Vacuum Blowers

The blades (A) transport, accelerate and compress the air on the momentum principle. The air is dragged by the blades in this case. A vacuum is created at the suction end (B) this way. The compressed air (exhaust air) escapes through the outlet opening (C).

Blowers provide a very high suction rate due to the large air channel volume and specially shaped blades.

Advantages of vacuum blowers

• Enormous suction rate
• High leakage compensation
• Evacuation of large volumes in a short time

Typical areas of application

• Handling of porous workpieces, such as cardboard,
  insulation material, chipboards or bags

We distinguish between two basic types of vacuum blowers:

• Vacuum blowers are either directly driven or frequency-regulated.
• Used especially for handling porous workpieces (chipboards, bags, etc.).
• Frequency-controlled blowers can be customized by controlling the motor speed and respectively the suction rate.

• Vacuum blower with electro-pneumatic reversing for control of suction, blowing and neutral position.
• Used for handling air-tight workpieces that are picked up and deposited quickly.
