GR200, GR300 and GR400 air regulators combine a recessed square gauge with a locking pressure-adjustment mechanism. Their balanced regulating design supports manual pressure control, while seven PT port configurations provide a choice of connection size and flow capacity.
| Model | Port P | Maximum flow, L/min (ANR) |
|---|---|---|
| GR200-06 | PT1/8 | 3000 |
| GR200-08 | PT1/4 | 3000 |
| GR300-08 | PT1/4 | 4500 |
| GR300-10 | PT3/8 | 4500 |
| GR300-15 | PT1/2 | 4500 |
| GR400-10 | PT3/8 | 6500 |
| GR400-15 | PT1/2 | 6500 |
For GR300-10, G identifies the series, R the regulator function, 300 the body size and 10 the 3/8″ connection. Other port codes are 06 for 1/8″, 08 for 1/4″ and 15 for 1/2″.
