The AirTAC GR30015F2TK AirTAC Air Pressure Regulator NPT1/2 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 PT1/2" 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 GR30015F2TK is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream line pressure steady at the setting you dial in. This is the 300 size with 1/2 in NPT ports, the standard regulation range of 0.05-0.9 MPa (7-130 psi), a square pressure gauge fitted and reading in psi, and a built-in reverse (check) valve so downstream pressure cannot back-feed through the unit. The bracket is included, and because it is a GR it can also be panel-mounted. It is a regulator only - there is no filter, no bowl and no drain, so pair it with a filter if your air needs cleaning upstream.
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, thread options PT (standard), G (BSPP) and NPT, gauge scales in MPa, psi or bar, a low-pressure type and a reverse-valve option, so there is a configuration for most regulation tasks. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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.

| (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.

Set and hold a stable, reduced pressure feeding a pneumatic press or clamping cylinder, so the tooling sees consistent force stroke after stroke regardless of header-pressure swings.
Regulate the supply to packaging machinery actuators and grippers on a 1/2 in NPT drop, keeping seal bars and pick-and-place motions running at the pressure the machine was set up for.
Dial in a fixed, repeatable supply pressure to spray equipment or booth air tools, with the psi-scale gauge giving operators a clear readout at the point of use.
Start with the port: this unit is 1/2 in NPT, so match it to your line size or step up a size if your flow demand is high - the GR range runs 200/300/400/600 from 1/8 in to 1 in. Set the working range: the standard GR covers 0.05-0.9 MPa (7-130 psi); if your setpoint sits below that band, ask about the low-pressure (L) type rated up to 0.4 MPa. Choose your gauge scale (MPa, psi or bar) and whether you want the embedded square gauge or the optional external round gauge. Pick the thread: PT is the standard, with G (BSPP) and NPT as orderable options - this unit is already NPT. Decide on the reverse/check valve (fitted here as K) if back-flow protection matters, and on the bracket, which is included with this code and suits panel mounting too. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
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 regulator flow as performance curves, not as a single rated number, so we do not quote a figure here. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet curves for this exact model before you order.
T means 1/2 in NPT threads (PT is the standard option, G/BSPP is also orderable), F2 means the square gauge is fitted and reads in psi, and K means a reverse/check valve is built in. A GR is a regulator only - it has no filter or bowl - so if your compressed air needs water and particle removal, add a GF filter or a combined GFR unit upstream.
