The AirTAC GR30015JF2G AirTAC Air Pressure Regulator G1/2 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 GR30015JF2G is an AirTAC GR300 series air pressure regulator for compressed air, dedicated purely to downstream pressure regulation - it contains no filter and no bowl, so it is fitted where the air is already filtered and only a stable, adjustable pressure is needed. This configuration is the size 300 body with a G1/2 (BSPP) female port, the standard regulation range of 0.05-0.9 MPa (7-130 psi), a fitted embedded square gauge with psi scale, and no mounting bracket (J code); the GR300 is also panel-mountable. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -20 to 70 C, which is wider than the rest of the G-series because the GR has no polycarbonate bowl.
This is a genuine AirTAC part. The GR family is available in sizes 200, 300, 400 and 600 with matching port sizes, and can be ordered with G (BSPP) or NPT threads as well as the PT standard, with or without a bracket, with a round external gauge as an alternative to the embedded square gauge, with MPa, psi or bar gauge scales, and as a low-pressure type. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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 workshop pneumatic press or clamping fixture, this regulator holds the cylinder supply at the pressure the tooling was set up for, with the psi gauge giving the operator a direct readout at the setpoint.
Downstream of a filter on a packaging or cartoning line, the GR30015JF2G regulates the supply to actuators and vacuum generators, keeping machine pressure stable as stations cycle.
On a robotic pick-and-place cell, the regulator trims the supply pressure to the gripper and end-of-arm tooling so part handling force stays consistent across the shift.
Start with the port and size step: the GR300 with its 1/2" class port sits in the middle of the GR range (200/300/400/600), and the right step depends on the air demand of the circuit downstream - since flow is published only as curves, not a single rating, ask us to confirm sizing against your application before ordering. This unit carries the standard regulation range of 0.05-0.9 MPa (7-130 psi); a low-pressure type (L) limited to 0.4 MPa exists if your setpoint is lower. The fitted square gauge here reads in psi; MPa and bar scales are also available, and a round external gauge can be specified instead. Thread choice matters at ordering time: PT is the standard, while G (BSPP) - as coded on this unit - and NPT are catalogue options. Brackets are optional (this unit is ordered without one) and the GR300 is also panel-mountable.
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 GR-series flow as characteristic curves rather than a single rated figure, so we do not quote one number. Tell us your inlet pressure, setpoint and downstream air demand, and we will confirm the flow from the datasheet curves on request before you order.
F is the square (embedded) gauge and 2 is the psi scale, so this unit ships with a psi-reading square gauge; MPa and bar scales, and a round external gauge, are order options. The trailing G is the G (BSPP) thread - PT is the standard thread and NPT is also available as a catalogue option, so order the suffix that matches your piping.
