The AirTAC GR30015JF1T 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 GR30015JF1T is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from your compressed-air supply. This 300-size unit has NPT1/2 ports, a standard regulation range of 0.05-0.9 MPa (7-130 psi) and a maximum inlet pressure of 1.0 MPa (145 psi). An embedded square gauge scaled in MPa is fitted, and the unit is rated for -20 to 70 C. No mounting bracket is included; the GR family is also panel-mountable.
This is a genuine AirTAC part. The GR family spans 200/300/400/600 sizes with ports from 1/8 in. to 1 in., a low-pressure type option, gauge scale choices (MPa, psi or bar) and thread options: PT is the standard thread, with G and NPT available as catalogue options to order. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 a stable atomizing pressure for spray guns in a finishing booth, downstream of filtration, so coating quality does not drift as supply pressure moves.
Regulate the air feeding a small press or clamping fixture so the operator sets one repeatable working pressure for the cycle.
Drop the header pressure to the level a packaging machine's cylinders and actuators were designed for, holding it steady through the shift.
Step up through the GR sizes (200/300/400/600) as your port size and required flow grow; this 300-size unit gives you NPT1/2 ports. The standard type covers a 0.05-0.9 MPa (7-130 psi) adjustment range; a low-pressure type (up to 0.4 MPa) exists if your setpoint sits low. Gauge scale is your choice of MPa, psi or bar, and the gauge can be the embedded square type shown here or an optional external round type. Thread is PT as standard, with G and NPT as orderable options - this code carries NPT. Brackets are optional on GR, which can also be panel-mounted. One honest note on sizing: flow is published as curves, not a single rated figure, so ask us to confirm the sizing against your application before ordering.
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 regulator flow as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Send us your application details and we will confirm the sizing from the datasheet on request.
The trailing T in the code specifies NPT threads. PT is the standard thread for the GR family, with G (BSPP) and NPT available as catalogue options to order - this is a specification choice on the order, not a delivery matter.
