Leister now offers a frequency converter FC-550 as an accessory for the ROBUST, SILENCE and ASO blowers. With it you can steplessly adjust the air volume – with a push of the button or remote controlled by a PLC (Programmable Logic Controller). The blower performance can be increased by up to 60%. The results are more efficient processes and therefore lower costs.
The FC-550 can simply be connected between the current supply and the blower.

Benefit of frequency converter with Leister blowers
1. Better hot air processes
Because air volume and heating performance can be set independently, precisely and reproducibly from each other.
2. Up to 60% higher blower performance
Because the frequency converter lets the blower turn faster than the mains frequency.
3. 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.
4. 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.
5. Air supply controller
Active braking function enables quick air volume changes, i.e. for timed systems.
6. 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 minimized and the heating performance switched off.
7. Simple plug & play installation
The frequency converter is already configured for operation with Leister blowers.
8. Secure
Integrated current monitoring and a built-in motor protection switch protect the blowers.
