Robust Blower

Robust

High pressure blower (side channel compressor). Despite small dimensions a true muscle man. Very compact design with enormous power. Thanks to the efficient sound insulation it is very quiet, can be installed in all orientations and is indestructible even under extreme conditions and in continuous operation.

Applications

The Robust blower is used to provide air flow to the family of Leister industrial heaters.  The proverbial performance and reliability of our products makes us the first choice

Featured Benefits

  • Better hot air processes - Because air volume and heating performance can be set independently, precisely and reproducibly from each other.
  • Up to 60% higher blower performance - Because the frequency converter lets the blower turn faster than the mains frequency
  • Lower system costs - Smaller and cheaper blowers can be used or fewer blowers will be necessary, because multiple air heaters can be connected to a blower.
  • Easy to integrate in the controller - By the remote control interface 4-20mA/0-10V or by fixed set values (up to 4) via clamp contacts.
  • Air supply controller - Active braking function enables quick air volume changes, i.e. for timed systems.
  • Save energy – heat only when necessary - There are timed processes, where hot air is necessary within a clearly defined time window. For the rest of the time, the air volume can be minimised and the heating performance switched off.
  • Simple plug & play installation - The frequency converter is already configured for operation with Leister blowers.
  • Secure - Integrated current monitoring and a built-in motor protection switch protect the blower.
  • Elimination of the motor condensator - This function is already integrated in the frequency converter.
