The AirTAC GR30015JC1T 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 GR30015JC1T is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream compressed-air pressure steady at the value you set. This configuration is the 300 size with 1/2 in NPT ports, the standard regulator type with a setting range of 0.05-0.9 MPa (7-130 psi), and a round pressure gauge fitted on the MPa scale so the setpoint can be read and adjusted directly. It carries no bracket, and as a GR unit it is also panel-mountable. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include a low-pressure type (up to 0.4 MPa), a reverse/check valve, embedded square or external round gauges on MPa, psi or bar scales, a mounting bracket, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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.

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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 and hold a stable working pressure feeding the air cylinder on a bench or frame press, so the forming or staking stroke repeats at the same setpoint shift after shift.
Regulate the air feeding sealing bars, diverters and clamp actuators on a packaging or cartoning line, keeping downstream pressure steady as other machines on the same header draw air.
Provide a fixed, adjustable supply pressure to gripper and end-of-arm-tooling valves on a robotic cell, protecting delicate parts from over-pressure at the gripper jaws.
Start with the port and size step: this unit is size 300 with 1/2 in NPT ports, and the GR family steps through 200/300/400/600 with ports from 1/8 in to 1 in, so pick the step that matches your line size and required flow. Set the gauge scale you want to read (MPa, psi or bar) and choose the embedded square or external round gauge style. Choose the thread to order: PT is the standard, with G (BSPP) and NPT as catalogue options, exactly as coded here with the T suffix. Decide on the mounting bracket (this code omits it; the GR is also panel-mountable) and, if your circuit needs one, the reverse/check valve option. If your working pressure never exceeds 0.4 MPa, the low-pressure L type is the matching variant. One honest note on sizing: GR flow is published as curves, not a single rated number, so send us your application details and we will confirm the 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 GR regulator flow as curves, not as a single rated figure, so we do not quote a rated flow number for this unit. Send us your line size, inlet pressure and downstream demand, and we will confirm the relevant datasheet curve figures for your application on request before you order.
In GR30015JC1T, J means no mounting bracket is fitted (the GR is also panel-mountable), C means an external round gauge is included, and 1 means the gauge reads in MPa. Gauge scale (MPa, psi or bar), gauge style, bracket and thread (PT standard, G or NPT) are all decodable order options - pick the combination that matches how you want to mount and read the unit.
