A built-in pressure gauge, mountable at any angle, depending on the piping direction ensures good visibility of the pressure gauge, even when the AWG is mounted at an overhead or underfoot location. Equipped with a special mechanism, the pressure gauge will not be revolved even after the handle is operated. Due to the unique design, substantial space reduction is achieved when the AWG is panel mounted. "Note that the AWG-B has been released as a replacement for the AWG. While the AWG is still supported with inventory and no obsolescence date has been announced, we strongly encourage the use of the AWG-B for new applications"
