The ACG series incorporates the gauge-in-handle regulator or filter-regulator into an air preparation combo. The integrated gauge creates a reduced profile and good visibility of the gauge even when mounted in low or high positions. Size 30 and 40 units now incorporate the transparent bowl guard, protecting them from the environment and providing 360 degrees visibility of the interior. The base color of the new ACG-B is white, maintaining a clean, modern look.
