+Ordering notes

As an option:
  • Blow-off function / aeration of vacuum line with vacuum pressure reversing valve: Switch from vacuum to pressure generation by reversing the flow direction without need to change the rotation direction
  • Vacuum safety valve when operation with closed suction inlet cannot be prevented. Alternatively a 3/2 way valve can be used.
  • Vacuum safety valve to prevent overheating as side channel blowers are generally not suitable for continuous operation at max. vacuum level
