The AirTAC GR60025JF2K AirTAC Air Pressure Regulator 1 in PT 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" 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 GR60025JF2K is an AirTAC GR-series air pressure regulator for compressed air, built for line size 600 with a 1 in PT threaded port. It is a regulation-only unit: it holds a stable downstream pressure set anywhere in its 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum working (inlet) pressure of 1.0 MPa (145 psi). This configuration carries an embedded square pressure gauge scaled in psi, a built-in reverse (check) valve that lets downstream air escape back through the unit when the upstream supply is lost, and no mounting bracket - the GR600 can also be panel-mounted.
This is a genuine AirTAC part. The GR family spans sizes 200 to 600, with PT as the standard thread and G (BSPP) or NPT available as order options, gauge choices including MPa, psi or bar scales, and a low-pressure type variant. Published flow data for this series is given as curves rather than a single rated figure, so ask us to 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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

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.

Installed at the take-off from a factory compressed-air ring main, the GR600 with its 1 in PT port holds a steady header pressure for downstream drop lines, with the psi gauge giving operators a direct local reading.
Feeding quarter-turn or gate valve actuators on a process line, the regulator keeps the actuator supply pressure fixed within its 0.05-0.9 MPa range, and the fitted check valve vents the actuator line safely if the plant air supply fails.
Mounted in the air preparation section of a press or material-handling machine panel, the GR600 regulates the supply to clamping and cylinder circuits, with panel mounting and no bracket suiting an enclosed cabinet installation.
Start with the port and size step: the GR600 with its 1 in PT connection is the largest step in the GR range (sizes 200 through 600), so match it to your main line size and the flow your circuit needs. Set the working pressure inside the 0.05-0.9 MPa (7-130 psi) adjustment range; if your circuit never exceeds 0.4 MPa, the GR low-pressure type is an alternative worth asking about. Choose the gauge scale you want to read - this unit ships with the embedded square gauge in psi, with MPa and bar scales and an external round gauge available. The fitted reverse (check) valve is a deliberate choice: keep it if you want downstream pressure vented back through the regulator on air failure, or order the version without it. Thread is PT as standard; G (BSPP) and NPT are catalogue options to specify when ordering. Flow for this series 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 GR-series flow only as characteristic curves, not as a single rated figure, so we do not quote a number here. Tell us your line size, inlet pressure and required downstream flow, and we will confirm the sizing against the datasheet curves on request before you order.
The trailing K in the code means a reverse (check) valve is fitted: when upstream air is lost, downstream pressure can escape back through the regulator instead of being trapped in the circuit. The F2 means the embedded square gauge is fitted and scaled in psi; MPa or bar scales and an external round gauge are available as order options.
