Pneumatic clamping device with N2 filling unit - FT 11

The pressure hose is connected to the pressure reducer (accessory) of a nitrogen bottle. The nitrogen pressure is present up to the ball valve. The control manometer indicates the pressure. It also acts as a monitoring device during the filling process. The clamped sustained depression fire extinguisher is filled by opening a ball valve via spiral hose with quick coupling and via a filling connection (accessory). A tested pressure relief valveprotects the filling process.
