The AirTAC GR40010JC2T AirTAC Air Pressure Regulator, NPT 3/8 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 PT3/8" 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 GR40010JC2T is an AirTAC GR400 series air pressure regulator for compressed air, built around pressure regulation only - no filtration and no lubrication. This 400-size unit is configured with a 3/8 in NPT port, the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a maximum working (inlet) pressure of 1.0 MPa (145 psi). It ships configured with an external round gauge on the psi scale, and the trailing T sets the thread to NPT. No mounting bracket is included with this code, and no reverse/check valve is fitted; the GR body is also panel-mountable. Operating temperature is -20 to 70 C, wider than the rest of the G-series families.
This is a genuine AirTAC part. The GR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, in PT (standard), G and NPT threads, with optional round or square gauges on MPa, psi or bar scales, a low-pressure type, an optional reverse/check valve, and bracket or no-bracket variants. Flow figures for the GR400 are published as curves rather than a single rating, 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.

| 10 | Port size PT3/8". 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

On a workshop pneumatic press, this regulator sits in the 3/8 in supply line ahead of the cylinder valve, letting the operator set and hold a stable working pressure for consistent forming and staking jobs.
On a carton-sealing or case-packing conveyor, the unit regulates the air feeding grippers and pusher cylinders, keeping actuator pressure steady as multiple stations cycle on the same main line.
At a machine drop from a factory ring main, this 400-size regulator steps the header pressure down to the level the machine's valves and cylinders were designed for, with a psi gauge for local setting.
Start with size and port: the 200/300/400/600 step sets the port size and the flow path, so match the 3/8 in NPT port on this unit to your supply line and the air demand of the downstream cylinders or valves. Then fix the options that this code settles: the psi round gauge (square embedded gauges and MPa or bar scales are available on other codes), the NPT thread where PT is the standard and G is the alternative, the no-bracket configuration, and the standard regulator type - a low-pressure type capped at 0.4 MPa exists if your setpoint sits low. If you want a reverse/check valve to hold downstream pressure on supply loss, that is a separate code with K.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the datasheet curve and sizing against your required flow 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-series flow as performance curves rather than a single rated figure, so we do not quote a flow number for this regulator. Tell us your line size and the air demand of your downstream equipment, and we will confirm the datasheet curve and check the sizing for your application on request.
In the GR code structure, C selects the external round gauge, the scale digit 2 selects psi, and J specifies no mounting bracket. Other codes in the same series give you the embedded square gauge, MPa or bar scales, or a bracket included - and the GR body is panel-mountable regardless. Pick the code that matches how you want to read and mount the regulator.
