All important functions such as - pressure regulator 2-stage, automatic switching, safety blow-off device are integrated into just one part, making installation easier and more error-free installation. 3. This switching system guarantees that 2 bottles can never be empty, because during the automatic switching process, the reserve bottle is always converted into an operating bottle, so that only one bottle remains in operation until it is completely emptied. Further advantages: The "switching arrow" (green = operation, red = reserve or empty) indicates which bottle is in operation or empty. * The automatic bottle switching takes place without interruption of operation, this is guaranteed even when changing bottles. * The integrated safety blow-off valve prevents impermissibly high pressure that could damage the equipment. * The plastic switch swivel cap also prevents moisture from entering the regulator area. * 2 HD hoses allow universal connection to 3, 5 and 11 kg bottles. * Also available for the 50 mbar range, DVGW tested. The propane gas bottles are of course not included.
