The AirTAC GR60025F3TK AirTAC Air Pressure Regulator NPT1 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 GR60025F3TK is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream working pressure steady as upstream supply and demand fluctuate. This 600-size unit is the largest in the GR line and is decoded with a 1 in NPT port, a standard regulation range of 0.05-0.9 MPa (7-130 psi), and an embedded square pressure gauge scaled in bar (an external round gauge in MPa, psi or bar is a catalogue option). The K in the code means a reverse (check) valve is fitted, and the mounting bracket is included; GR bodies are also panel-mountable.
This is a genuine AirTAC part. The GR family 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 a low-pressure type (L) available up to 0.4 MPa. GR units handle a maximum inlet pressure of 1.0 MPa (145 psi) and operate from -20 to 70 C, a wider temperature window than the rest of the G series. Flow 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. |

| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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 and hold the working pressure feeding a pneumatic press or clamping fixture, with the 1 in NPT port carrying the full branch supply and the check valve holding the setting if upstream pressure dips.
Regulate the supply to a packaging or case-sealing machine's actuator circuit, using the bar-scaled square gauge for a clear local setpoint readout at the machine.
Trim pressure on individual branch take-offs from a factory air distribution header, keeping each downstream zone at its own setpoint independent of the main line.
Size the GR by port step against your air demand: 200 through 600 cover 1/8 in to 1 in, and the 600 size with its 1 in port suits the highest-flow branch of the range. Because flow is published as curves rather than a single rating, tell us your line pressure and consumption and we will confirm sizing against the datasheet before you order. Then settle the decodable options: gauge scale (1 = MPa, 2 = psi, 3 = bar, or no gauge with N), thread (PT is the standard, G and NPT are order options), the L low-pressure type if your setpoint stays at or below 0.4 MPa, the K reverse/check valve, and bracket or panel mounting. Note the GR is regulation only: it has no filter, no bowl and no drain, so pair it with a GF or GFR upstream if you need water and particulate removal.
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 flow as curves rather than a single rated figure, so there is no one rated flow number we can honestly quote. Send us your inlet pressure, setpoint and expected air consumption, and we will confirm the sizing against the datasheet on request before you order.
K means a reverse (check) valve is fitted in this unit, and F3 specifies the embedded square gauge with a bar scale. If you would rather read MPa or psi, the equivalent codes use scale 1 or 2, and an external round gauge is available as a catalogue option.
