3 Product sheet, Specialty gas REDLINE® Gas panels A 208. Semi-automatic gas panel. Single stage, semi-automatic gas supply panel with internal gas purging, designed for high purity gases and mixtures. Gas panel A 208 is a semi-automatic gas panel designed for uninterrupted gas supply. Switch-over between the two connected cylinders or bundles occurs when the pressure of one side (the primary side) falls below a preset pressure level. This is achieved by two integrated regulators (factory-set to slightly different delivery pressure levels) which are connected at their outlet ports. Semi-automatic supply panels should be connected to an alarm so that the cylinders will be switched on time. The panel can also be equipped with contact gauge (/C models) for automatic surveillance. When applicable the panel can be ordered with residual gas line (/R models) connecting the relief valve with the purge outlet. Continuous supply of pure gases Automatic switch over without auxiliary power Positive indication of active cylinder Process-gas purging system High ow capacity Compact design ® HiQ and REDLINE are registered trademarks of The Linde Group.
