*1) Exit pressure range: P2 is 90% of P1 or less.
*2) different air consumption according to the tight pressure. Due to the construction, the pressure gap between the input and the output cannot be adjusted within 0.03MPA, even if the knob fits the maximum.

| AR4□5 | AR6□5 | AR8□5 | AR9□5 | |
| Medium | B24p | B25P | – | – |
| Pressure gauge with limit indicator | G46-10- □ 02 (max.1.0MPA), G46-2- □ 02 (max. 0.2MPA) | |||
*1) Indicate the type of connection thread in the piece of the pressure gauge (for example, G46-10-02). Do not put anything for RC and "N" for NPT thread.
Consult with VPC for NPT manometers.
*2) Be careful not to tighten excessively when it mount a pressure gauge, otherwise a breakdown could occur. Use a sealing tape for sealing.
