The AirTAC GR60025C1TK 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 GR60025C1TK is a genuine AirTAC GR-series air pressure regulator in the largest 600 size, with 1 in NPT ports. It does one job only: reducing and holding a stable downstream pressure from a compressed-air supply, adjustable across 0.05-0.9 MPa (7-130 psi). This configuration is fitted with an external round pressure gauge reading in MPa, and the K option adds a reverse (check) valve so downstream air does not back-feed through the unit when upstream pressure is lost. Maximum inlet pressure is 1.0 MPa (145 psi), and the GR series carries the widest temperature window in the G family at -20 to 70 C.
As a genuine AirTAC part, the GR600 is the top of a range spanning sizes 200, 300, 400 and 600, with port options from 1/8 in up to 1 in, G (BSPP) and NPT thread variants alongside the standard PT, gauge scale choices, a low-pressure type, and bracket or panel mounting. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. |
| 1 | Gauge scale: MPa. 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.

Drops the compressor receiver line down to a controlled working pressure at a 1 in distribution header feeding a production hall, holding the setpoint steady as downstream draw rises and falls between shifts.
Sits in the supply line to a big air-operated press or clamp fixture, setting the working pressure the cylinders see and the check valve holding that setting in the circuit if the upstream supply drops.
Regulates the air feeding quarter-turn pneumatic actuators on a process line, so every valve in the branch strokes at the same set pressure, with the round MPa gauge giving operators a local reading.
Start with the port step: the 600 size is the largest in the GR range and carries the 1 in connection here, so size up from the 200/300/400 steps when the main line and expected demand call for it - flow is published as curves, not a single rating, so send us your demand figures and we will confirm sizing against the datasheet before you order. Then settle the decode choices that this code already locks in: NPT thread (PT is the standard, G and NPT are the order options), a round external gauge on the MPa scale (psi and bar scales are the alternatives), and the K reverse/check valve. A mounting bracket is included, and GR is also panel-mountable.
If your supply pressure never needs to go above 0.4 MPa, the GR low-pressure (L) type exists as an alternative; otherwise this standard type with its 0.05-0.9 MPa adjustment covers the usual working band. If you would rather read gauge in psi or bar, or prefer no gauge at all (N), those are catalogue options on the same body.
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, not as a single rated number, so we do not quote a l/min, m3/h, SCFM or Cv figure here. Send us your line size and demand and we will confirm the flow from the datasheet on request before you order.
K means a reverse (check) valve is fitted, so downstream air cannot back-feed through the regulator when upstream pressure is lost. C1 means this unit carries the optional external round gauge on the MPa scale; the embedded square gauge is the standard fitting, and psi or bar scales are the other catalogue choices.
