The AirTAC GR30010C3T AirTAC Air Pressure Regulator, NPT3/8 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 AirTAC GR30010C3T is a compressed-air pressure regulator in the GR300 series, fitted with a 3/8 in NPT port. It does one job only: it holds a stable downstream pressure from the full 1.0 MPa (145 psi) maximum inlet, adjustable across 0.05-0.9 MPa (7-130 psi). This configuration is the standard regulator type with an external round gauge on a bar scale, a mounting bracket included, and it is also panel-mountable. As a regulator it has no filter, no bowl and no drain, so it is used where the air is already filtered and only pressure control is needed.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include G (BSPP) or NPT thread in place of the PT standard, MPa, psi or bar gauge scales, a low-pressure type (L) limited to 0.4 MPa, a reverse/check valve (K), and a no-bracket (J) variant. Flow is published as curves rather than a single rated figure, so we 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.

| (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. |
| 3 | Gauge scale: bar. 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 a repeatable working pressure on the air line feeding a bench or C-frame pneumatic press, so forming and staking strokes stay consistent shift after shift.
Regulate the pressure branch feeding sealing jaws and carton-closing actuators on a packaging line, downstream of the existing filter, where only pressure control is required.
Supply pick-and-place grippers and small clamps on a robotic assembly cell from a dedicated regulated branch, keeping actuation pressure independent of shop-air swings.
Start with the port step: this unit is size 300 with a 3/8 in NPT port, and the GR family steps through 200, 300, 400 and 600, where the larger sizes carry larger ports and more flow. Match the size to your line's flow demand rather than the pipe alone. Choose the gauge scale you want to read at a glance: MPa, psi or bar; this unit carries the round gauge on bar, and the embedded square gauge is the standard alternative. Thread is the other decodable choice: PT is the standard, with G (BSPP) and NPT available as order options - this unit is the NPT version. If your working pressure never exceeds 0.4 MPa, the low-pressure L type is the matched choice; if the line must keep flowing on supply failure, specify the K reverse/check valve option. A bracket is included, and GR also panels mounts.
One honest note before you order: AirTAC publishes regulator flow as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm sizing against the datasheet curves before you commit.
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 characteristic curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet curves on request before you order.
This model is the NPT 3/8 in version with an external round gauge reading in bar. If your team reads psi or MPa, the same regulator is available with those gauge scales, and the embedded square gauge is the standard alternative. On thread: PT is the catalogue standard, while G (BSPP) and NPT are order options - choose the one that matches your pipework, as this unit is supplied with NPT.
