The AirTAC GR60025F2TK AirTAC Air Pressure Regulator NPT 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 GR60025F2TK is an AirTAC GR-series air pressure regulator for compressed air only. It does one job: it holds a stable downstream pressure set anywhere in its 0.05-0.9 MPa (7-130 psi) adjustment range. This is the 600 size, the largest in the GR line, with 1 in NPT ports, and it is the standard (not low-pressure) type. The code confirms a square pressure gauge on the psi scale fitted as standard, a reverse/check valve (K) so downstream pressure is held if the upstream supply drops, and a mounting bracket included; the GR body is also panel-mountable. The medium is compressed air, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -20 to 70 C - wider than the rest of the G series, which makes GR the regulator to specify where colder plant air is a factor.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with ports from 1/8 in up to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, an optional low-pressure type limited to 0.4 MPa, gauge scales in MPa, psi or bar, and an optional reverse/check valve. AirTAC publishes flow for this series as curves rather than a single rated figure, so send us your application details and we will confirm the sizing and full datasheet figures on request 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. |

| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

| Line order | Filter first, then regulator, then lubricator |
Point-of-use regulation for the pneumatic clamps and swing cylinders on a machining centre, holding a steady clamp pressure on a 1 in main drop so part holding does not drift as the compressor cycles.
Regulating the supply to stopper cylinders, pushers and gate actuators on a bottling or canning conveyor, where a stable set pressure keeps indexing consistent across a full shift.
Trimming branch-line pressure on a weaving or spinning floor, with the check valve holding the set pressure at each drop when upstream demand elsewhere in the mill surges.
Pick the GR size by the air demand of the circuit, not just the pipe: 200, 300, 400 and 600 step up in both port size and flow capacity, and this GR600 sits at the top with 1 in ports. Because AirTAC publishes flow as curves rather than a single rated number, ask us to check the curve against your required flow at your set pressure before you commit. Then settle the decode choices: standard type (this unit) versus the L low-pressure type capped at 0.4 MPa; gauge scale psi (this unit), MPa or bar; and whether a reverse/check valve is wanted - the K in this code means one is fitted. On threads, PT is the catalogue standard and G (BSPP) and NPT are order options; this unit carries NPT. A mounting bracket is included and the GR body can also be panel-mounted. If your line needs filtration or lubrication as well, that is a different G-series family - GR regulates pressure only.
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 flow for the GR series as curves, not as a single rated number, so there is no honest one-line flow figure to quote. The GR600 is the largest size in the family with 1 in NPT ports, but the right check is against your actual demand: send us your required flow and set pressure and we will confirm the sizing from the datasheet curves on request before you order.
The code decodes as: GR regulator family, 600 size, 25 = 1 in ports, T = NPT thread, F2 = square gauge on the psi scale, K = reverse/check valve fitted. All of these are catalogue choices: thread is PT as standard with G (BSPP) and NPT as options, the gauge can be ordered on MPa, psi or bar scales, a round external gauge is available, and the K check-valve option can be included or left off. There is no bowl, filter or drain on any GR - if you need those, that is a GF, GFR, GFC or GC unit.
