The ZH□B series (box type) was discontinued in August 2020.
The new ZH□B□A series is compact and lightweight, and the mounting variations have been expanded. For metric sizes, the mounting thread size and pitch are interchangeable.

For AC-A/AC-B/AC-D series modular F.R.L. units, the regulator is from the AR-A/AR-B/AR-D series.
For the part number of the round pressure gauge, refer to the AR-A/AR-B/AR-D series catalog. The modular F.R.L. unit catalog can be found here.
