Aerzen Positive Displacement Blowers for oil-free air and gas conveying.

Aerzen Positive Displacement Blowers (of the "Roots" type design) have been manufactured since 1868 and today are highly developed standard production machines designed and adapted for a broad range of applications. The following are some examples Aerzen Positive Displacement Blowers applications:

Pneumatic conveying of bulk materials

In suction- or discharge pressure. Machine sizes range from small blowers installed in tank vehicles to very large ones used in pneumatic elevators for vacuum operated ship unloaders. The hourly capacity of such unloading installations is up to 1000 tons at present.

Pressurized aeration of basins in sewage treatment plants
Filter flushing blowers in drinking water production plants
Gas boosting blowers rated for internal static pressures of up to 25 bar.
Steel production -
Application in direct-reduction plants.
High vacuum boosters - are equipped with special shaft seals.
Conveying of pratical all gases - found in the chemical, petrochemical, and metallurgical industries. Special designs are available to handle aggressive gases. Machines used in both conventional and nuclear power plants comply with the various categories of safety regulations.
