The automatic selector unit – for simultaneous filling of compressed air cylinders from storage system and compressor
The automatic selector unit enables compressed air cylinders (cylinders) to be filled quickly at the filling panel from a single storage system (buffer) and via the compressor simultaneously. It also supports the subsequent automatic refilling of the storage system by the compressor.
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 the storage bottle has been filled, the automatic selector unit ensures that the storage system is then filled by the compressor.
When the maximum filling pressure is reached in the storage system, the compressor shuts down again. As soon as the next empty storage bottle is connected to the filling panel, the automatic cycle starts again from the beginning.
