Aerzen Positive Displacement Blowers for the oil-free conveying and compression of air and gases

Aerzen Positive Displacement Blowers (of the „Roots Blower“ type design) have been manufactured since 1868 and today are highly developed standard production machines designed and adapted to fnd use in a wide variety of applications.
The following are only a few examples of the many applications in which Aerzen Blowers can be used:

• Roots Blower 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 un loaders. The hourly capacity of such unloading installations is up to 1000 tons at present.
• Pressurized aeration of basins in sewage treatment
plants
• Filter fushing blowers in drinking water pro - duction
plants.
• High vacuum boosters are equipped with special shaft
seals.
• Conveying of practically 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.
• Gas boosting blowers rated for internal static pressures of up to 25 bar.
• Steel production Application in direct-reduction plants.
Oil-free conveying The fact that Aerzen positive displacement blowers convey the medium oil-free is a decisive advantage in pneumatic conveying, in water fltration plants, and in the food and chemical industries. Since the rotary pistons revolve without making contact with each other and the housing, no lubrication is required in the conveying chamber, which guarantees that the medium conveyed remains free of contamination from lubricants and wear particles.
Conveying based on the positive displacement principle The inlet fow volume varies only slightly in response to changes in back pressure. Blower output can be adapted in the swept volume to the operating conditions simply by varying its speed.

Wide range of selection The extensive number of models and sizes available facilitates the selection of the optimal machine
for any given application. Machines handling capacities ranging from approx. 30 m³/h to approx. 84000 m³/h in either vertical or horizontal for configuration can be supplied.
Drive types Blowers are driven by electrical motors, internal combustion engines, hydraulic or compressed air motors
via flexible coupling (arrangement 4, DA), fanged motor B 5 (for HV - blowers). V-belt drive (arrangement 5, FA) Reducer drive, shift gear transmission or variable speed drive (arrangement 6, 6 h) High mechanical efficiency Since the rotary pistons revolve without making contact, mechanical power losses are generated in the bearing and timing gear assemblies only. The use of ball and roller bearings as well as tempered and ground timing gears reduces these losses to an absolute minimum. Furthermore it is advantageous that the helical gearing offers a running of low noise. High volumetric effciency The rotary pistons and casing components are manufactured using modern CNC-controlled precision machine tools, guaranteeing exact tolerances even in the large scale production of standard components. This is refected in the minute clearances both be - tween the rotors as well as between the rotors and the housing, resulting in very high degrees of volumetric effciency.
Operating reliability and safety Aerzen positive displacement blowers are produced by highly skilled and experienced professionals, and are not delivered prior to having been thoroughly tested.
Each and every blower is subjected to a test run lasting several hours under conditions of increased load. A test record is prepared with all data which will still be available years later.
