The AirTAC GR60025C2GK AirTAC Air Regulator G1 (1 in) with Check Valve 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 GR60025C2GK is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose, anywhere between 0.05 and 0.9 MPa (7-130 psi). This is the size 600 unit with a 1 in port in G (BSPP) thread, fitted with an external round gauge reading in psi and a reverse (check) valve, so downstream pressure is held if the upstream supply is interrupted. Mounting bracket is included, and the body is also panel-mountable.
This is a genuine AirTAC part. The GR line runs from size 200 to 600 with ports from 1/8 in to 1 in, in PT (standard), G or NPT thread, with embedded square or external round gauges in MPa, psi or bar scales, and an optional low-pressure type. Medium is compressed air only; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G family. We confirm flow and full datasheet figures 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.

| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

| 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, repeatable working pressure for a 1 in air line feeding a pneumatic press or clamp cylinder, so forming and clamping force stays consistent shift after shift. The check valve holds the setting if supply pressure dips.
Drop down from a main header at the entry to a packaging or case-erector cell and regulate the actuator supply to the machine's specified pressure, with the round psi gauge giving operators a local, readable setpoint.
Regulate the air feeding large-diameter actuators on gate, diverter and slide valves in a bulk handling line, where the 1 in port and wide -20 to 70 C temperature range suit demanding plant environments.
Start with the port: this unit is 1 in G thread, so match it to your line size or step up a size if your flow demand is near the top of the range - the GR series steps through 200/300/400/600 with ports from 1/8 in to 1 in. Choose the gauge scale you want (this one reads psi; MPa and bar are available), and decide whether you need the reverse/check valve, which this configuration includes. Thread is G here; PT is the standard and NPT is an orderable option. A mounting bracket is included and the unit can also be panel-mounted.
One honest note on sizing: AirTAC publishes regulator flow as curves, not as a single rated figure, so we do not quote a flow number. Tell us your application and we will confirm the right size against the datasheet before you order.
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 characteristic curves rather than a single rated figure, so we do not quote a flow number for this unit. Send us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet before you order.
K means a reverse (check) valve is fitted. If upstream supply is lost or deliberately shut off, the valve holds the regulated downstream pressure instead of venting it back through the regulator - useful on circuits where a load must stay clamped or positioned. This configuration also includes the external round gauge reading in psi; square embedded gauges and MPa or bar scales are available as options.
