The AirTAC GR60025C3TK AirTAC Air Pressure Regulator NPT1 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 GR60025C3TK is an AirTAC GR600 air pressure regulator for compressed air, built around regulation only: it sets and holds downstream pressure, with no filter element and no bowl. This 600-size unit carries a 1 in NPT port and a standard-type regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi). The C3 suffix means an external round gauge scaled in bar is fitted, and the K suffix adds a reverse/check valve so downstream pressure is held if the supply drops. It operates from -20 to 70 C, a wider temperature window than the rest of the G family, and a mounting bracket is included; the GR series is also panel-mountable.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with optional low-pressure type (up to 0.4 MPa), gauge scale choices and a reverse/check valve. Flow for this series 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.

| 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. |
| 3 | Gauge scale: bar. 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 feeding spray guns and air-assist atomisers on a paint booth line, with the bar-scaled round gauge giving operators a clear setpoint readout at the wall drop.
Regulate the supply to pneumatic cylinders that press and eject cartons on a packaging conveyor, holding the set pressure through supply dips thanks to the fitted reverse/check valve.
Drop the header pressure to a safe working level at each CNC machining centre's air inlet, with the 1 in NPT port matching large machine-shop drop piping and the bracket easing wall mounting.
Start with the port step: the 600 size is the largest in the GR range and takes a 1 in port, so size up from 200/300/400 when the line's flow demand points to larger piping - and confirm that against the published flow curves with us before ordering, since the catalogue gives curves rather than one rated number. Next, pick the gauge: this code carries a round external gauge scaled in bar, while psi (scale 2) and MPa (scale 1) versions exist to match your reading convention. Choose the thread to suit the install - PT is the standard, with G (BSPP) and NPT as orderable options, and this unit is specified in NPT. Add the K reverse/check valve where a drop in supply must not dump downstream pressure, and note the standard type covers the full 0.05-0.9 MPa range; a low-pressure L variant (up to 0.4 MPa) is available if your setpoint sits low. A bracket is included and panel mounting is possible.
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 as curves rather than a single rated figure, so we do not quote one number. Tell us your inlet pressure, set pressure and expected demand, and we will confirm the sizing against the datasheet curves on request before you order.
Yes. The C3 code on this model fits an external round gauge scaled in bar; the same gauge is available with scale 2 (psi) or scale 1 (MPa), and an embedded square gauge is the alternative. Pick the scale that matches the instruments your technicians already read, and specify it in the model code when ordering.
