ambient temperatures up to 50°C
- Active pump protection through automatic speed increase
- Space-saving design
