Advantages

Advantages

 N/A
  • Maximum package efficiency - The combination of SIGMA Profile rotors, optimal motor-to-blower power transmission, and minimal pressure losses for all components ensures exceptional all-round efficiency.
  • Minimal pulsation in the connected process piping - Special silencers covering a wide frequency range significantly reduce machine and piping sound.
  • Reduced downtime - Highly durable components ensure reliable operation. The smart design eliminates the need for auxiliary devices (e.g. for sealing or cooling). Numerous sensors allow remote monitoring of operating status.
