The AirTAC GR60025JF3TK AirTAC Air 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 GR60025JF3TK is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady at the value you set, and it carries no filter, no bowl and no lubricator. This is the largest GR frame, the 600 size, with a 1 in NPT inlet and outlet port, so it is intended as the pressure-control point on a main air line or a high-consumption drop. The standard adjustment range is 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit is rated for -20 to 70 C, a wider temperature window than the rest of the G-series. The code's F3 specifies the embedded square gauge scaled in bar, and the K specifies a built-in reverse (check) valve that holds the downstream setting if upstream supply is lost. No mounting bracket is included with this configuration; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with gauge, bracket, low-pressure and check-valve options to suit the line. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for this exact model before you order.

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. |
| J | Supplied without bracket. |

| 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.

Dropping a plant's 1 in distribution header to the working pressure for a production hall, with the square bar gauge giving operators a local reading of the regulated line pressure.
Setting and holding the clamping or pressing force on a large air-powered press or forming machine, where the reverse valve keeps the set pressure stable if the upstream supply dips.
Regulating supply to air-operated equipment on loading docks and vehicle-servicing rigs, where the GR's -20 to 70 C range covers unheated yard and winter conditions.
Sizing a GR starts with the port step: the 600 size carries the 3/4 in and 1 in ports, so choose it when the line itself is 3/4 in or 1 in and let the published flow curves, not a single number, settle the final choice - we will check them against your application on request. Set the downstream pressure you need within the 0.05-0.9 MPa (7-130 psi) range; if your process runs below that, the GR low-pressure type (code L) is the variant to discuss. The gauge on this unit is the embedded square type scaled in bar; psi and MPa scales and an external round gauge are the other catalogue choices. Thread is NPT here, ordered as an option - PT is the standard thread, and G is the third choice. The K code's reverse valve suits circuits where the set pressure must be held against supply loss, and the J code means no bracket is fitted, so plan for panel mounting or order a bracket 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 GR flow as curves rather than a single rated figure, so we do not state a number here. Tell us your line pressure and the flow your application needs and we will confirm the datasheet curve for this exact model before you order.
Both are read from the code. The K gives a built-in reverse (check) valve that holds the downstream setting if upstream supply is lost, and F3 specifies the embedded square gauge scaled in bar - psi and MPa scales, an external round gauge, and a no-gauge build are the other catalogue options.
