The AirTAC GR40015JF2K AirTAC Air Pressure Regulator PT1/2 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 AirTAC GR40015JF2K is a pure air pressure regulator from the GR400 series: it reduces and holds a stable downstream pressure from a compressed-air supply, with no filtration or lubrication function. This configuration carries a PT1/2 (1/2 in) PT-threaded port, the standard regulation range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and an embedded square pressure gauge scaled in psi (external round gauges with MPa/psi/bar scales are optional). The K code means a reverse/check valve is fitted, and the J code means no mounting bracket is included - the GR body is also panel-mountable. As a GR unit it has no drain bowl, and it operates in ambient temperatures from -20 to 70 C, a wider window than the rest of the G family.
This is a genuine AirTAC part. The GR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with optional low-pressure type (up to 0.4 MPa), gauge scale choices, reverse/check valve and bracket options. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures 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.

| (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. |
| 2 | Gauge scale: psi. 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.

On a machining cell where hydraulic-free pneumatic clamps grip workpieces, the GR40015JF2K holds a steady 1/2-in-line pressure to the clamp cylinders so grip force stays repeatable across the shift, while the fitted check valve holds the clamp setting if shop air dips.
In a spray-booth air make-up drop, this regulator sets and keeps the atomizing pressure to the spray guns independent of header fluctuations, with the psi-scaled square gauge giving operators a direct local reading at the point of use.
Feeding stoppers, pushers and diverter cylinders on a packaging conveyor, the GR40015JF2K regulates the 1/2-in branch supply so actuator speed and impact stay consistent, and the check valve keeps the branch pressurized during upstream blow-down.
Start with the port step: GR400 with a PT1/2 (1/2 in) PT port sits in the middle of the 200/300/400/600 size ladder, so step up or down according to the air demand of the line it feeds - we will check the published flow curves against your requirement before you order. Then fix the options this code carries: the embedded square gauge is scaled in psi here (MPa and bar scales are available), the K code adds a reverse/check valve so downstream pressure is held if the upstream supply drops, and the J code omits the mounting bracket - choose a bracket code if you want panel or surface fixing hardware included. Thread is PT as standard; G (BSPP) and NPT are orderable options if your pipework needs them. If your circuit never exceeds 0.4 MPa, ask about the GR low-pressure (L) type. Flow is published as curves, not a single rating, so ask us to confirm sizing against the application before ordering.
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, not as a single rated number, so there is no one l/min or SCFM figure we can honestly quote. Send us your line pressure, set pressure and expected air consumption, and we will confirm the flow curves and sizing from the datasheet on request before you order.
The F2 code means an embedded square pressure gauge scaled in psi is included; MPa and bar scales are available as alternatives. The K code means a reverse/check valve is fitted, which holds the downstream pressure if the upstream supply is lost. This unit is also the standard (not low-pressure) type, with a 0.05-0.9 MPa (7-130 psi) adjustment range, PT1/2 PT-threaded port, no mounting bracket, and a -20 to 70 C operating range.
