The AirTAC GR60025F1T AirTAC Air Pressure Regulator NPT1 (1 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 GR60025F1T is an AirTAC GR-series air pressure regulator in the largest 600 size, supplied with a 1 in NPT thread. It does one job only: reducing and holding downstream air pressure, adjustable across 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration carries the embedded square pressure gauge reading in MPa, and because it is a regulator it has no filter bowl, no drain and no lubricator - pair it with a filter if the line needs one. It operates in ambient temperatures from -20 to 70 C, the widest range in the G family.
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, and options include G or NPT thread in place of the PT standard, psi or bar gauge scales, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and panel mounting as well as the included bracket. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |

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.

Dropping a 1 in plant air main down to a controlled working pressure feeding clamp and counterbalance cylinders on a mechanical press line, with the square gauge giving the setter a direct MPa readout at the header.
Holding a steady downstream pressure for the pneumatic actuators that drive filler valves, capping heads and reject gates on a bottling line, so machine timing does not drift as the compressor load changes through a shift.
Giving a maintenance technician a dedicated adjustment point for the tool-change and clamping circuit on a machining centre, where the regulator setting is tuned once and checked against the gauge during preventive service.
Start with the port step: the GR600 takes a 1 in connection, so match it to the main line size your actuators and cylinders actually need - stepping down to a smaller regulator body just throttles your own supply. Set the working pressure inside the 0.05-0.9 MPa (7-130 psi) adjustment range; if your process runs below that ceiling anyway, the low-pressure L type capped at 0.4 MPa is worth considering. Choose the gauge scale to suit your team - this unit ships with the square gauge in MPa, and psi or bar scales are orderable - and specify PT (standard), G or NPT thread when ordering. The bracket is included and the GR600 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 here. Send us your application details and we will confirm the right size against the datasheet before you order.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. 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 figure, so we do not quote a flow number, Cv or SCFM value. Send us your line size and application and we will confirm the relevant datasheet figures on request before you order.
Yes. The GR60025F1T as coded carries the embedded square gauge with an MPa scale, and the same square gauge is available in psi (scale 2) or bar (scale 3) as an order option. An external round gauge is also available if you prefer that style.
