The automatic selector unit enables compressed air cylinders to be filled quickly and simultaneously in parallel from a single storage system (buffer) and via the compressor.
How it works:
The storage bottle connected to the filling panel takes priority for filling, i.e. the storage system and the compressor always start by filling the breathing air cylinders at the filling panel.
Once these cylinders have been filled completely, the storage system is topped up by the compressor.
When the maximum filling pressure is reached in the storage system, the compressor shuts down again entirely automatically. As soon as the next empty compressed air cylinder is connected to the filling panel, the fully automatic filling cycle starts again from the beginning.
