The AirTAC GR30010JF1TK AirTAC Air Pressure Regulator 3/8 in 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 AirTAC GR30010JF1TK is a size 300 air pressure regulator for compressed air, fitted with a 3/8 in NPT port. It regulates downstream pressure across a 0.05-0.9 MPa (7-130 psi) adjustment range and handles a maximum inlet pressure of 1.0 MPa (145 psi). This configuration carries an embedded square gauge scaled in MPa, a built-in reverse (check) valve that lets downstream pressure hold when the upstream supply is removed, and no mounting bracket; the GR series 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 sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, gauge scales in MPa, psi or bar, a low-pressure type limited to 0.4 MPa, and optional brackets. Because flow is published as curves rather than a single rating, we confirm the datasheet and sizing 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. |
| 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, reduced pressure to the press cylinder so clamping and forming stations run at the force the fixture was designed for, with the check valve holding the set pressure if the main supply drops.
Feed a dedicated reduced-pressure branch to sealers, vacuum generators and small actuator banks on a cartoning or wrapping line, reading the setpoint at a glance on the square MPa gauge.
Regulate the air to sorting gates, stoppers and pusher cylinders on a material-handling conveyor so product is diverted gently and consistently, with the reverse valve protecting the circuit during supply shutdowns.
Start with the port size: step up from 200 to 600 as your air demand grows, matching the 3/8 in thread here to your supply line. Set the working pressure inside the 0.05-0.9 MPa (7-130 psi) range; if your circuit runs below that, ask about the GR low-pressure type (up to 0.4 MPa). Choose the gauge scale you want to read - MPa, psi or bar - and decide whether the built-in reverse (check) valve suits your circuit or whether you prefer the version without it. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order, as is the mounting bracket. Flow is published as curves, not a single rating, so 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 regulator flow as curves rather than a single rated figure, so no single l/min or SCFM number is quoted here. Tell us your line pressure, set pressure and the actuators you are feeding, and we will confirm the datasheet flow curve and correct size for your application on request.
The K in the code means a reverse (check) valve is fitted, so downstream pressure is retained when the upstream supply is removed - useful for circuits that must hold position or pressure during a shutdown. The J in the code means no mounting bracket is included; the GR series is also panel-mountable, and bracketed versions are available in the range if you prefer.
