The AirTAC GR30010JF2TK AirTAC Air Pressure Regulator 3/8in NPT 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 GR30010JF2TK is an AirTAC GR-series air pressure regulator for compressed air, and regulation is the only function it performs: there is no filter element, no bowl and no drain in this unit. This configuration is the size 300 body with a 3/8 in NPT port, a standard regulation range of 0.05-0.9 MPa (7-130 psi) and a maximum inlet pressure of 1.0 MPa (145 psi). It ships as coded with an embedded square gauge reading in psi, a reverse/check valve fitted to hold the downstream setting, and no mounting bracket - the GR300 can also be panel-mounted where the application calls for it. Its operating temperature window is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line is available in sizes 200, 300, 400 and 600 with matching port steps, and can be ordered with G (BSPP) or NPT threads in place of the PT standard, with or without a gauge, with MPa, psi or bar gauge scales, as a low-pressure type (L) limited to 0.4 MPa, and with or without the reverse/check valve. 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.
| GR300 | G-series pressure regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 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). |
| F | Gauge shape: Square. 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. |
| 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 air cylinders on a clamping or press fixture, with the fitted check valve holding the setting if the main supply dips mid-cycle.
Regulate the feed to sealing jaws and wrapper actuators on a packaging line, with the psi square gauge giving operators a direct local reading at the machine.
Supply sortation gates and diverters on a conveyor line at a fixed, repeatable pressure so indexing and reject strokes stay consistent shift after shift.
Start with the port step: this unit is the size 300 at 3/8 in, one of four GR sizes (200/300/400/600), and the right size is the one whose flow curve covers your machine's air demand at working pressure - we can check that against the datasheet before you order. Then set the options that matter: gauge scale (this unit reads psi; MPa and bar scales are also available), the reverse/check valve, which this code includes to hold downstream pressure if the upstream supply dips, and the thread - PT is the catalogue standard, with G (BSPP) and NPT as orderable options, as on this unit. A low-pressure (L) version limited to 0.4 MPa exists if your line runs below the standard range. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
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 GR regulator flow as curves, not as a single rated number, so there is no one l/min or SCFM figure we can quote honestly. Send us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet on request.
K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply drops. F2 decodes as the embedded square gauge with a psi scale - MPa and bar scales are available on other codes - and T sets the 3/8 in port thread to NPT instead of the PT standard.
