Automatic Selector By-Pass

Manufactured by Nardi Compressori, the Automatic Selector By-Pass (SKU PA011-049) is a vital accessory designed to streamline the cylinder filling process on a filling panel. Installed between the compressor, storage tanks, and filling panel, this device automatically manages airflow based on system pressure.

When a user opens the valves on the filling panel to begin drawing air from storage, the compressor starts automatically and supplies air directly to the panel. If the pressure between the storage and the filling panel equalizes, the By-Pass system redirects airflow, sending only freshly compressed air from the compressor to the panel.

Once the connected cylinders reach full pressure, the device continues running the compressor and automatically redirects airflow to the storage tanks, maintaining full system pressure without interruption. ATEX CERTIFIED ZONE II version available (SKU PA011-050).
