The AirTAC GR60025F2GK AirTAC Air Pressure Regulator G1 1 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 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 GR60025F2GK is an AirTAC GR-series air pressure regulator for compressed air, built in the largest 600 size with a G1 (1 in) G-thread port. It reduces and holds a stable downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration carries the embedded square gauge with a psi scale for direct reading, a built-in reverse/check valve (code K) that holds downstream pressure when the upstream supply is removed, and a mounting bracket is included; the GR series is also panel-mountable. Operating temperature is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, offered in standard and low-pressure (L) types, with or without gauge, with MPa, psi or bar gauge scales, with an optional reverse/check valve, and in PT (standard), G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

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.

Dropping a 1 in compressed-air main down to a stable working pressure for a production hall, with the psi gauge giving operators a direct local reading at the header.
Feeding cylinders and actuators on a packaging or palletising line at a held pressure, with the check valve keeping the circuit pressurised if the upstream supply drops.
Setting and holding the clamping pressure on pneumatic press, clamp or workholding fixtures, where a steady regulated supply protects the tooling and the part.
Start with size and port: the 600 body with its 1 in G1 port is the correct step when your line runs at the top of the G-series port range; smaller 200/300/400 bodies with 1/8 to 3/4 in ports suit lighter duties, and the published flow curves - not a single rating - are what size the body, so confirm them against your demand. Choose the gauge scale to match your plant convention: this unit reads psi on the embedded square gauge, and MPa or bar scales plus an external round gauge are available. Decide whether a reverse/check valve (fitted here, code K) is needed to hold downstream pressure on supply loss. Pick the thread for your piping: PT is the standard, with G and NPT as orderable options. A mounting bracket is included, and GR can also be panel-mounted. If your setpoint never exceeds 0.4 MPa, the low-pressure (L) type is the alternative. Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 rather than a single rated figure, so no single flow number, Cv or SCFM value can be quoted here. Tell us your inlet pressure, set pressure and air demand, and we will confirm the flow figures from the datasheet for this exact 600-size, 1 in unit before you order.
The K means a reverse/check valve is fitted: if the upstream supply is lost, the valve holds the downstream pressure instead of venting it. It is a real orderable choice on GR regulators - the same unit without the valve simply omits the K from the code - so select it based on whether your circuit needs pressure retained on supply loss.
