The AirTAC GR40015JC1TK AirTAC Air Pressure Regulator NPT 1/2 in 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 GR40015JC1TK is an AirTAC GR400 series air pressure regulator for compressed air, built for pressure regulation only - no filter, no bowl and no lubricator. This size 400 unit has 1/2 in NPT ports, a standard regulation range of 0.05-0.9 MPa (7-130 psi) and a maximum inlet pressure of 1.0 MPa (145 psi). The code confirms a round external gauge with an MPa scale and a reverse (check) valve fitted, and no mounting bracket is included, though the GR body is also panel-mountable. It operates from -20 to 70 C, a wider temperature window than the rest of the G family.
This is a genuine AirTAC part. The GR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and in PT, G (BSPP) or NPT thread, with gauge and scale options, a low-pressure type and a reverse-valve option to choose from. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 stable downstream pressure for a clamping or press cylinder circuit on a machine tool, with the check valve holding the setting if the upstream supply drops.
Feed a regulated air drop to a CNC machining centre's pneumatic actuators and tool-change circuit, with the MPa round gauge giving a clear local setpoint readout.
Regulate the supply header feeding sealers and pick-and-place actuators on a packaging line, using the 1/2 in NPT connection to match the plant's NPT air piping.
Pick the GR size by the port and flow step you need: 200, 300, 400 or 600, with ports from 1/8 to 1 in - larger sizes carry more flow. This unit is the standard (not low-pressure) type with a 0.05-0.9 MPa (7-130 psi) setting range; the L-code low-pressure type tops out at 0.4 MPa if your line runs lower. Choose the gauge scale (MPa, psi or bar) and round vs embedded square gauge to suit the operator, and specify PT, G (BSPP) or NPT thread to match your piping - PT is the catalogue standard, G and NPT are order options. The K-code reverse/check valve on this unit holds the downstream setting if upstream pressure is lost. One honest note before ordering: regulator flow is published as curves, not a single rated number, so send us your application conditions and we will confirm sizing against the datasheet before you commit.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. 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 flow number. Send us your inlet pressure, set pressure and required flow, and we will confirm the sizing against the datasheet on request before you order.
In GR40015JC1TK, the C means an external round gauge is fitted and the 1 sets its scale to MPa (psi and bar scales are also available). The K at the end means a reverse/check valve is fitted, which holds the downstream setting if upstream pressure is lost. The unit has no bracket included but is panel-mountable, and the NPT thread is an order option alongside the PT standard.
