  • Purely mechanical unit using dial gauges for pressure reading
  • High-end solution with integrated VSD inverter and Elektronikon® controller 

The blower’s positive displacement principle has been a reliable and cost effective solution for low pressure applications, including pneumatic transport, wastewater treatment and chemical applications in demanding environments. They can be installed wherever needed, whether it’s close to the technology or even outdoors.
