The AirTAC GR40015JC2T AirTAC Air Pressure Regulator NPT1/2 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT1/2" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR40015JC2T is an AirTAC GR-series air pressure regulator, a genuine AirTAC part dedicated to one job: holding a stable, adjustable downstream pressure from a compressed-air supply. This size 400 unit has a 1/2 in NPT port (NPT is the trailing T in the code; PT is the standard thread and G/NPT are order options), the standard regulator type, and a maximum inlet pressure of 1.0 MPa (145 psi). Its regulation range is 0.05-0.9 MPa (7-130 psi), and it carries a round external gauge with a psi scale, as selected by the C2 code. The J code means no mounting bracket is fitted; GR regulators are also panel-mountable. As a GR unit it contains no filter and no bowl, and its operating temperature range is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC component from the GR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, gauge scale choices, a low-pressure type option, and an optional reverse/check valve. We confirm flow and other datasheet figures on request, since flow is published as curves rather than a single rating.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Set a steady holding pressure for clamp cylinders on a fixture line, so clamping force stays consistent from part to part regardless of supply swings.
Feed bagger or cartoner actuators from a regulated drop so sealing arms and pushers run at the pressure the machine was set up for.
Regulate the supply to gripper valves on a robot cell so part grip is repeatable, with the psi gauge giving operators a clear local setpoint readout.
Choose the GR size by the port and flow step your line needs: this unit is size 400 with a 1/2 in NPT port, one step up from 3/8 in and one below 3/4 in. Set the outlet pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your circuit runs low, the L low-pressure type (up to 0.4 MPa) is the alternative. Gauge options are the embedded square gauge or an external round gauge, in MPa, psi or bar scales - this configuration has a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT orderable; this code selects NPT. You can also specify a bracket (omitted here, J) and a reverse/check valve (K, not fitted here).
Flow for GR regulators is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your port size, inlet pressure and target outlet pressure, and we will confirm the flow from the datasheet on request before you order.
The C2 in the code selects the optional external round gauge with a psi scale; the standard configuration is the embedded square gauge. Gauges are available in MPa, psi or bar scales, so you can order the version that matches the instruments already on your plant.
