Overview
The Norgren B74G-6AK-AD1-RMG is a 3/4″ PTF (NPT) Excelon series filter/regulator that combines accurate pressure adjustment with bulk water (moisture) and particle removal in one unit, saving space and pneumatic connections for the same or improved performance. This configuration features a 5 µm filter element, automatic drain, aluminum metal bowl with liquid level indicator, relieving diaphragm, push-to-lock knob adjustment, and an integral pressure gauge calibrated in bar and PSI.
