The AirTAC GR60025C2K 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 GR60025C2K is an AirTAC GR-series air pressure regulator in the largest 600 size, with a PT1 (1 in) port and PT (JIS) thread as standard. It is a regulation-only device: it reduces and holds a stable downstream pressure from your compressed-air supply, and it carries no filter, no bowl and no lubricator. This configuration is fitted with an external round pressure gauge reading in psi and a reverse (check) valve, which lets downstream air flow back past the regulator when the upstream supply is vented or shut off. The standard adjustment range is 0.05-0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -20 to 70 C - the widest temperature window in the G family.
This is a genuine AirTAC part. The GR line spans the 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, optional G (BSPP) and NPT threads in place of the PT standard, an optional low-pressure type limited to 0.4 MPa, gauge or no-gauge builds, and panel-mount capability. Flow for the GR600 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.

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 header pressure for an entire production hall downstream of the compressor room, with the 1 in port matching the main distribution line and the psi gauge giving operators a direct local reading.
Feed a bank of air-powered fixtures, clamps or actuators on an automated line from one regulated drop, holding a consistent setpoint so downstream valves and cylinders behave predictably shift after shift.
Regulate supply pressure to an air-over-oil intensifier or pneumatic press circuit where the required working pressure sits well below line pressure, with the check valve letting the circuit vent back when the supply is isolated.
Start with the port and size step: this 600-size unit takes a 1 in PT connection, the largest in the range, so it belongs on main air lines and high-demand headers rather than point-of-use drops - and because flow is published as curves, not a single rating, ask us to confirm sizing against your actual air demand before ordering. Decide the gauge: this code specifies the external round gauge with a psi scale (scales 1 and 3 give MPa and bar instead; code N omits the gauge entirely). The K in the code means a reverse/check valve is fitted - choose this when venting or shutting off upstream should let downstream air escape back through the regulator. The thread here is PT as standard; G (BSPP) and NPT are catalogue options you can order instead. A mounting bracket is included, and the GR is also panel-mountable. If your working pressure never exceeds 0.4 MPa, ask about the low-pressure (L) variant.
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 performance curves rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure for this unit. Tell us your line size, inlet pressure and required downstream flow, and we will confirm the datasheet curve figures for the GR600 on request before you order.
C2 specifies the external round pressure gauge with a psi scale (C1 is MPa, C3 is bar, and N in that position means no gauge), and K means a reverse (check) valve is fitted so downstream air can flow back when the upstream side is shut off or vented. Both are catalogue choices: you can order the same GR600 1 in regulator with a different gauge scale, no gauge, or without the check valve, and with G (BSPP) or NPT threads instead of the PT standard.
