Details & Features
The automatic selector unit enables simultaneous filling of breathing air cylinders via both a storage system and the compressor. Priority is given to the cylinders connected to the filling panel. Only once these are fully filled, the system begins replenishing the storage unit from the compressor. When the maximum storage pressure is reached, the compressor shuts off automatically. A new filling cycle begins as soon as another empty cylinder is connected.
The automatic selector unit performs three key functions:
- Pre-filling the breathing air cylinders from the storage system by pressure equalization.
- Filling the connected cylinder directly via the compressor until the final filling pressure is reached.
- Replenishing the storage system until its maximum pressure is reached.
Options
Pressure regulator
Instead of the standard pressure retention valve, a precise pressure regulator can be selected. It allows stable and exact adjustment of the overflow pressure – ideal for time-critical filling processes with storage systems. Temperature and environmental fluctuations have little effect on its regulation, making it the preferred option.
