Low-Pressure Technologies in Focus
The Screw Blower in Focus
Just as the rotary screw compressor is one of the backbones of the industrial world, so has the rotary screw blower evolved into one of the mainstays of the low-pressure world.
The Centrifugal (Turbo) Blower in Focus
Centrifugal blowers are type of blower that operates via dynamic compression and are well-suited for processes in a variety of industries, including wastewater treatment and pneumatic conveying.
The Lobe Blower in Focus
Lobe blowers, also referred to as rotary lobe blowers or Roots blowers, are a type of positive displacement blower originally invented in the 1800s by the Roots brothers - and they're still popular today!
Considerations for Selecting a Blower
A thorough analysis of your installation and application is key to selecting the right technology, and there will undoubtedly be one or more aspects might take precedence over others.
