FAQ

What is the difference between a Roots blower and a rotary lobe blower?

There are no differences. These are just different terms used to refer to the same blower technology. The rotary lobe principle was invented by the Roots Brothers in Connersville, Indiana. It was patented in 1860 and named after them.

What are the advantages and disadvantages of rotary lobe vacuum pumps and blowers?

Rotary lobe vacuum pumps and blowers from Busch are robust, reliable, and cost-efficient. They have several benefits:

  • Low noise and vibration levels
  • Energy-efficient
  • Robust construction
  • Flow-optimized blower stages
  • Dry operating principle

Vacuum pumps and blowers with this technology are not suitable for chemical and pharmaceutical industries as they cannot handle chemicals or toxic gases.

Several factors have to be considered when selecting the right solution. These factors vary depending on the application and the specific needs of your process.
