The AirTAC GR40015JC1T 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 GR40015JC1T is an AirTAC GR400 air pressure regulator for compressed air. It reduces and holds a stable downstream pressure anywhere in its 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration has 1/2 in NPT ports, the standard regulator type, a round pressure gauge scaled in MPa, and no mounting bracket; GR units are also panel-mountable. The GR series works from -20 to 70 C, a wider temperature window than the rest of the G family.
This is a genuine AirTAC part. The GR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include G (BSPP) or NPT threads, psi or bar gauge scales, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and bracket variants. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application.

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.

| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| (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. |
| (blank) | No reverse-flow valve (the default). |
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 the supply pressure to pneumatic clamps and fixtures on a machining centre so workpiece holding force stays consistent across every cycle.
Regulate the air feeding cylinders on a packaging machine - carton closers, pushers and label presses - so stroke speed and gentle handling stay repeatable.
Trim the atomizing pressure delivered to spray guns in a paint finishing booth, giving the operator a stable, dialled-in setting at the gun.
Choose the size by the port and flow step: 200 through 600, with ports from 1/8 to 1 in - this 400 unit carries 1/2 in NPT threads. Pick the gauge scale you need (MPa, psi or bar); this unit is fitted with a round gauge scaled in MPa. Thread is a decode choice: PT is the standard, while G (BSPP) and NPT are catalogue options to order - this one is NPT. You can also specify the low-pressure type (up to 0.4 MPa), a reverse/check valve, or a bracket. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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.
Flow for the GR400 is published as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the figures from the AirTAC datasheet on request.
Yes - the gauge scale is a decode choice: MPa, psi or bar. This unit is fitted with a round gauge scaled in MPa; psi and bar scales are catalogue options you can order.
